-    liblzma: Fix compilation of fastpos_tablegen.c.
-    
-    The macro lzma_attr_visibility_hidden has to be defined to make
-    fastpos.h usable. The visibility attribute is irrelevant to
-    fastpos_tablegen.c so simply #define the macro to an empty value.
-    
-    fastpos_tablegen.c is never built by the included build systems
-    and so the problem wasn't noticed earlier. It's just a standalone
-    program for generating fastpos_table.c.
-    
-    Fixes: https://github.com/tukaani-project/xz/pull/69
-    Thanks to GitHub user Jamaika1.

-    liblzma: Use lzma_attr_visibility_hidden on private extern declarations.
+    Build: Update po/*.po files only when needed
     
-    These variables are internal to liblzma and not exposed in the API.
+    When po/xz.pot doesn't exist, running "make" or "make dist" will
+    create it. Then the .po files will be updated but only if they
+    actually would change more than the POT-Creation-Date line.
+    Then the .gmo files would be generated from the .po files.
+    This is the case before and after this commit.
+    
+    However, "make dist" and thus "make mydist" did a forced update
+    to the files, updating them even if the only change was the
+    POT-Creation-Date line. This had pros and cons: It made it clear
+    that the .po file really is in sync with the recent strings in
+    the package. On the other hand, it added noise in form of changed
+    files in the source tree and distribution tarballs. It can be
+    ignored with something like "diff -I'^"POT-Creation-Date: '" but
+    it's still a minor annoyance *if* there's not enough value in
+    having the most recent timestamp.
+    
+    Setting DIST_DEPENDS_ON_UPDATE_PO = no means that such forced
+    update won't happen in "make dist" anymore. However, the "mydist"
+    target will use xz.pot-update target which is the same target that
+    is run when xz.pot doesn't exist at all yet. Thus "mydist" will
+    ensure that the translations are up to date, without noise from
+    changes that would affect only the POT-Creation-Date line.
+    
+    Note that po4a always uses msgmerge with --update, so POT-Creation-Date
+    in the man page translations is never the only change in .po files.
+    In that sense this commit makes the message translations behave more
+    similarly to the man page translations.
+    
+    Distribution tarballs will still have non-reproducible POT-Creation-Date
+    in po/xz.pot and po4a/xz-man.pot but those are just two files. Even they
+    could be made reproducible from a Git timestamp if desired.
+    
+    (cherry picked from commit 9284f1aea31f0eb23e2ea72f7218b271e2234762)

-    liblzma: #define lzma_attr_visibility_hidden in common.h.
+    po4a/update-po: Disable wrapping in .pot and .po files
     
-    In ELF shared libs:
+    The .po files from the Translation Project come with unwrapped
+    strings so this matches it.
     
-    -fvisibility=hidden affects definitions of symbols but not
-    declarations.[*] This doesn't affect direct calls to functions
-    inside liblzma as a linker can replace a call to lzma_foo@plt
-    with a call directly to lzma_foo when -fvisibility=hidden is used.
-    
-    [*] It has to be like this because otherwise every installed
-        header file would need to explictly set the symbol visibility
-        to default.
+    This may reduce the noise in diffs too. When the beginning of
+    a paragraph had changed, the rest of the lines got rewrapped
+    in msgsid. Now it's just one very long line that changes when
+    a paragraph has been edited.
     
-    When accessing extern variables that aren't defined in the
-    same translation unit, compiler assumes that the variable has
-    the default visibility and thus indirection is needed. Unlike
-    function calls, linker cannot optimize this.
+    The --add-location=file option was removed as redundant. The line
+    numbers don't exist in the .pot file due to --porefs file and thus
+    they cannot get copied to the .po files either.
     
-    Using __attribute__((__visibility__("hidden"))) with the extern
-    variable declarations tells the compiler that indirection isn't
-    needed because the definition is in the same shared library.
-    
-    About 15+ years ago, someone told me that it would be good if
-    the CRC tables would be defined in the same translation unit
-    as the C code of the CRC functions. While I understood that it
-    could help a tiny amount, I didn't want to change the code because
-    a separate translation unit for the CRC tables was needed for the
-    x86 assembly code anyway. But when visibility attributes are
-    supported, simply marking the extern declaration with the
-    hidden attribute will get identical result. When there are only
-    a few affected variables, this is trivial to do. I wish I had
-    understood this back then already.

-    liblzma: Refer to MinGW-w64 instead of MinGW in the API headers.
+    Update contact info in README
     
-    MinGW (formely a MinGW.org Project, later the MinGW.OSDN Project
-    at <https://osdn.net/projects/mingw/>) has GCC 9.2.0 as the
-    most recent GCC package (released 2021-02-02). The project might
-    still be alive but majority of people have switched to MinGW-w64.
-    Thus it seems clearer to refer to MinGW-w64 in our API headers too.
-    Building with MinGW is likely to still work but I haven't tested it
-    in the recent years.

-    CMake/Windows: Fix the import library filename.
+    CMake: Add manual support for 32-bit x86 assembly files
     
-    Both PREFIX and IMPORT_PERFIX have to be set to "" to get
-    liblzma.dll and liblzma.dll.a.
+    One has to pass -DENABLE_X86_ASM=ON to cmake to enable the
+    CRC assembly code. Autodetection isn't done. Looking at
+    CMAKE_SYSTEM_PROCESSOR might not work as it comes from uname
+    unless cross-compilation is done using a CMake toolchain file.
+    
+    On top of this, if the code is run on modern processors that support
+    the CLMUL instruction, then the C code should be faster (but then
+    one should also be using a x86-64 build if possible).
+    
+    (cherry picked from commit 24387c234b4eed1ef9a7eaa107391740b4095568)

-    CMake: Don't shadow the cache entry ENABLE_THREADS with a normal variable.
+    CMake: Rename USE_DOXYGEN to ENABLE_DOXYGEN
     
-    Using set(ENABLE_THREADS "posix") is confusing because it sets
-    a new normal variable and leaves the cache entry with the same
-    name unchanged. The intent wasn't to change the cache entry so
-    this switches to a different variable name.
+    It's more consistent with the other option() uses.

+    The po4a directory is in EXTRA_DIST and thus all files there

-    CMake: Fix Windows build with Clang/LLVM 17.
+    Tests: Make test_compress.sh more flexible
     
-    llvm-windres 17.0.0 has more accurate emulation of GNU windres, so
-    the hack for GNU windres must now be used with llvm-windres too.
+    Add a new optional second argument: directory of the xz and xzdec
+    executables. This is need with the CMake build where the binaries
+    end up in the top-level build directory.
     
-    LLVM 16.0.6 has the old behavior and there likely won't be more
-    16.x releases. So we can simply check for >= 17.0.0.
+    If ../config.h doesn't exist, assume that all encoders and decoders
+    are available. This will make this script usable from CMake in the
+    most common build configuration.
     
-    The workaround must not be used with Clang that is acting in
-    MSVC mode. This checks for the known environments that need
-    the workaround instead of using "NOT MSVC".
+    NOTE: Since the existence of ../config.h is checked, the working
+    directory of the test script must be a subdir in the build tree!
+    Otherwise ../config.h would look outside the build tree.
     
-    See also:
-    https://github.com/llvm/llvm-project/commit/2bcc0fdc58a220cb9921b47ec8a32c85f2511a47
+    Use the default check type instead of forcing CRC32 or CRC64.
+    Now the script doesn't need to check if CRC64 is available.
+    
+    (cherry picked from commit ac3222d2cb1ff3a15eb6d58f9ea9bc78e8bc3bb2)

-    Build: Silence Autoconf warning.
+    liblzma: Fix white space
     
-    There was a use of AC_COMPILE_IFELSE that didn't use
-    AC_LANG_SOURCE and Autoconf warned about this. The omission
-    had been intentional but it turned out that this didn't do
-    what I thought it would.
-    
-    Autoconf 2.71 manual gives an impression that AC_LANG_SOURCE
-    inserts all #defines that have been made with AC_DEFINE so
-    far (confdefs.h). The idea was that omitting AC_LANG_SOURCE
-    would mean that only the exact code included in the
-    AC_COMPILE_IFELSE call would be compiled.
-    
-    With C programs this is not true: the #defines get added without
-    AC_LANG_SOURCE too. There seems to be no neat way to avoid this.
-    Thus, with the C language at least, adding AC_LANG_SOURCE makes
-    no other difference than silencing a warning from Autoconf. The
-    generated "configure" remains identical. (Docs of AC_LANG_CONFTEST
-    say that the #defines have been inserted since Autoconf 2.63b and
-    that AC_COMPILE_IFELSE uses AC_LANG_CONFTEST. So the behavior is
-    documented if one also reads the docs of macros that one isn't
-    calling directly.)
+    Thanks to xx on #tukaani.
     
-    Any extra code, including #defines, can cause problems for
-    these two tests because these tests must use -Werror.
-    CC=clang CFLAGS=-Weverything is the most extreme example.
-    It enables -Wreserved-macro-identifier which warns about
-    It's possible to write a test file that passes -Weverything but
-    it becomes impossible when Autoconf inserts confdefs.h.
-    
-    So this commit adds AC_LANG_SOURCE to silence Autoconf warnings.
-    A different solution is needed for -Werror tests.

-    xz: Windows: Don't (de)compress to special files like "con" or "nul".
+    xz: Simplify the memory usage scaling code
     
-    Before this commit, the following writes "foo" to the
-    console and deletes the input file:
+    This is closer to what it was before the --filtersX support was added,
+    just extended to support for scaling all filter chains. The method
+    before this commit was an extended version of the original too but
+    it was done in a more complex way for no clear reason. In case of
+    an error, the complex version printed fewer informative messages
+    (a good thing) but it's not a sigificant benefit.
     
-        echo foo | xz > con_xz
-        xz --suffix=_xz --decompress con_xz
+    In the limit is too low even for single-threaded mode, the required
+    amount of memory is now reported like in 5.4.x instead of like in
+    5.5.1alpha - 5.6.1 which showed the original non-scaled usage. It
+    had been a FIXME in the old code but it's not clear what message
+    makes the most sense.
     
-    It cannot happen without --suffix because names like con.xz
-    are also special and so attempting to decompress con.xz
-    (or compress con to con.xz) will already fail when opening
-    the input file.
-    
-    Similar thing is possible when compressing. The following
-    writes to "nul" and the input file "n" is deleted.
-    
-        echo foo | xz > n
-        xz --suffix=ul n
-    
-    Now xz checks if the destination is a special file before
-    continuing. DOS/DJGPP version had a check for this but
-    Windows (and OS/2) didn't.

-    This commit also moves all other function attributes to

+    xz: Rename filters_index to chain_num
     
-    liblzma's lzma_alloc() and lzma_alloc_zero() would be
-    correct uses most of the time but custom allocators
-    may use a memory pool or otherwise hold the pointer
-    so aliasing issues could happen in theory.
+    The reason is the same as in bd0782c1f13e52cd0fd8415208e30e47004a4c68.
     
-    The xstrdup() case likely was correct but I removed it anyway.
-    Now there are no __malloc__ attributes left in the code.
-    The allocations aren't in hot paths so this should make
-    no practical difference.

-    CMake: Fix time.h checks not running on second CMake run.
+    xz: Rename "filters" to "chains"
     
-    If CMake was configured more than once, HAVE_CLOCK_GETTIME and
-    HAVE_CLOCK_MONOTONIC would not be set as compile definitions. The check
-    for librt being needed to provide HAVE_CLOCK_GETTIME was also
-    simplified.
+    The convention is that
+    
+        lzma_filter filters[LZMA_FILTERS_MAX + 1];
+    
+    contains the filters of a single filter chain.
+    It was so here as well before the commit
+    d6af7f347077b22403133239592e478931307759.
+    It changes "filters" to a ten-element array of filter chains.
+    It's clearer to call this array-of-arrays "chains".
+    
+    This also renames "filter_idx" to "chain_idx" which is used
+    as an index as in chains[chain_idx].
+

-    liblzma: Update assert in vli_ceil4().
+    xz: Update a comment and initialization of filters_used_mask
     
-    The argument to vli_ceil4() should always guarantee the return value
-    is also a valid lzma_vli. Thus the highest three valid lzma_vli values
-    are invalid arguments. All uses of the function ensure this so the
-    assert is updated to match this.

-    liblzma: Add overflow check for Unpadded size in lzma_index_append().
+    xz: parse_block_list: Edit integer type casting
     
-    This was not a security bug since there was no path to overflow
-    UINT64_MAX in lzma_index_append() or when it calls index_file_size().
-    The bug was discovered by a failing assert() in vli_ceil4() when called
-    from index_file_size() when unpadded_sum (the sum of the compressed size
-    of current Stream and the unpadded_size parameter) exceeds LZMA_VLI_MAX.
-    
-    Previously, the unpadded_size parameter was checked to be not greater
-    than UNPADDED_SIZE_MAX, but no check was done once compressed_base was
-    added.
-    
-    This could not have caused an integer overflow in index_file_size() when
-    called by lzma_index_append(). The calculation for file_size breaks down
-    into the sum of:
-    
-    - Compressed base from all previous Streams
-    - 2 * LZMA_STREAM_HEADER_SIZE (size of the current Streams header and
-      footer)
-    - stream_padding (can be set by lzma_index_stream_padding())
-    - Compressed base from the current Stream
-    - Unpadded size (parameter to lzma_index_append())
-    
-    The sum of everything except for Unpadded size must be less than
-    LZMA_VLI_MAX. This is guarenteed by overflow checks in the functions
-    that can set these values including lzma_index_stream_padding(),
-    lzma_index_append(), and lzma_index_cat(). The maximum value for
-    Unpadded size is enforced by lzma_index_append() to be less than or
-    equal UNPADDED_SIZE_MAX. Thus, the sum cannot exceed UINT64_MAX since
-    LZMA_VLI_MAX is half of UINT64_MAX.
-    
-    Thanks to Joona Kannisto for reporting this.

-    The Autotools build allows win95 threads and --enable-small together now
-    if the compiler supports __attribute__((__constructor__)).
+    opt_mode == MODE_COMPRESS isn't possible when HAVE_ENCODERS isn't
+    defined. Thus, when *encoding*, the message about *decoder* memory
+    usage is possible to show only when both encoder and decoder have
+    been built.
+

-    Build: Conditionally allow win95 threads and --enable-small.
+    debug/translation.bash: Remove an outdated test command
     
-    When the compiler supports __attribute__((__constructor__))
-    mythread_once() is never used, even with --enable-small. A configuration
-    with win95 threads and --enable-small will compile and be thread safe so
-    it can be allowed.
+    Since 5.3.5beta, "xz --lzma2=mf=bt4,nice=2" works even though bt4 needs
+    at least nice=4. It is rounded up internally by liblzma when needed.
     
-    This isn't a very common configuration since MSVC does not support
-    __attribute__((__constructor__)), but MINGW32 and CLANG32 environments
-    for MSYS2 can use win95 threads and have
-    __attribute__((__constructor__)) support.

-    mythread.h: Disable signal functions in builds targeting Wasm + WASI.
+    Update INSTALL about MINIX 3
     
-    signal.h in WASI SDK doesn't currently provide sigprocmask()
-    or sigset_t. liblzma doesn't need them so this change makes
-    liblzma and xzdec build against WASI SDK. xz doesn't build yet
-    and the tests don't either as tuktest needs setjmp() which
-    isn't (yet?) implemented in WASI SDK.
+    The latest stable is 3.3.0 and it's from 2014.
+    Don't mention the older versions in INSTALL.
+    3.3.0 ships with Clang already.
     
-    Closes: https://github.com/tukaani-project/xz/pull/57
-    See also: https://github.com/tukaani-project/xz/pull/56
+    Testing with 3.4.0beta6 shows that tuklib_physmem
+    works too so omit comments about that from INSTALL.
+    Visibility warnigns weren't a problem either.
     
-    (The original commit was edited a little by Lasse Collin.)
+    Thus it's enough to mention the need for --disable-threads
+    as configure doesn't autodetect the lack of pthreads.

-    CMake: Conditionally allow the creation of broken symlinks.
+    ci: add SPDX headers
     
-    The CMake build will try to create broken symlinks on Unix and Unix-like
-    platforms. Cygwin and MSYS2 are Unix-like, but may not be able to create
-    broken symlinks. The value of the CYGWIN or MSYS environment variables
-    determine if broken symlinks are valid.
+    I've checked over each of these and they're straightforward applications
+    of the relevant Github Actions.
     
-    The default for MSYS2 does not allow for broken symlinks, so the CMake
-    build has been broken for MSYS2 since commit
-    80a1a8bb838842a2be343bd88ad1462c21c5e2c9.
+    (cherry picked from commit 9a6761aa35ed84d30bd2fda2333a4fdf3f46ecdc)

-    liblzma: Prevent an empty translation unit in Windows builds.
+    codespell: Ignore the THANKS file and debbugs.gnu.org URL
     
-    To workaround Automake lacking Windows resource compiler support, an
-    empty source file is compiled to overwrite the resource files for static
-    library builds. Translation units without an external declaration are
-    not allowed by the C standard and result in a warning when used with
-    -Wempty-translation-unit (Clang) or -pedantic (GCC).
+    This way "codespell -i 0" is silent.
+    
+    This is the first commit from
+    https://github.com/tukaani-project/xz/pull/93
+    with trivial edits by Lasse Collin.
+

-    Tests: Add ARM64 filter test to test_compress.sh.
+    xzdec: Support Landlock ABI version 4
+    
+    This was added to xz in 02e3505991233901575b7eabc06b2c6c62a96899
+    but I forgot to do the same in xzdec.
+    
+    The Landlock sandbox in xzdec could be stricter as now it's
+    active only for the last file being decompressed. In xz,
+    read-only sandbox is used for multi-file case. On the other hand,
+    xz doesn't go to the strictest mode when processing the last file
+    when more than one file was specified; xzdec does.
+    
+    (cherry picked from commit 3334c71d3d4294a4f6569df3ba9bcf2443dfa501)

-    xz: Translate the second "%s: " in message.c since French needs "%s : ".
+    CMake: Keep the build working if the "tests" directory is missing
     
-    This string is used to print a filename when using "xz -v" and
-    stderr isn't a terminal.
+    This moves the tests section as is from CMakeLists.txt into
+    tests/tests.cmake. CMakeLists.txt now includes tests/tests.cmake
+    if the latter file exists.
+    
+    Now it's possible to delete the whole "tests" directory and
+    building with CMake will still work normally, just without
+    the tests. This way the tests are readily available for those
+    who want them, and those who won't run the tests anyway have
+    a straightforward way to ensure that nothing from the "tests"
+    directory can affect the build process.

-    liblzma: Prevent warning for MSYS2 Windows build.
-    
-    In lzma_memcmplen(), the <intrin.h> header file is only included if
-    _MSC_VER and _M_X64 are both defined but _BitScanForward64() was
-    previously used if _M_X64 was defined. GCC for MSYS2 defines _M_X64 but
-    not _MSC_VER so _BitScanForward64() was used without including
-    <intrin.h>.
+    Tests: test_index: Test lzma_index_buffer_decode() more
     
-    Now, lzma_memcmplen() will use __builtin_ctzll() for MSYS2 GCC builds as
-    expected.

-    Docs: Add a new section to INSTALL for Tests.
+    Tests: test_index: Test that *i = NULL is done on LZMA_PROG_ERROR
     
-    The new Tests section describes basic information about the tests, how
-    to run them, and important details when cross compiling. We have had a
-    few questions about how to compile the tests without running them, so
-    hopefully this information will help others with the same question in the
-    future.
+    On LZMA_DATA_ERROR from lzma_index_buffer_decode(), *i = NULL was
+    already done but this adds a test for that case too.

-    Tests: Improve feature testing for skipping.
+    Tests: test_index: Make it clear that my_alloc() has no integer overflows
     
-    Fixed a bug where test_compress_* would all fail if arm64 or armthumb
-    filters were enabled for compression but arm was disabled. Since the
-    grep tests only checked for "define HAVE_ENCODER_ARM", this would match
-    on HAVE_ENCODER_ARM64 or HAVE_ENCODER_ARMTHUMB.
+    liblzma guarantees that the product of the allocation size arguments
+    will fit in size_t.
     
-    Now the config.h feature test requires " 1" at the end to prevent the
-    prefix problem. have_feature() was also updated for this even though
-    there were known current bugs affecting it. This is just in case future
-    features have a similar prefix problem.

-    Tests: Fix memory leaks in test_block_header.
+    Tests: test_index: Edit comments and white space
     
-    test_block_header was not properly freeing the filter options between
-    calls to lzma_block_header_decode(). The memory leaks were discovered by
-    using -fsanitize=address with GCC.
+    (cherry picked from commit 2524fcf2b68b662035437cee8edbe80067c0c240)

-    liblzma: Prevent uninitialzed warning in mt stream encoder.
+    liblzma: index_decoder: Fix missing initializations on LZMA_PROG_ERROR
     
-    This change only impacts the compiler warning since it was impossible
-    for the wait_abs struct in stream_encode_mt() to be used before it was
-    initialized since mythread_condtime_set() will always be called before
-    mythread_cond_timedwait().
+    If the arguments to lzma_index_decoder() or lzma_index_buffer_decode()
+    were such that LZMA_PROG_ERROR was returned, the lzma_index **i
+    argument wasn't touched even though the API docs say that *i = NULL
+    is done if an error occurs. This obviously won't be done even now
+    if i == NULL but otherwise it is best to do it due to the wording
+    in the API docs.
     
-    Since the mythread.h code is different between the POSIX and
-    Windows versions, this warning was only present on Windows builds.
+    In practice this matters very little: The problem can occur only
+    if the functions are called with invalid arguments, that is,
+    the calling application must already have a bug.
     
-    Thanks to Arthur S for reporting the warning and providing an initial
-    patch.

-    CMake: Protects against double find_package
+    CMake: Bump maximum policy version to 3.29
     
-    Boost iostream uses `find_package` in quiet mode and then again uses
-    `find_package` with required. This second call triggers a
-    `add_library cannot create imported target "LibLZMA::LibLZMA"
-    because another target with the same name already exists.`
-    
-    This can simply be fixed by skipping the alias part on secondary
-    `find_package` runs.

+    tuklib_integer: Rename bswapXX to byteswapXX
+    
+    The __builtin_bswapXX from GCC and Clang are preferred when
+    they are available. This can allow compilers to emit the x86 MOVBE
+    instruction instead of doing a load + byteswap as two instructions
+    (which would happen if the byteswapping is done in inline asm).
+    
+    bswap16, bswap32, and bswap64 exist in system headers on *BSDs
+    and Darwin. #defining bswap16 on NetBSD results in a warning about
+    macro redefinition. It's safest to avoid this namespace conflict
+    completely.
+    
+    No OS supported by tuklib_integer.h uses byteswapXX names and
+    a web search doesn't immediately find any obvious danger of
+    namespace conflicts. So let's try these still-pretty-short names
+    for the macros.
+    
+    Thanks to Sam James for pointing out the compiler warning on
+    NetBSD 10.0.
+    
+    (cherry picked from commit 4ffc60f32397371769b7d6b5e3ed8626292d58df)

-    tuklib_integer.h: Fix a recent copypaste error in Clang detection.
+    liblzma: Silence a warning from Coverity static analysis
     
-    Wrong line was changed in 7062348bf35c1e4cbfee00ad9fffb4a21aa6eff7.
-    Also, this has >= instead of == since ints larger than 32 bits would
-    work too even if not relevant in practice.
+    It is logical why it cannot know for sure that the value has
+    to be at most 4 if it is less than 16.
+    
+    The x86 filter is based on a very old LZMA SDK version. Newer
+    ones have quite a different implementation for the same filter.

+    Thanks to Sam James.

-    Windows: Include <intrin.h> when needed.
+    Tests: test_lzip_decoder: Tweak coding style and comments
     
-    Legacy Windows did not need to #include <intrin.h> to use the MSVC
-    intrinsics. Newer versions likely just issue a warning, but the MSVC
-    documentation says to include the header file for the intrinsics we use.
-    
-    GCC and Clang can "pretend" to be MSVC on Windows, so extra checks are
-    needed in tuklib_integer.h to only include <intrin.h> when it will is
-    actually needed.

-    tuklib_integer: Use __builtin_clz() with Clang.
-    
-    Clang has support for __builtin_clz(), but previously Clang would
-    fallback to either the MSVC intrinsic or the regular C code. This was
-    discovered due to a bug where a new version of Clang required the
-    <intrin.h> header file in order to use the MSVC intrinsics.
+    Tests: test_lzip_decoder: Remove redundant initializations
     
-    Thanks to Anton Kochkov for notifying us about the bug.

-    CMake: Allows setting thread method.
+    xz: signals: suppress -Wsign-conversion on macOS
     
-    The thread method is now configurable for the CMake build. It matches
-    the Autotools build by allowing ON (pick the best threading method),
-    OFF (no threading), posix, win95, and vista. If both Windows and
-    posix threading are both available, then ON will choose Windows
-    threading. Windows threading will also not use:
+    On macOS, we get:
+    ```
+    signals.c: In function 'signals_init':
+    signals.c:76:17: error: conversion to 'sigset_t' {aka 'unsigned int'} from 'int' may change the sign of the result [-Werror=sign-conversion]
+       76 |                 sigaddset(&hooked_signals, sigs[i]);
+          |                 ^~~~~~~~~

+    ```
     
-    target_link_libraries(liblzma Threads::Threads)
+    We use `int` for `hooked_signals` but we can't just cast to whatever
+    `sigset_t` is because `sigset_t` is an opaque type. It's an unsigned int
+    on macOS. On macOS, `sigaddset` is implemented as a macro.
     
-    since on systems like MinGW-w64 it would link the posix threads
-    without purpose.
+    Just suppress -Wsign-conversion for `signals_init` for macOS given
+    there's no real nice way of fixing this.
+

-    Build: Fix --disable-threads breaking the building of shared libs.
+    ci: test Valgrind
     
-    This is broken in the releases 5.2.6 to 5.4.2. A workaround
-    for these releases is to pass EGREP='grep -E' as an argument
-    to configure in addition to --disable-threads.
+    Using `--trace-children=yes` has a trade-off here, as it makes
+    `test_scripts.sh` pretty slow when calling various non-xz utilities.
     
-    The problem appeared when m4/ax_pthread.m4 was updated in
-    the commit 6629ed929cc7d45a11e385f357ab58ec15e7e4ad which
-    introduced the use of AC_EGREP_CPP. AC_EGREP_CPP calls
-    AC_REQUIRE([AC_PROG_EGREP]) to set the shell variable EGREP
-    but this was only executed if POSIX threads were enabled.
-    Libtool code also has AC_REQUIRE([AC_PROG_EGREP]) but Autoconf
-    omits it as AC_PROG_EGREP has already been required earlier.
-    Thus, if not using POSIX threads, the shell variable EGREP
-    would be undefined in the Libtool code in configure.
+    But I also feel like it's not useless to have Valgrind used there and it's
+    not easy to exclude Valgrind just for that one test...
     
-    ax_pthread.m4 is fine. The bug was in configure.ac which called
-    AX_PTHREAD conditionally in an incorrect way. Using AS_CASE
-    ensures that all AC_REQUIREs get always run.
+    I did consider using AX_VALGRIND_CHECK [0][1] but I couldn't get it working
+    immediately with some conditionally-built tests and I wondered if it was
+    worth spending time on at least while we're debating xz's future build
+    system situation.
     
-    Thanks to Frank Busse for reporting the bug.

-    Thanks to Christian Hesse for reporting the issue.

-    These should have been included in 5.3.2alpha already.
+    This is *NOT* done for security reasons even though the backdoor
+    relied on the ifunc code. Instead, the reason is that in this
+    project ifunc provides little benefits but it's quite a bit of
+    extra code to support it. The only case where ifunc *might* matter
+    for performance is if the CRC functions are used directly by an
+    application. In normal compression use it's completely irrelevant.

-    liblzma: Add set lzma.h as the main page for Doxygen documentation.
+    Docs: Update .xz file format specification to 1.2.1.
     
-    The \mainpage command is used in the first block of comments in lzma.h.
-    This changes the previously nearly empty index.html to use the first
-    comment block in lzma.h for its contents.
+    This only reverts the XZ URL changes.
     
-    lzma.h is no longer documented separately, but this is for the better
-    since lzma.h only defined a few macros that users do not need to use.
-    The individual API header files all have a disclaimer that they should
-    not be #included directly, so there should be no confusion on the fact
-    that lzma.h should be the only header used by applications.
-    
-    Additionally, the note "See ../lzma.h for information about liblzma as
-    a whole." was removed since lzma.h is now the main page of the
-    generated HTML and does not have its own page anymore. So it would be
-    confusing in the HTML version and was only a "nice to have" when
-    browsing the source files.

-    Build: Create doxygen/update-doxygen script.
-    
-    This is a helper script to generate the Doxygen documentation. It can be
-    run in 'liblzma' or 'internal' mode by setting the first argument. It
-    will default to 'liblzma' mode and only generate documentation for the
-    liblzma API header files.
+    xzdec: Tweak coding style and comments.
     
-    The helper script will be run during the custom mydist hook when we
-    create releases. This hook already alters the source directory, so its
-    fine to do it here too. This way, we can include the Doxygen generated
-    files in the distrubtion and when installing.
-    
-    In 'liblzma' mode, the JavaScript is stripped from the .html files and
-    the .js files are removed. This avoids license hassle from jQuery and
-    other libraries that Doxygen 1.9.6 puts into jquery.js in minified form.
+    (cherry picked from commit 2739db981023373a2ddabc7b456c7e658bb4f582)

-    Build: Install Doxygen docs and include in distribution if generated.
-    
-    Added a install-data-local target to install the Doxygen documentation
-    only when it has been generated. In order to correctly remove the docs,

-    Doxygen: Refactor Doxyfile.in to doxygen/Doxyfile.
+    CMake: Fix sabotaged Landlock sandbox check.
     
-    Instead of having Doxyfile.in configured by Autoconf, the Doxyfile
-    can have the tags that need to be configured piped into the doxygen
-    command through stdin with the overrides after Doxyfile's contents.
-    
-    Going forward, the documentation should be generated in two different
-    modes: liblzma or internal.
-    
-    liblzma is useful for most users. It is the documentation for just
-    the liblzma API header files. This is the default.
+    It never enabled it.
     
-    internal is for people who want to understand how xz and liblzma work.
-    It might be useful for people who want to contribute to the project.

-    xz: Don't fail if Capsicum is enabled but kernel doesn't support it.
+    Build: Use only the generic symbol versioning with NVIDIA HPC Compiler.
     
-    (This commit combines related commits from the master branch.)
+    This does the previous commit with CMake.
     
-    If Capsicum support is missing from the kernel or xz is being run
-    in an emulator that lacks Capsicum suport, the syscalls will fail
-    and set errno to ENOSYS. Previously xz would display and error and
-    exit, making xz unusable. Now it will check for ENOSYS and run
-    without sandbox support. Other tools like ssh behave similarly.
+    AC_EGREP_CPP uses AC_REQUIRE so the outermost if-commands must
+    be changed to AS_IF to ensure that things wont break some day.
+    See 5a5bd7f871818029d5ccbe189f087f591258c294.
     
-    Displaying a warning for missing Capsicum support was considered
-    but such extra output would quickly become annoying. It would also
-    break test_scripts.sh in "make check".
-    
-    Also move cap_enter() to be the first step instead of the last one.
-    This matches the example in the cap_rights_limit(2) man page. With
-    the current code it shouldn't make any practical difference though.
-    
-    Thanks to Xin Li for the bug report, suggesting a fix, and testing:
-    https://github.com/tukaani-project/xz/pull/43
-    
-    Thanks to Jia Tan for most of the original commits.

-    lzma_lzma_preset() does not guarentee that the lzma_options_lzma are

-    Tests: Small tweak to test-vli.c.
+    liblzma: Fix building with NVHPC (NVIDIA HPC SDK).
     
-    The static global variables can be disabled if encoders and decoders
-    are not built. If they are not disabled and -Werror is used, it will
-    cause an usused warning as an error.
+    NVHPC compiler has several issues that make it impossible to
+    build liblzma:
+      - the compiler cannot handle unions that contain pointers that
+        are not the first members;
+      - the compiler cannot handle the assembler code in range_decoder.h
+        (LZMA_RANGE_DECODER_CONFIG has to be set to zero);
+      - the compiler fails to produce valid code for delta_decode if the
+        vectorization is enabled, which results in failed tests.
+    
+    This introduces NVHPC-specific workarounds that address the issues.
+    
+    (cherry picked from commit 096bc0e3f8fb4bfc4d2f3f64a7f219401ffb4c31)

-    liblzma: Replace '\n' -> newline in filter.h documentation.
+    CMake: Disable symbol versioning on non-glibc Linux.
     
-    The '\n' renders as a newline when the comments are converted to html
-    by Doxygen.
+    This better matches what configure.ac does. For example, musl has
+    only basic symbol versioning support:
+    
+    https://wiki.musl-libc.org/functional-differences-from-glibc.html#Symbol_versioning
+    
+    configure.ac tries to enable symbol versioning only with glibc
+    so now CMake does the same.

-    liblzma: Improve documentation in filter.h.
+    Build: Let the users override the symbol versioning variant.
     
-    All functions now explicitly specify parameter and return values.
-    The notes and code annotations were moved before the parameter and
-    return value descriptions for consistency.
+    There are cases when the users want to decide themselves whether
+    they want to have the generic (even on GNU/Linux) or the linux
+    (even if we do not recommend that) symbol versioning variant.
+    The former might be needed to circumvent compiler issues (i.e.
+    the compiler does not support all features that are required
+    for the linux versioning), the latter might help in overriding
+    the assumptions made in the configure script.
     
-    Also, the description above lzma_filter_encoder_is_supported() about
-    not being able to list available filters was removed since
-    lzma_str_list_filters() will do this.
+    (cherry picked from commit f56ed6fac6619b56b005878d3b5210e2f0d721c0)

-    liblzma: Avoid null pointer + 0 (undefined behavior in C).
+    Remove the backdoor found in 5.6.0 and 5.6.1 (CVE-2024-3094).
     
-    In the C99 and C17 standards, section 6.5.6 paragraph 8 means that
-    adding 0 to a null pointer is undefined behavior. As of writing,
-    "clang -fsanitize=undefined" (Clang 15) diagnoses this. However,
-    I'm not aware of any compiler that would take advantage of this
-    when optimizing (Clang 15 included). It's good to avoid this anyway
-    since compilers might some day infer that pointer arithmetic implies
-    that the pointer is not NULL. That is, the following foo() would then
-    unconditionally return 0, even for foo(NULL, 0):
+    While the backdoor was inactive (and thus harmless) without inserting
+    a small trigger code into the build system when the source package was
+    created, it's good to remove this anyway:
     
-        void bar(char *a, char *b);
+      - The executable payloads were embedded as binary blobs in
+        the test files. This was a blatant violation of the
+        Debian Free Software Guidelines.
     
-        int foo(char *a, size_t n)
-        {
-            bar(a, a + n);
-            return a == NULL;
-        }
+      - On machines that see lots bots poking at the SSH port, the backdoor
+        noticeably increased CPU load, resulting in degraded user experience
+        and thus overwhelmingly negative user feedback.
     
-    In contrast to C, C++ explicitly allows null pointer + 0. So if
-    the above is compiled as C++ then there is no undefined behavior
-    in the foo(NULL, 0) call.
+      - The maintainer who added the backdoor has disappeared.
     
-    To me it seems that changing the C standard would be the sane
-    thing to do (just add one sentence) as it would ensure that a huge
-    amount of old code won't break in the future. Based on web searches
-    it seems that a large number of codebases (where null pointer + 0
-    occurs) are being fixed instead to be future-proof in case compilers
-    will some day optimize based on it (like making the above foo(NULL, 0)
-    return 0) which in the worst case will cause security bugs.
+      - Backdoors are bad for security.
     
-    Some projects don't plan to change it. For example, gnulib and thus
-    many GNU tools currently require that null pointer + 0 is defined:
+    This reverts the following without making any other changes:
     
-        https://lists.gnu.org/archive/html/bug-gnulib/2021-11/msg00000.html
+    6e636819 Tests: Update two test files.
+    a3a29bbd Tests: Test --single-stream can decompress bad-3-corrupt_lzma2.xz.
+    0b4ccc91 Tests: Update RISC-V test files.
+    8c9b8b20 liblzma: Fix typos in crc32_fast.c and crc64_fast.c.
+    82ecc538 liblzma: Fix false Valgrind error report with GCC.
+    cf44e4b7 Tests: Add a few test files.
+    3060e107 Tests: Use smaller dictionary size in RISC-V test files.
+    e2870db5 Tests: Add two RISC-V Filter test files.
     
-        https://www.gnu.org/software/gnulib/manual/html_node/Other-portability-assumptions.html
+    The RISC-V test files also have real content that tests the filter
+    but the real content would fit into much smaller files. A generator
+    program would need to be available as well.
     
-    In XZ Utils null pointer + 0 issue should be fixed after this
-    commit. This adds a few if-statements and thus branches to avoid
-    null pointer + 0. These check for size > 0 instead of ptr != NULL
-    because this way bugs where size > 0 && ptr == NULL will likely
-    get caught quickly. None of them are in hot spots so it shouldn't
-    matter for performance.
-    
-    A little less readable version would be replacing
-    
-        ptr + offset
-    
-    with
-    
-        offset != 0 ? ptr + offset : ptr
-    
-    or creating a macro for it:
-    
-        #define my_ptr_add(ptr, offset) \
-                ((offset) != 0 ? ((ptr) + (offset)) : (ptr))
-    
-    Checking for offset != 0 instead of ptr != NULL allows GCC >= 8.1,
-    Clang >= 7, and Clang-based ICX to optimize it to the very same code
-    as ptr + offset. That is, it won't create a branch. So for hot code
-    this could be a good solution to avoid null pointer + 0. Unfortunately
-    other compilers like ICC 2021 or MSVC 19.33 (VS2022) will create a
-    branch from my_ptr_add().
-    
-    Thanks to Marcin Kowalczyk for reporting the problem:
-    https://github.com/tukaani-project/xz/issues/36
+    Thanks to Andres Freund for finding and reporting it and making
+    it public quickly so others could act without a delay.

-    Build: Use only the generic symbol versioning on MicroBlaze.
-    
-    On MicroBlaze, GCC 12 is broken in sense that
-    __has_attribute(__symver__) returns true but it still doesn't
-    support the __symver__ attribute even though the platform is ELF
-    and symbol versioning is supported if using the traditional
-    __asm__(".symver ...") method. Avoiding the traditional method is
-    good because it breaks LTO (-flto) builds with GCC.
+    Tests: Update RISC-V test files.
     
-    See also: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101766
-    
-    For now the only extra symbols in liblzma_linux.map are the
-    compatibility symbols with the patch that spread from RHEL/CentOS 7.
-    These require the use of __symver__ attribute or __asm__(".symver ...")
-    in the C code. Compatibility with the patch from CentOS 7 doesn't
-    seem valuable on MicroBlaze so use liblzma_generic.map on MicroBlaze
-    instead. It doesn't require anything special in the C code and thus
-    no LTO issues either.
-    
-    An alternative would be to detect support for __symver__
-    attribute in configure.ac and CMakeLists.txt and fall back
-    to __asm__(".symver ...") but then LTO would be silently broken
-    on MicroBlaze. It sounds likely that MicroBlaze is a special
-    case so let's treat it as a such because that is simpler. If
-    a similar issue exists on some other platform too then hopefully
-    someone will report it and this can be reconsidered.
-    
-    (This doesn't do the same fix in CMakeLists.txt. Perhaps it should
-    but perhaps CMake build of liblzma doesn't matter much on MicroBlaze.
-    The problem breaks the build so it's easy to notice and can be fixed
-    later.)
-    
-    Thanks to Vincent Fazio for reporting the problem and proposing
-    a patch (in the end that solution wasn't used):

-    liblzma: Rename field => member in documentation.
+    liblzma: Fix false Valgrind error report with GCC.
     
-    Also adjusted preset value => preset level.
+    With GCC and a certain combination of flags, Valgrind will falsely
+    trigger an invalid write. This appears to be due to the omission of
+    instructions to properly save, set up, and restore the frame pointer.
+    
+    The IFUNC resolver is a leaf function since it only calls a function
+    that is inlined. So sometimes GCC omits the frame pointer instructions
+    in the resolver unless this optimization is explictly disabled.
+    
+    This fixes https://bugzilla.redhat.com/show_bug.cgi?id=2267598.

-    liblzma: Silence a warning from MSVC.
-    
-    It gives C4146 here since unary minus with unsigned integer
-    is still unsigned (which is the intention here). Doing it
-    with substraction makes it clearer and avoids the warning.
-    
-    Thanks to Nathan Moinvaziri for reporting this.
+    liblzma: Fix a typo in a comment in the RISC-V filter.

-    Standardizing each function to always specify parameters and return

-    function description.
-    
-    A few small things were reworded and long sentences broken up.
+    Thanks to Sam James for determining this was the attribute needed to
+    workaround the GCC bug and for his version of the patch in Gentoo.

-
-    liblzma: Improve documentation in check.h.
+    Using __attribute__((__no_profile_instrument_function__)) on the ifunc
+    resolver works around a bug in GCC -fprofile-generate:
+    it adds profiling code even to ifunc resolvers which can make
+    the ifunc resolver crash at program startup. This attribute
+    was not introduced until GCC 7 and Clang 13, so ifunc won't
+    be used with prior versions of these compilers.
     
-    All functions now explicitly specify parameter and return values.
-    Also moved the note about SHA-256 functions not being exported to the
-    top of the file.

-    liblzma: Improve documentation in index_hash.h.
+    Now that multi threaded encoding is the default, users do not need to
+    see a warning message everytime the number of threads is reduced. On
+    some machines, this could happen very often. It is not unreasonable for
+    users to need to set double verbose mode to see this kind of
+    information.
     
-    All functions now explicitly specify parameter and return values.
-    Also reworded the description of lzma_index_hash_init() for readability.
+    To see these warning messages -vv or --verbose --verbose must be passed
+    to set xz into the highest possible verbosity mode.
+    
+    These warnings had caused automated testing frameworks to fail when they
+    expected no output to stderr.
+    
+    Thanks to Sebastian Andrzej Siewior for reporting this and for the
+    initial version of the patch.

-    before calling these functions.
+    The previous Linux Landlock feature test assumed that having the

+    Translations: Patch man pages to avoid fuzzy matches.
     
-    Thanks to Rafael Fontenelle.

-    liblzma: Fix documentation in filter.h for lzma_str_to_filters()
+    xzmore: Fix typo in xzmore.1.
     
-    The previous documentation for lzma_str_to_filters() was technically
-    correct, but misleading. lzma_str_to_filters() returns NULL on success,
-    which is in practice always defined to 0. This is the same value as
-    LZMA_OK, but lzma_str_to_filters() does not return lzma_ret so we should
-    be more clear.
+    Thanks to Yuri Chornoivan.

-    tuklib_physmem: Silence warning from -Wcast-function-type on MinGW-w64.
-    
-    tuklib_physmem depends on GetProcAddress() for both MSVC and MinGW-w64
-    to retrieve a function address. The proper way to do this is to cast the
-    return value to the type of function pointer retrieved. Unfortunately,
-    this causes a cast-function-type warning, so the best solution is to
-    simply ignore the warning.
+    Tests: Add MicroLZMA test.

-    Calling coder_set_compression_settings() in list mode with verbose mode

-    unnecessary since the command results in an error and not consistent
-    with other formats like lzma and alone.

-    xz: Use ssize_t for the to-be-ignored return value from write(fd, ptr, 1).
+    Old versions of Clang reported the unsupported function attribute and
+    __crc32d() function as warnings instead of errors, so the feature test
+    passed when it shouldn't have, causing a compile error at build time.
+    -Werror was added to this feature test to fix this. The change is not
+    needed for CMake because check_c_source_compiles() also performs
+    linking and the error is caught then.
     
-    It makes no difference here as the return value fits into an int
-    too and it then gets ignored but this looks better.
+    Thanks to Sebastian Andrzej Siewior for reporting this.

-    Explicitly casting the integer to lzma_check silences the warning.
-    Since such an invalid value is needed in multiple tests, a constant
-    INVALID_LZMA_CHECK_ID was added to tests.h.
+    The Landlock rules didn't allow opening directories for reading:
     
-    The use of 0x1000 for lzma_block.check wasn't optimal as if
-    the underlying type is a char then 0x1000 will be truncated to 0.
-    However, in these test cases the value is ignored, thus even with
-    such truncation the test would have passed.

-    Tests: Silence warnings from -Wsign-conversion.
+        $ xz /usr/bin
+        xz: /usr/bin: Permission denied
     
-    Note that assigning an unsigned int to lzma_check doesn't warn
-    on GNU/Linux x86-64 since the enum type is unsigned on that
-    platform. The enum can be signed on some other platform though
-    so it's best to use enumeration type lzma_check in these situations.
+    The simplest fix was to allow opening directories for reading.
+    While it's a bit silly to allow it solely for the error message,
+    it shouldn't make the sandbox significantly weaker.
+    
+    The single-file use case (like when called from GNU tar) is
+    still as strict as possible: all Landlock restrictions are
+    enabled before (de)compression starts.

-    sysdefs.h: Don't include strings.h anymore.
-    
-    On some platforms src/xz/suffix.c may need <strings.h> for
-    strcasecmp() but suffix.c includes the header when it needs it.
+    Windows: Update windows/README-Windows.txt.
     
-    Unless there is an old system that otherwise supports enough C99
-    to build XZ Utils but doesn't have C89/C90-compatible <string.h>,
-    there should be no need to include <strings.h> in sysdefs.h.
+    It's for binary packages built with windows/build.bash.

-    xz: Include <strings.h> in suffix.c if needed for strcasecmp().
+    Windows: Update windows/build.bash.
     
-    SUSv2 and POSIX.1‐2017 declare only a few functions in <strings.h>.
-    Of these, strcasecmp() is used on some platforms in suffix.c.
-    Nothing else in the project needs <strings.h> (at least if
-    building on a modern system).
+    Support for the old MinGW was dropped. Only MinGW-w64 with GCC
+    is supported now.
     
-    sysdefs.h currently includes <strings.h> if HAVE_STRINGS_H is
-    defined and suffix.c relied on this.
+    The script now supports also cross-compilation from GNU/Linux
+    (tests are not run). MSYS2 and also the old MSYS 1.0.11 work
+    for building on Windows. The i686 and x86_64 toolchains must
+    be in PATH to build both 32-bit and 64-bit versions.
     
-    Note that dos/config.h doesn't #define HAVE_STRINGS_H even though
-    DJGPP does have strings.h. It isn't needed with DJGPP as strcasecmp()
-    is also in <string.h> in DJGPP.
+    Parallel builds are done if "nproc" from GNU coreutils is available.
+    
+    MinGW-w64 runtime copyright information file was renamed from
+    COPYING-Windows.txt to COPYING.MinGW-w64-runtime.txt which
+    is the filename used by MinGW-w64 itself. Its existence
+    is now mandatory, it's checked at the beginning of the script.
+    
+    The file TODO is no longer copied to the package.

-    liblzma: CLMUL CRC64: Work around a bug in MSVC, second attempt.
-    
-    This affects only 32-bit x86 builds. x86-64 is OK as is.
-    
-    I still cannot easily test this myself. The reporter has tested
-    this and it passes the tests included in the CMake build and
-    performance is good: raw CRC64 is 2-3 times faster than the
-    C version of the slice-by-four method. (Note that liblzma doesn't
-    include a MSVC-compatible version of the 32-bit x86 assembly code
-    for the slice-by-four method.)
-    
-    Thanks to Iouri Kharon for figuring out a fix, testing, and
-    benchmarking.

-    Revert "liblzma: CLMUL CRC64: Workaround a bug in MSVC (VS2015-2022)."
+    CMake: Don't assume that -fvisibility=hidden is supported outside Windows.
     
-    This reverts commit 36edc65ab4cf10a131f239acbd423b4510ba52d5.
+    The original code was good enough for supporting GNU/Linux
+    and a few others but it wasn't very portable.
     
-    It was reported that it wasn't a good enough fix and MSVC
-    still produced (different kind of) bad code when building
-    for 32-bit x86 if optimizations are enabled.
-    
-    Thanks to Iouri Kharon.
+    CMake doesn't support Solaris Studio's -xldscope=hidden.
+    If it ever does, things should still work with this commit
+    as Solaris Studio supports not only its own __global but also
+    the GNU C __attribute__((visibility("default"))). Support for the
+    attribute was added in 2007 to Sun Studio 12 compiler version 5.9.

-    
-    XZ Utils 5.2.6 and later source packages were generated using

-    CMake/Windows: Add a workaround for windres from GNU binutils.
+    CMake: Use -O2 instead of -O3 in CMAKE_BUILD_TYPE=Release.
     
-    This is combined from the following commits in the master branch:
-    443dfebced041adc88f10d824188eeef5b5821a9
-    6b117d3b1fe91eb26d533ab16a2e552f84148d47
-    5e34774c31d1b7509b5cb77a3be9973adec59ea0
+    -O3 doesn't seem useful for speed but it makes the code bigger.
+    CMake makes is difficult for users to simply override the
+    optimization level: CFLAGS / CMAKE_C_FLAGS aren't helpful because
+    they go before CMAKE_C_FLAGS_RELEASE. Of course, users can override
+    CMAKE_C_FLAGS_RELEASE directly but then they have to remember to
+    add also -DNDEBUG to disable assertions.
     
-    Thanks to Iouri Kharon for the bug report, the original patch,
-    and testing.
+    This commit changes -O3 to -O2 in CMAKE_C_FLAGS_RELEASE if and only if
+    CMAKE_C_FLAGS_RELEASE cache variable doesn't already exist. So if
+    a custom value is passed on the command line (or reconfiguring an
+    already-configured build), the cache variable won't be modified.

-    Tests: test_filter_flags: Clean up minor issues.
+    CMake: Handle symbol versioning on MicroBlaze specially.
     
-    Here are the list of the most significant issues addressed:
-    - Avoid using internal common.h header. It's not good to copy the
-    constants like this but common.h cannot be included for use outside
-    of liblzma. This is the quickest thing to do that could be fixed later.
-    
-    - Omit the INIT_FILTER macro. Initialization should be done with just
-    regular designated initializers.
-    
-    - Use start_offset = 257 for BCJ tests. It demonstrates that Filter
-    Flags encoder and decoder don't validate the options thoroughly.
-    257 is valid only for the x86 filter. This is a bit silly but
-    not a significant problem in practice because the encoder and
-    decoder initialization functions will catch bad alignment still.
-    Perhaps this should be fixed but it's not urgent and doesn't need
-    to be in 5.4.x.
-    
-    - Various tweaks to comments such as filter id -> Filter ID
+    This is to match configure.ac.

-    CMake: Fix a copypaste error in xzdec Windows resource file handling.
+    CMake: Add test_scripts.sh to the tests.
     
-    It was my mistake. Thanks to Iouri Kharon for the bug report.
+    In contrast to Automake, skipping of this test when decoders
+    are disabled is handled at CMake side instead of test_scripts.sh
+    because CMake-build doesn't create config.h.

-    CMake/Windows: Add resource files to xz.exe and xzdec.exe.
+    CMake: Install scripts.
     
-    The command line tools cannot be built with MSVC for now but
-    they can be built with MinGW-w64.
-    
-    Thanks to Iouri Kharon for the bug report and the original patch.
+    Compared to the Autotools-based build, this has simpler handling
+    for the shell (@POSIX_SHELL@) and extra PATH entry for the scripts
+    (configure has --enable-path-for-scripts=PREFIX). The simpler
+    metho should be enough for non-ancient systems and Solaris.

-    liblzma: CLMUL CRC64: Workaround a bug in MSVC (VS2015-2022).
-    
-    I haven't tested with MSVC myself and there doesn't seem to be
-    information about the problem online, so I'm relying on the bug report.
+    Scripts: Use @PACKAGE_VERSION@ instead of @VERSION@.
     
-    Thanks to Iouri Kharon for the bug report and the patch.
+    PACKAGE_VERSION was already used in liblzma.pc.in.
+    This way only one version @foo@ is used.

-    Build: Require that _mm_set_epi64x() is usable to enable CLMUL support.
+    CMake: Simplify symlink creation and install translated man pages.
     
-    VS2013 doesn't have _mm_set_epi64x() so this way CLMUL gets
-    disabled with VS2013.
+    It helps that cmake_install.cmake doesn't parallelize installation
+    so symlinks can be created so that the target is always known to
+    exist (a requirement on Windows in some cases).
     
-    Thanks to Iouri Kharon for the bug report.
+    This bumps the minimum CMake version from 3.13 to 3.14 to use
+    file(CREATE_LINK ...). It could be made to work on 3.13 by
+    calling "cmake -E create_symlink" but it's uglier code and
+    slower in "make install". 3.14 should be a reasonable version
+    to require nowadays, especially since the Autotools build
+    is still the primary build system for most OSes.

-    Tests: Creates test_index_hash.c
+    CMake: Add support for building and installing xz with translations.
     
-    Tests all API functions exported from index_hash.h. Does not have a
-    dedicated test for lzma_index_hash_end.
+    If gettext tools are available, the .po files listed in po/LINGUAS
+    are converted using msgfmt. This allows building with translations
+    directly from xz.git without Autotools.
+    
+    If gettext tools aren't available, the Autotools-created .gmo files
+    in the "po" directory will be used. This allows CMake-based build
+    to use translations from Autotools-generated tarball.
     
-    [Minor edits were made by Lasse Collin.]
+    If translation support is found (Intl_FOUND) but both the
+    gettext tools and the pre-generated .gmo files are missing,
+    then "make" will fail.

-    liblzma: Remove common.h include from common/index.h.
-    
-    common/index.h is needed by liblzma internally and tests. common.h will
-    include and define many things that are not needed by the tests.
-    
-    Also, this prevents include order problems because both common.h and
-    lzma.h define LZMA_API. On most platforms it results only in a warning
-    but on Windows it would break the build as the definition in common.h
-    must be used only for building liblzma itself.
+    liblzma: Remove commented-out code.

-    liblzma: Replaced hardcoded 0x0 index indicator byte with macro
+    xz: Use stricter pledge(2) and Landlock sandbox.
+    
+    This makes these sandboxing methods stricter when no files are
+    created or deleted. That is, it's a middle ground between the
+    initial sandbox and the strictest single-file-to-stdout sandbox:
+    this allows opening files for reading but output has to go to stdout.

-    Style: Change #if !defined() to #ifndef in mythread.h.
+    xz: Support Landlock ABI version 4.
+    
+    Linux 6.7 added support for ABI version 4 which restricts
+    TCP connections which xz won't need and thus those can be
+    forbidden now. Since the ABI version is handled at runtime,
+    supporting version 4 won't cause any compatibility issues.
+    
+    Note that new enough kernel headers are required to get
+    version 4 support enabled at build time.

-    Build: Add missing stream_decoder_mt.c to .vcxproj files.
+    xz: Move sandboxing code to sandbox.c and improve Landlock sandbox.
     
-    The line in the .vcxproj files for building with was missing in 5.4.0.
-    Thank to Hajin Jang for reporting the issue.
+    Landlock is now always used just like pledge(2) is: first in more
+    permissive mode and later (under certain common conditions) in
+    a strict mode that doesn't allow opening more files.
+    
+    I put pledge(2) first in sandbox.c because it's the simplest API
+    to use and still somewhat fine-grained for basic applications.
+    So it's the simplest thing to understand for anyone reading sandbox.c.

-    xz: Includes <time.h> and <sys/time.h> conditionally in mytime.c.
+    liblzma/rangecoder: Exclude x32 from the x86-64 optimisation.
     
-    Previously, mytime.c depended on mythread.h for <time.h> to be included.
+    The x32 port has a x86-64 ABI in term of all registers but uses only
+    32bit pointer like x86-32. The assembly optimisation fails to compile on
+    x32. Given the state of x32 I suggest to exclude it from the
+    optimisation rather than trying to fix it.

-    liblzma: Includes sys/time.h conditionally in mythread
-    
-    Previously, <sys/time.h> was always included, even if mythread only used
-    clock_gettime. <time.h> is still needed even if clock_gettime is not used
-    though because struct timespec is needed for mythread_condtime.

-    Build: No longer require HAVE_DECL_CLOCK_MONOTONIC to always be set.
-    
-    Previously, if threading was enabled HAVE_DECL_CLOCK_MONOTONIC would always
-    be set to 0 or 1. However, this macro was needed in xz so if xz was not
-    built with threading and HAVE_DECL_CLOCK_MONOTONIC was not defined but
-    HAVE_CLOCK_GETTIME was, it caused a warning during build. Now,
-    HAVE_DECL_CLOCK_MONOTONIC has been renamed to HAVE_CLOCK_MONOTONIC and
-    will only be set if it is 1.
+    Translations: Update the Swedish translation.

-    liblzma: Fix lzma_microlzma_encoder() return value.
-    
-    Using return_if_error on lzma_lzma_lclppb_encode was improper because
-    return_if_error is expecting an lzma_ret value, but
-    lzma_lzma_lclppb_encode returns a boolean. This could result in
-    lzma_microlzma_encoder, which would be misleading for applications.

-    xz: Don't modify argv[].
-    
-    The code that parses --memlimit options and --block-list modified
-    the argv[] when parsing the option string from optarg. This was
-    visible in "ps auxf" and such and could be confusing. I didn't
-    understand it back in the day when I wrote that code. Now a copy
-    is allocated when modifiable strings are needed.
+    liblzma: Add comments.

-    Thanks to Remus-Gabriel Chelu.
+    It's used only for basic bittrees and fixed-size reverse bittree
+    because those showed a clear benefit on x86-64 with GCC and Clang.
+    The other methods were more mixed and thus are commented out but
+    they should be tested on other archs.

-    liblzma: Check for unexpected NULL pointers in block_header_decode().
+    liblzma: LZMA decoder: Optimize loop comparison.
     
-    The API docs gave an impression that such checks are done
-    but they actually weren't done. In practice it made little
-    difference since the calling code has a bug if these are NULL.
-    
-    Thanks to Jia Tan for the original patch that checked for
-    block->filters == NULL.
+    But now it needs one more local variable.

-    liblzma: Use __has_attribute(__symver__) to fix Clang detection.
+    liblzma: Optimize LZ decoder slightly.
     
-    If someone sets up Clang to define __GNUC__ to 10 or greater
-    then symvers broke. __has_attribute is supported by such GCC
-    and Clang versions that don't support __symver__ so this should
-    be much better and simpler way to detect if __symver__ is
-    actually supported.
+    Now extra buffer space is reserved so that repeating bytes for
+    any single match will never need to copy from two places (both
+    the beginning and the end of the buffer). This simplifies
+    dict_repeat() and helps a little with speed.
     
-    Thanks to Tomasz Gajc for the bug report.
+    This seems to reduce .lzma decompression time about 2 %, so
+    with .xz and CRC it could be slightly less. The small things
+    add up still.

-    liblzma: Omit zero-skipping from ARM64 filter.
+    liblzma: LZMA decoder: Get rid of next_state[].
     
-    It has some complicated downsides and its usefulness is more limited
-    than I originally thought. So this change is bad for certain very
-    specific situations but a generic solution that works for other
-    filters (and is otherwise better too) is planned anyway. And this
-    way 7-Zip can use the same compatible filter for the .7z format.
+    It's not completely obvious if this is better in the decoder.
+    It should be good if compiler can avoid creating a branch
+    (like using CMOV on x86).
     
-    This is still marked as experimental with a new temporary Filter ID.
+    This also makes lzma_encoder.c use the new macros.

-    liblzma: Don't be over-specific in lzma_str_to_filters API doc.
+    liblzma: Creates Non-resumable and Resumable modes for lzma_decoder.
+    
+    The new decoder resumes the first decoder loop in the Resumable mode.
+    Then, the code executes in Non-resumable mode until it detects that it
+    cannot guarantee to have enough input/output to decode another symbol.
+    
+    The Resumable mode is how the decoder has always worked. Before decoding
+    every input bit, it checks if there is enough space and will save its
+    location to be resumed later. When the decoder has more input/output,
+    it jumps back to the correct sequence in the Resumable mode code.
+    
+    When the input/output buffers are large, the Resumable mode is much
+    slower than the Non-resumable because it has more branches and is harder
+    for the compiler to optimize since it is in a large switch block.
+    
+    Early benchmarking shows significant time improvement (8-10% on gcc and
+    clang x86) by using the Non-resumable code as much as possible.

-    liblzma: Silence unused variable warning when BCJ filters are disabled.
+    liblzma: Creates separate "safe" range decoder mode.
     
-    Thanks to Jia Tan for the original patch.
+    The new "safe" range decoder mode is the same as old range decoder, but
+    now the default behavior of the range decoder will not check if there is
+    enough input or output to complete the operation. When the buffers are
+    close to fully consumed, the "safe" operations must be used instead. This
+    will improve speed because it will reduce the number of branches needed
+    for most of the range decoder operations.

+    it was never added to po/POTFILES.in so the messages weren't
+    translated. It's a very rarely needed tool so it's not too bad.
     
-    Also update the IRC reference in README as #tukaani was moved
-    to Libera Chat long ago.
+    This also adds src/xz/mytime.c to po/POTFILES.in although there
+    are no translatable strings. It's simpler this way so that it
+    won't be forgotten if strings were ever added to that file.

-    xz: Use lzma_str_from_filters().
+    xzdiff, xzgrep, and xzmore: Rewrite the man pages.
+    
+    The main reason is a kind of silly one:
+    
+    xz-man.pot contains strings from all man pages in XZ Utils.
+    The man pages of xzdiff, xzgrep, and xzmore were under GPLv2
+    and the rest under 0BSD. Thus xz-man.pot contained strings
+    under two licences. po4a creates the translated man pages
+    from the combined 0BSD+GPLv2 xz-man.pot.
+    
+    I haven't liked this mixing in xz-man.pot but the
+    Translation Project requires that all man pages must be
+    in the same .pot file. So a separate xz-man-gpl.pot
+    wasn't an option.
     
-    Two uses: Displaying encoder filter chain when compressing with -vv,
-    and displaying the decoder filter chain in --list -vv.
+    Since these man pages are short, rewriting them was quick enough.
+    Now xz-man.pot is entirely under 0BSD and marking the per-file
+    licenses is simpler.
+    
+    As a bonus, some wording hopefully is now slightly better
+    although it's perhaps a matter of taste.
+    
+    NOTE: In xzgrep.1, the EXIT STATUS section was written by me
+    in the commit d796b6d7fdb8b7238b277056cf9146cce25db604 so that's
+    why that section could be taken as is from the old xzgrep.1.

-    liblzma: Add lzma_str_to_filters, _from_filters, and _list_filters.
+    xzless: Update man page slightly.
     
-    lzma_str_to_filters() uses static error messages which makes
-    them not very precise. It tells the position in the string
-    where an error occurred though which helps quite a bit if
-    applications take advantage of it. Dynamic error messages can
-    be added later with a new flag if it seems important enough.
+    The xz tool can decompress three file formats and xzless
+    has always supported uncompressed files too.

+Date:   2024-02-09 17:20:31 +0200
+
+    Fix SHA-256 authors.
+    
+    The initial commit 5d018dc03549c1ee4958364712fb0c94e1bf2741
+    in 2007 had a comment in sha256.c that the code is based on
+    Crypto++ Library 5.5.1. In 2009 the Authors list in sha256.c
+    and the AUTHORS file was updated with information that the
+    code had come from Crypto++ but via 7-Zip. I know I had viewed
+    7-Zip's SHA-256 code but back then the C code has been identical
+    enough with Crypto++, so I don't why I thought the author info
+    would need that extra step via 7-Zip for this single file.
+    
+    Another error is that I had mixed sha.* and shacal2.* files
+    when checking for author info in Crypto++. The shacal2.* files
+    aren't related to liblzma's sha256.c and thus Kevin Springle's
+    code in Crypto++ isn't either.

-    liblzma: Add LZMA_FILTER_LZMA1EXT to support LZMA1 without end marker.
-    
-    Some file formats need support for LZMA1 streams that don't use
-    the end of payload marker (EOPM) alias end of stream (EOS) marker.
-    So far liblzma API has supported decompressing such streams via
-    lzma_alone_decoder() when .lzma header specifies a known
-    uncompressed size. Encoding support hasn't been available in the API.
-    
-    Instead of adding a new LZMA1-only API for this purpose, this commit
-    adds a new filter ID for use with raw encoder and decoder. The main
-    benefit of this approach is that then also filter chains are possible,
-    for example, if someone wants to implement support for .7z files that
-    use the x86 BCJ filter with LZMA1 (not BCJ2 as that isn't supported
-    in liblzma).
+    Translations: Update the Chinese (simplified) translation.

-    xz: Allow nice_len 2 and 3 even if match finder requires 3 or 4.
-    
-    Now that liblzma accepts these, we avoid the extra check and
-    there's one message less for translators too.

-    liblzma: Allow nice_len 2 and 3 even if match finder requires 3 or 4.
-    
-    That is, if the specified nice_len is smaller than the minimum
-    of the match finder, silently use the match finder's minimum value
-    instead of reporting an error. The old behavior is annoying to users
-    and it complicates xz options handling too.

-    Build: Don't put GNU/Linux-specific symbol versions into static liblzma.
-    
-    It not only makes no sense to put symbol versions into a static library
-    but it can also cause breakage.
-    
-    By default Libtool #defines PIC if building a shared library and
-    doesn't define it for static libraries. This is documented in the
-    Libtool manual. It can be overriden using --with-pic or --without-pic.
-    configure.ac detects if --with-pic or --without-pic is used and then
-    gives an error if neither --disable-shared nor --disable-static was
-    used at the same time. Thus, in normal situations it works to build
-    both shared and static library at the same time on GNU/Linux,
-    only --with-pic or --without-pic requires that only one type of
-    library is built.
-    
-    Thanks to John Paul Adrian Glaubitz from Debian for reporting
-    the problem that occurred on ia64:
-    https://www.mail-archive.com/xz-devel@tukaani.org/msg00610.html

-    liblzma: Refactor to use lzma_filters_free().
-    
-    lzma_filters_free() sets the options to NULL and ids to
-    LZMA_VLI_UNKNOWN so there is no need to do it by caller;
-    the filter arrays will always be left in a safe state.
-    
-    Also use memcpy() instead of a loop to copy a filter chain
-    when it is known to be safe to copy LZMA_FILTERS_MAX + 1
-    (even if the elements past the terminator might be uninitialized).

-    liblzma: Fix invalid free() after memory allocation failure.
-    
-    The bug was in the single-threaded .xz Stream encoder
-    in the code that is used for both re-initialization and for
-    lzma_filters_update(). To trigger it, an application had
-    to either re-initialize an existing encoder instance with
-    lzma_stream_encoder() or use lzma_filters_update(), and
-    then one of the 1-4 tiny allocations in lzma_filters_copy()
-    (called from stream_encoder_update()) must fail. An error
-    was correctly reported but the encoder state was corrupted.
+    liblzma: Only use ifunc in crcXX_fast.c if its needed.
     
-    This is related to the recent fix in
-    f8ee61e74eb40600445fdb601c374d582e1e9c8a which is good but
-    it wasn't enough to fix the main problem in stream_encoder.c.
+    The code was using HAVE_FUNC_ATTRIBUTE_IFUNC instead of CRC_USE_IFUNC.
+    With ARM64, ifunc is incompatible because it requires non-inline
+    function calls for runtime detection.

-    liblzma: Fix infinite loop in LZMA encoder init with dict_size >= 2 GiB.
+    liblzma: Omit CRC tables when not needed with ARM64 optimizations.
     
-    The encoder doesn't support dictionary sizes larger than 1536 MiB.
-    This is validated, for example, when calculating the memory usage
-    via lzma_raw_encoder_memusage(). It is also enforced by the LZ
-    part of the encoder initialization. However, LZMA encoder with
-    LZMA_MODE_NORMAL did an unsafe calculation with dict_size before
-    such validation and that results in an infinite loop if dict_size
-    was 2 << 30 or greater.
+    This is similar to the existing x86-64 CLMUL conditions to omit the
+    tables. They were slightly refactored to improve readability.

-    xz: Refactor duplicate code from hardware_memlimit_mtenc_get().
+    Even though the proper name for the architecture is aarch64, this
+    project uses ARM64 throughout. So the rename is for consistency.
+    
+    Additionally, crc32_arm64.h was slightly refactored for the following
+    changes:
+    
+       * Added MSVC, FreeBSD, and macOS support in
+         is_arch_extension_supported().
+    
+       * crc32_arch_optimized() now checks the size when aligning the
+         buffer.
+    
+       * crc32_arch_optimized() loop conditions were slightly modified to
+         avoid both decrementing the size and incrementing the buffer
+         pointer.
+    
+       * Use the intrinsic wrappers defined in <arm_acle.h> because GCC and
+         Clang name them differently.
+    
+       * Minor spacing and comment changes.

+    liblzma: Refactor crc_common.h.
+    
+    The CRC_GENERIC is now split into CRC32_GENERIC and CRC64_GENERIC, since

+    Build: Add support for ARM64 CRC32 instruction detection.
+    
+    This adds --enable-arm64-crc32/--disable-arm64-crc32 (enabled by
+    default) for using the ARM64 CRC32 instruction. This can be disabled if
+    one knows the binary will never need to run on an ARM64 machine
+    with this instruction extension.

-    Translations: Update the Turkish translation.
+    Speed up CRC32 calculation on ARM64
+    
+    The CRC32 instructions in ARM64 can calculate the CRC32 result
+    for 8 bytes in a single operation, making the use of ARM64
+    instructions much faster compared to the general CRC32 algorithm.
+    
+    Optimized CRC32 will be enabled if ARM64 has CRC extension
+    running on Linux.

-    Revert "liblzma: Simple/BCJ filters: Allow disabling generic BCJ options."
-    
-    This reverts commit 177bdc922cb17bd0fd831ab8139dfae912a5c2b8
-    and also does equivalent change to arm64.c.
+    Move doc/logo/xz-logo.png to "doc" and Doxygen footer to "doxygen".
     
-    Now that ARM64 filter will use lzma_options_bcj, this change
-    is not needed anymore.
+    The footer isn't a complete HTML file so having it in the doxygen
+    directory is a tiny bit clearer.

+    Doxygen: Added the XZ logo and copyright information.
     
-    This has space/tab fixes in filter_*.c and bcj.h too.
+    The PROJECT_LOGO field is now used to include the XZ logo. The footer
+    of each page now lists the copyright information instead of the default
+    footer. The license is also copied to statisfy the copyright and so the
+    link in the documentation can be local.

-    liblzma: Add fast CRC64 for 32/64-bit x86 using SSSE3 + SSE4.1 + CLMUL.
+    xz: Use threaded mode by defaut (as if --threads=0 was used).
     
-    It also works on E2K as it supports these intrinsics.
+    This hopefully does more good than bad:
     
-    On x86-64 runtime detection is used so the code keeps working on
-    older processors too. A CLMUL-only build can be done by using
-    -msse4.1 -mpclmul in CFLAGS and this will reduce the library
-    size since the generic implementation and its 8 KiB lookup table
-    will be omitted.
+      + It's faster by default.
     
-    On 32-bit x86 this isn't used by default for now because by default
-    on 32-bit x86 the separate assembly file crc64_x86.S is used.
-    If --disable-assembler is used then this new CLMUL code is used
-    the same way as on 64-bit x86. However, a CLMUL-only build
-    (-msse4.1 -mpclmul) won't omit the 8 KiB lookup table on
-    32-bit x86 due to a currently-missing check for disabled
-    assembler usage.
+      + Only the threaded compressor creates files that
+        can be decompressed in threaded mode.
     
-    The configure.ac check should be such that the code won't be
-    built if something in the toolchain doesn't support it but
-    --disable-clmul-crc option can be used to unconditionally
-    disable this feature.
+      - Compression ratio is worse, usually not too much though.
+        When it matters, -T1 must be used.
     
-    CLMUL speeds up decompression of files that have compressed very
-    well (assuming CRC64 is used as a check type). It is know that
-    the CLMUL code is significantly slower than the generic code for
-    tiny inputs (especially 1-8 bytes but up to 16 bytes). If that
-    is a real-world problem then there is already a commented-out
-    variant that uses the generic version for small inputs.
+      - Memory usage increases.
     
-    Thanks to Ilya Kurdyukov for the original patch which was
-    derived from a white paper from Intel [1] (published in 2009)
-    and public domain code from [2] (released in 2016).
+      - Scripts that assume single-threaded mode but don't use -T1 will
+        possibly use too much resources, for example, if they run
+        multiple xz processes in parallel to compress multiple files.
     
-    [1] https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/fast-crc-computation-generic-polynomials-pclmulqdq-paper.pdf
-    [2] https://github.com/rawrunprotected/crc
+      - Output from single-threaded and multi-threaded compressors
+        differ but such changes could happen for other reasons too
+        (they just haven't happened since 5.0.0).

-    It didn't do anything. There are only 32-bit x86 assembly files
-    and it feels likely that new files won't be added as intrinsics
-    in C are more portable across toolchains and OSes.

-
-    liblzma: Use __attribute__((__constructor__)) if available.
+    Not all RISC-V processors support fast unaligned access so
+    it's better to read only one byte in the main loop. This can
+    be faster even on x86-64 when compared to reading 32 bits at
+    a time as half the time the address is only 16-bit aligned.
     
-    This uses it for CRC table initializations when using --disable-small.
-    It avoids mythread_once() overhead. It also means that then
-    --disable-small --disable-threads is thread-safe if this attribute
-    is supported.
+    The downside is larger code size on archs that do support
+    fast unaligned access.

+    Tests: Add two RISC-V Filter test files.
+    
+    These test files achieve 100% code coverage in
+    src/liblzma/simple/riscv.c. They contain all of the instructions that
+    should be filtered and a few cases that should not.

-    liblzma: Fix incorrect #ifdef for x86 SSE2 support.
+    Docs: Update .xz file format specification to 1.2.0.
     
-    __SSE2__ is the correct macro for SSE2 support with GCC, Clang,
-    and ICC. __SSE2_MATH__ means doing floating point math with SSE2
-    instead of 387. Often the latter macro is defined if the first
-    one is but it was still a bug.
+    The new RISC-V filter was added to the specification, in addition to
+    updating the specification URL.

-    xz: Add --arm64 to --long-help and omit endianness from ARM(-Thumb).
-    
-    Modern 32-bit ARM in big endian mode use little endian for
-    instruction encoding still, so the filters work on such
-    executables too. It's likely less confusing for users this way.
-    
-    The --arm64 option hasn't been implemented yet (there is
-    --experimental-arm64 but it's different). The --arm64 option
-    is added now anyway because this is the likely result and the
-    strings need to be ready for translators.
+    liblzma: CRC: Remove crc_always_inline, use lzma_always_inline instead.
     
-    Thanks to Jia Tan.
+    Now crc_simd_body() in crc_x86_clmul.h is only called once
+    in a translation unit, we no longer need to be so cautious
+    about ensuring the always-inline behavior.

-    DOS: Update Makefile and config.h to include ARM64 and .lz support.
+    liblzma: Rename arch-specific CRC functions and macros.
+    
+    CRC_CLMUL was split to CRC_ARCH_OPTIMIZED and CRC_X86_CLMUL.
+    CRC_ARCH_OPTIMIZED is defined when an arch-optimized version is used.
+    Currently the x86 CLMUL implementations are the only arch-optimized
+    versions, and these also use the CRC_x86_CLMUL macro to tell when
+    crc_x86_clmul.h needs to be included.
+    
+    is_clmul_supported() was renamed to is_arch_extension_supported().
+    crc32_clmul() and crc64_clmul() were renamed to
+    crc32_arch_optimized() and crc64_arch_optimized().
+    This way the names make sense with arch-specific non-CLMUL
+    implementations as well.

-    Docs: Update INSTALL and also add new prohibited options to PACKAGERS.
+    liblzma: Avoid extern lzma_crc32_clmul() and lzma_crc64_clmul().
+    
+    A CLMUL-only build will have the crcxx_clmul() inlined into
+    lzma_crcxx(). Previously a jump to the extern lzma_crcxx_clmul()
+    was needed. Notes about shared liblzma on ELF platforms:
+    
+      - On platforms that support ifunc and -fvisibility=hidden, this
+        was silly because CLMUL-only build would have that single extra
+        jump instruction of extra overhead.
+    
+      - On platforms that support neither -fvisibility=hidden nor linker
+        version script (liblzma*.map), jumping to lzma_crcxx_clmul()
+        would go via PLT so a few more instructions of overhead (still
+        not a big issue but silly nevertheless).
+    
+    There was a downside with static liblzma too: if an application only
+    needs lzma_crc64(), static linking would make the linker include the
+    CLMUL code for both CRC32 and CRC64 from crc_x86_clmul.o even though
+    the CRC32 code wouldn't be needed, thus increasing code size of the
+    executable (assuming that -ffunction-sections isn't used).
+    
+    Also, now compilers are likely to inline crc_simd_body()
+    even if they don't support the always_inline attribute
+    (or MSVC's __forceinline). Quite possibly all compilers
+    that build the code do support such an attribute. But now
+    it likely isn't a problem even if the attribute wasn't supported.
+    
+    Now all x86-specific stuff is in crc_x86_clmul.h. If other archs
+    The other archs can then have their own headers with their own
+    is_clmul_supported() and crcxx_clmul().
+    
+    Another bonus is that the build system doesn't need to care if
+    crc_clmul.c is needed.
+    
+    is_clmul_supported() stays as inline function as it's not needed
+    when doing a CLMUL-only build (avoids a warning about unused function).

-    liblzma: Add .lz (lzip) decompression support (format versions 0 and 1).
-    
-    Support for format version 0 was removed from lzip 1.18 for some
-    reason. .lz format version 0 files are rare (and old) but some
-    source packages were released in this format, and some people might
-    have personal files in this format too. It's very little extra code
-    to support it along side format version 1 so this commits adds
-    support for both.
-    
-    The Sync Flush marker extentension to the original .lz format
-    version 1 isn't supported. It would require changes to the
-    LZMA decoder itself. Such files are very rare anyway.
-    
-    See the API doc for lzma_lzip_decoder() for more details about
-    the .lz format support.
-    
-    Thanks to Michał Górny for the original patch.
+    Update THANKS.

-    xz: Add comments about stdin and src_st.st_size.
+    It requires fast unaligned access to 64-bit integers
+    and a fast instruction to count leading zeros in
+    a 64-bit integer (__builtin_ctzll()). This perhaps
+    should be enabled on some other archs too.
     
-    "xz -v < regular_file > out.xz" doesn't display the percentage
-    and estimated remaining time because it doesn't even try to
-    check the input file size when input is read from stdin.
-    This could be improved but for now there's just a comment
-    to remind about it.

-    xz: Fix displaying of file sizes in progress indicator in passthru mode.
+    Thanks to Chenxi Mao for the original patch:
+    https://github.com/tukaani-project/xz/pull/75 (the first commit)
+    According to the numbers there, this may improve encoding
+    speed by about 3-5 %.
     
-    It worked for one input file since the counters are zero when
-    xz starts but they weren't reset when starting a new file in
-    passthru mode. For example, if files A, B, and C are one byte each,
-    then "xz -dcvf A B C" would show file sizes as 1, 2, and 3 bytes
-    instead of 1, 1, and 1 byte.
+    This enables the 8-byte method on MSVC ARM64 too which
+    should work but wasn't tested.

-    liblzma: Fix a comment in auto_decoder.c.
+    liblzma: Initialize lzma_lz_encoder pointers with NULL.
+    
+    This fixes the recent change to lzma_lz_encoder that used memzero
+    instead of the NULL constant. On some compilers the NULL constant
+    (always 0) may not equal the NULL pointer (this only needs to guarentee
+    to not point to valid memory address).
+    
+    Later code compares the pointers to the NULL pointer so we must
+    initialize them with the NULL pointer instead of 0 to guarentee
+    code correctness.

-    xz: Initialize the pledge(2) sandbox at the very beginning of main().
+    liblzma: Set all values in lzma_lz_encoder to NULL after allocation.
+    
+    The first member of lzma_lz_encoder doesn't necessarily need to be set
+    to NULL since it will always be set before anything tries to use it.
+    However the function pointer members must be set to NULL since other
+    functions rely on this NULL value to determine if this behavior is
+    supported or not.
+    
+    This fixes a somewhat serious bug, where the options_update() and
+    set_out_limit() function pointers are not set to NULL. This seems to
+    have been forgotten since these function pointers were added many years
+    after the original two (code() and end()).
+    
+    The problem is that by not setting this to NULL we are relying on the
+    memory allocation to zero things out if lzma_filters_update() is called
+    on a LZMA1 encoder. The function pointer for set_out_limit() is less
+    serious because there is not an API function that could call this in an
+    incorrect way. set_out_limit() is only called by the MicroLZMA encoder,
+    which must use LZMA1 where set_out_limit() is always set. Its currently
+    not possible to call set_out_limit() on an LZMA2 encoder at this time.
     
-    It feels better that the initializations are sandboxed too.
-    They don't do anything that the pledge() call wouldn't allow.
+    So calling lzma_filters_update() on an LZMA1 encoder had undefined
+    behavior since its possible that memory could be manipulated so the
+    options_update member pointed to a different instruction sequence.
+    
+    This is unlikely to be a bug in an existing application since it relies
+    on calling lzma_filters_update() on an LZMA1 encoder in the first place.
+    For instance, it does not affect xz because lzma_filters_update() can
+    only be used when encoding to the .xz format.
+    
+    This is fixed by using memzero() to set all members of lzma_lz_encoder
+    to NULL after it is allocated. This ensures this mistake will not occur
+    here in the future if any additional function pointers are added.

-    liblzma: Include cached memory in reported memusage in threaded decoder.
-    
-    This affects lzma_memusage() and lzma_memlimit_set() when used
-    with the threaded decompressor. Now all allocations are reported
-    by lzma_memusage() (so it's not misleading) and lzma_memlimit_set()
-    cannot lower the limit below that value.
+    liblzma: Make parameter names in function definition match declaration.
     
-    The alternative would have been to allow lowering the limit if
-    doing so is possible by freeing the cached memory but since
-    the primary use case of lzma_memlimit_set() is to increase
-    memlimit after LZMA_MEMLIMIT_ERROR this simple approach
-    was selected.
-    
-    The cached memory was always included when enforcing
-    the memory usage limit while decoding.
-    
-    Thanks to Jia Tan.
+    lzma_raw_encoder() and lzma_raw_encoder_init() used "options" as the
+    parameter name instead of "filters" (used by the declaration). "filters"
+    is more clear since the parameter represents the list of filters passed
+    to the raw encoder, each of which contains filter options.

-    xz: Avoid a compiler warning in progress_speed() in message.c.
+    liblzma: Improve lzma encoder init function consistency.
     
-    This should be smaller too since it avoids the string constants.
+    lzma_encoder_init() did not check for NULL options, but
+    lzma2_encoder_init() did. This is more of a code style improvement than
+    anything else to help make lzma_encoder_init() and lzma2_encoder_init()
+    more similar.

-    Windows: Fix mythread_once() macro with Vista threads.
+    Tests: Silence -Wsign-conversion warning on GCC version < 10.
+    
+    Since GCC version 10, GCC no longer complains about simple implicit
+    integer conversions with Arithmetic operators.
+    
+    For instance:
+    
+        uint8_t a = 5;
+        uint32_t b = a + 5;
     
-    Don't call InitOnceComplete() if initialization was already done.
+    Give a warning on GCC 9 and earlier but this:
     
-    So far mythread_once() has been needed only when building
-    with --enable-small. windows/build.bash does this together
-    with --disable-threads so the Vista-specific mythread_once()
-    is never needed by those builds. VS project files or
-    CMake-builds don't support HAVE_SMALL builds at all.
+        uint8_t a = 5;
+        uint32_t b = (a + 5) * 2;
+    
+    Gives a warning with GCC 10+.

-    CMake: Sync tuklib_cpucores.cmake with tuklib_cpucores.m4.
+    Tests: Minor cleanups to OSS-Fuzz files.
+    
+    Most of these fixes are small typos and tweaks. A few were caused by bad
+    advice from me. Here is the summary of what is changed:
+    
+    - Author line edits
     
-    This was forgotten from commit 2611c4d90535652d3eb7ef4a026a6691276fab43.
+    - Small comment changes/additions
+    
+    - Using the return value in the error messages in the fuzz targets'
+      coder initialization code
+    
+    - Removed fuzz_encode_stream.options. This set a max length, which may
+      prevent some worthwhile code paths from being properly exercised.
+    
+    - Removed the max_len option from fuzz_decode_stream.options for the
+      same reason as fuzz_encode_stream. The alone decoder fuzz target still
+      has this restriction.
+    
+    - Altered the dictionary contents for fuzz_lzma.dict. Instead of keeping
+      the properties static and varying the dictionary size, the properties
+      are varied and the dictionary size is kept small. The dictionary size
+      doesn't have much impact on the code paths but the properties do.
+    
+    Closes: https://github.com/tukaani-project/xz/pull/73

-    Tests: test_files.sh: Make it not fail if features were disabled at build.
+    Tests: Add fuzz_encode_stream ossfuzz target.
     
-    It now tries to test as many files as easily possible.
-    The exit status indicates skipping if any of the files were
-    skipped. This way it is easy to notice if something is being
-    skipped when it isn't expected.
+    This fuzz target handles .xz stream encoding. The first byte of input
+    is used to dynamically set the preset level in order to increase the
+    fuzz coverage of complex critical code paths.

-    Tests: test_files.sh: Suppress an expected warning from the log.
+    Tests: Add fuzz_decode_alone OSS-Fuzz target
     
-    xz (but not xzdec) will normally warn about unsupported check
-    but since we are testing specifically such a file, it's better
-    to silence that warning so that it doesn't look suspicious in
-    test_files.sh.log.
+    This fuzz target that handles LZMA alone decoding. A new fuzz
+    dictionary .dict was also created with common LZMA header values to
+    help speed up the discovery of valid headers.

+
+    Tests: Update OSS-Fuzz Makefile.
     
-    The use of -q and -Q in xzdec is just for consistency and
-    doesn't affect the result at least for now.
+    All .c files can be built as separate fuzz targets. This simplifies
+    the Makefile by allowing us to use wildcards instead of having a
+    Makefile target for each fuzz target.

-    xz: Fix decompressor behavior if input uses an unsupported check type.
-    
-    Now files with unsupported check will make xz display
-    a warning, set the exit status to 2 (unless --no-warn is used),
-    and then decompress the file normally. This is how it was
-    supposed to work since the beginning but this was broken by
-    the commit 231c3c7098f1099a56abb8afece76fc9b8699f05, that is,
-    a little before 5.0.0 was released. The buggy behavior displayed
-    a message, set exit status 1 (error), and xz didn't attempt to
-    to decompress the file.
+    CMake: Change __attribute__((__ifunc__())) detection.
     
-    This doesn't matter today except for special builds that disable
-    CRC64 or SHA-256 at build time (but such builds should be used
-    in special situations only). The bug matters if new check type
-    is added in the future and an old xz version is used to decompress
-    such a file; however, it's likely that such files would use a new
-    filter too and an old xz wouldn't be able to decompress the file
-    anyway.
+    This renames ALLOW_ATTR_IFUNC to USE_ATTR_IFUNC and applies the ifunc
+    detection changes that were made to the Autotools build.
     
-    The first hunk in the commit is the actual fix. The second hunk
-    is a cleanup since LZMA_TELL_ANY_CHECK isn't used in xz.
-    
-    There is a test file for unsupported check type but it wasn't
-    used by test_files.sh, perhaps due to different behavior between
-    xz and the simpler xzdec.
+    Fixes: https://github.com/tukaani-project/xz/issues/70

-    xz: Refactor to remove is_empty_filename().
+    Build: Change --enable-ifunc handling.
+    
+    Some compilers support __attribute__((__ifunc__())) even though the
+    dynamic linker does not. The compiler is able to create the binary
+    but it will fail on startup. So it is not enough to just test if
+    the attribute is supported.
     
-    Long ago it was used in list.c too but nowadays it's needed
-    only in io_open_src() so it's nicer to avoid a separate function.
+    The default value for enable_ifunc is now auto, which will attempt
+    to compile a program using __attribute__((__ifunc__())). There are
+    additional checks in this program if glibc is being used or if it
+    is running on FreeBSD.
+    
+    Setting --enable-ifunc will skip this test and always enable
+    __attribute__((__ifunc__())), even if is not supported.

-    xz: If input file cannot be removed, treat it as a warning, not error.
-    
-    Treating it as a warning (message + exit status 2) matches gzip
-    and it seems more logical as at that point the output file has
-    already been successfully closed. When it's a warning it is
-    possible to suppress it with --no-warn.

-    tuklib_cpucores: Use HW_NCPUONLINE on OpenBSD.
+    xz: Create separate is_tty() function.
     
-    On OpenBSD the number of cores online is often less
-    than what HW_NCPU would return because OpenBSD disables
-    simultaneous multi-threading (SMT) by default.
+    The new is_tty() will report if a file descriptor is a terminal or not.
+    On POSIX systems, it is a wrapper around isatty(). However, the native
+    Windows implementation of isatty() will return true for all character
+    devices, not just terminals. So is_tty() has a special case for Windows
+    so it can use alternative Windows API functions to determine if a file
+    descriptor is a terminal.

-    Tests: Skip tests in test_*.sh if encoders and/or decoders are disabled.
-    
-    This isn't perfect as the scripts can still fail if only
-    certain filters are disabled. This is still an improvement
-    as now "make check" has better behavior when all encoders
-    or decoders are disabled.
+    This fixes a bug with MSVC and MinGW-w64 builds that refused to read from
+    or write to non-terminal character devices because xz thought it was a
+    terminal. For instance:
     
-    Grepping ../config.h is simple and fairly clean but it only
-    works if config.h was created. CMake builds don't create
-    config.h but they don't use these test scripts either.
+        xz foo -c > /dev/null
     
-    Thanks to Sebastian Andrzej Siewior for reporting the problem.
-    Thanks to Jia Tan for the original patch which grepped xz
-    error messages instead of config.h.

-    liblzma: Fix copying of check type statistics in lzma_index_cat().
+    liblzma: Fix compilation of fastpos_tablegen.c.
     
-    The check type of the last Stream in dest was never copied to
-    dest->checks (the code tried to copy it but it was done too late).
-    This meant that the value returned by lzma_index_checks() would
-    only include the check type of the last Stream when multiple
-    lzma_indexes had been concatenated.
+    The macro lzma_attr_visibility_hidden has to be defined to make
+    fastpos.h usable. The visibility attribute is irrelevant to
+    fastpos_tablegen.c so simply #define the macro to an empty value.
     
-    In xz --list this meant that the summary would only list the
-    check type of the last Stream, so in this sense this was only
-    a visual bug. However, it's possible that some applications
-    use this information for purposes other than merely showing
-    it to the users in an informational message. I'm not aware of
-    such applications though and it's quite possible that such
-    applications don't exist.
+    fastpos_tablegen.c is never built by the included build systems
+    and so the problem wasn't noticed earlier. It's just a standalone
+    program for generating fastpos_table.c.
     
-    Regular streamed decompression in xz or any other application
-    doesn't use lzma_index_cat() and so this bug cannot affect them.
+    Fixes: https://github.com/tukaani-project/xz/pull/69
+    Thanks to GitHub user Jamaika1.

-    liblzma: Stream decoder: Fix restarting after LZMA_MEMLIMIT_ERROR.
-    
-    If lzma_code() returns LZMA_MEMLIMIT_ERROR it is now possible
-    to use lzma_memlimit_set() to increase the limit and continue
-    decoding. This was supposed to work from the beginning but
-    there was a bug. With other decoders (.lzma or threaded .xz)
-    this already worked correctly.
+    liblzma: Use lzma_always_inline in memcmplen.h.

-    liblzma: ARM64: Fix wrong comment in API doc.
+    liblzma: #define lzma_attr_visibility_hidden in common.h.
+    
+    In ELF shared libs:
+    
+    -fvisibility=hidden affects definitions of symbols but not
+    declarations.[*] This doesn't affect direct calls to functions
+    inside liblzma as a linker can replace a call to lzma_foo@plt
+    with a call directly to lzma_foo when -fvisibility=hidden is used.
+    
+    [*] It has to be like this because otherwise every installed
+        header file would need to explictly set the symbol visibility
+        to default.
+    
+    When accessing extern variables that aren't defined in the
+    same translation unit, compiler assumes that the variable has
+    the default visibility and thus indirection is needed. Unlike
+    function calls, linker cannot optimize this.
+    
+    Using __attribute__((__visibility__("hidden"))) with the extern
+    variable declarations tells the compiler that indirection isn't
+    needed because the definition is in the same shared library.
     
-    Thanks to Jia Tan.
+    About 15+ years ago, someone told me that it would be good if
+    the CRC tables would be defined in the same translation unit
+    as the C code of the CRC functions. While I understood that it
+    could help a tiny amount, I didn't want to change the code because
+    a separate translation unit for the CRC tables was needed for the
+    x86 assembly code anyway. But when visibility attributes are
+    supported, simply marking the extern declaration with the
+    hidden attribute will get identical result. When there are only
+    a few affected variables, this is trivial to do. I wish I had
+    understood this back then already.

-    xz: Add --experimental-arm64[=width=WIDTH].
-    
-    It will be renamed to --arm64 once it is stable.
+    liblzma: Refer to MinGW-w64 instead of MinGW in the API headers.
     
-    Man page or --long-help weren't updated yet.
+    MinGW (formely a MinGW.org Project, later the MinGW.OSDN Project
+    at <https://osdn.net/projects/mingw/>) has GCC 9.2.0 as the
+    most recent GCC package (released 2021-02-02). The project might
+    still be alive but majority of people have switched to MinGW-w64.
+    Thus it seems clearer to refer to MinGW-w64 in our API headers too.
+    Building with MinGW is likely to still work but I haven't tested it
+    in the recent years.

-    liblzma: Add experimental ARM64 BCJ filter with a temporary Filter ID.
+    CMake: Use -D_FILE_OFFSET_BITS=64 if (and only if) needed.
+    
+    A CMake option LARGE_FILE_SUPPORT is created if and only if
+    -D_FILE_OFFSET_BITS=64 affects sizeof(off_t).
     
-    That is, the Filter ID will be changed once the design is final.
-    The current version will be removed. So files created with the
-    tempoary Filter ID won't be supported in the future.
+    This is needed on many 32-bit platforms and even with 64-bit builds
+    with MinGW-w64 to get support for files larger than 2 GiB.

-    liblzma: Simple/BCJ filters: Allow disabling generic BCJ options.
+    CMake: Generate and install liblzma.pc if not using MSVC.
     
-    This will be needed for the ARM64 BCJ filter as it will use
-    its own options struct.
+    Autotools based build uses -pthread and thus adds it to Libs.private
+    in liblzma.pc. CMake doesn't use -pthread at all if pthread functions
+    are available in libc so Libs.private doesn't get -pthread either.

-    Tests: Add a test file for lzma_index_append() integer overflow bug.
+    CMake: Rearrange the PACKAGE_ variables.
     
-    This test fails before commit 18d7facd3802b55c287581405c4d49c98708c136.
+    The windres workaround now replaces spaces with \x20 so
+    the package name isn't repeated.
     
-    test_files.sh now runs xz -l for bad-3-index-uncomp-overflow.xz
-    because only then the previously-buggy code path gets tested.
-    Normal decompression doesn't use lzma_index_append() at all.
-    Instead, lzma_index_hash functions are used and those already
-    did the overflow check.
+    These changes will help with creation of liblzma.pc.

-    bd7b290f3fe4faeceb7d3497ed9bf2e6ed5e7dc5 (2022-07-18), and

-    5.2.6 is the only stable release that included
-    this problem.

-    Thanks to Kevin R. Bulgrien for reporting the problem

-    liblzma: lzma_filters_copy: Keep dest[] unmodified if an error occurs.
+    Build: Detect -fsanitize= in CFLAGS and incompatible build options.
     
-    lzma_stream_encoder() and lzma_stream_encoder_mt() always assumed
-    this. Before this patch, failing lzma_filters_copy() could result
-    in free(invalid_pointer) or invalid memory reads in stream_encoder.c
-    or stream_encoder_mt.c.
+    Now configure will fail if -fsanitize= is found in CFLAGS
+    and sanitizer-incompatible ifunc or Landlock sandboxing
+    would be used. These are incompatible with one or more sanitizers.
+    It's simpler to reject all -fsanitize= uses instead of trying to
+    pass those that might not cause problems.
     
-    To trigger this, allocating memory for a filter options structure
-    has to fail. These are tiny allocations so in practice they very
-    rarely fail.
-    
-    Certain badness in the filter chain array could also make
-    lzma_filters_copy() fail but both stream_encoder.c and
-    stream_encoder_mt.c validate the filter chain before
-    trying to copy it, so the crash cannot occur this way.
+    CMake-based build was updated similarly. It lets the configuration
+    finish (SEND_ERROR instead of FATAL_ERROR) so that both error
+    messages can be seen at once.

-    liblzma: lzma_index_append: Add missing integer overflow check.
+    CI: Disable sandboxing in fsanitize=address,undefined job.
     
-    The documentation in src/liblzma/api/lzma/index.h suggests that
-    both the unpadded (compressed) size and the uncompressed size
-    are checked for overflow, but only the unpadded size was checked.
-    The uncompressed check is done first since that is more likely to
-    occur than the unpadded or index field size overflows.

+    The sandboxing on Linux now supports Landlock, which restricts all
+    supported filesystem actions after xz opens the files it needs. The
+    sandbox is only enabled when one file is input and we are writing to
+    standard out. With fsanitize=address,undefined, the instrumentation
+    needs to read additional files after the sandbox is in place. This
+    forces all xz based test to fail, so the sandbox must instead be
+    disabled.

-    CMake: Update for liblzma_*.map files and fix wrong common_w32res.rc dep.
-    
-    The previous commit split liblzma.map into liblzma_linux.map and
-    liblzma_generic.map. This commit updates the CMake build for those.
-    
-    common_w32res.rc dependency was listed under Linux/FreeBSD while
-    obviously it belongs to Windows when building a DLL.

-    liblzma: Vaccinate against an ill patch from RHEL/CentOS 7.
-    
-    RHEL/CentOS 7 shipped with 5.1.2alpha, including the threaded
-    encoder that is behind #ifdef LZMA_UNSTABLE in the API headers.
-    In 5.1.2alpha these symbols are under XZ_5.1.2alpha in liblzma.map.
-    API/ABI compatibility tracking isn't done between development
-    releases so newer releases didn't have XZ_5.1.2alpha anymore.
-    
-    Later RHEL/CentOS 7 updated xz to 5.2.2 but they wanted to keep
-    the exported symbols compatible with 5.1.2alpha. After checking
-    the ABI changes it turned out that >= 5.2.0 ABI is backward
-    compatible with the threaded encoder functions from 5.1.2alpha
-    (but not vice versa as fixes and extensions to these functions
-    were made between 5.1.2alpha and 5.2.0).
-    
-    In RHEL/CentOS 7, XZ Utils 5.2.2 was patched with
-    xz-5.2.2-compat-libs.patch to modify liblzma.map:
-    
-      - XZ_5.1.2alpha was added with lzma_stream_encoder_mt and
-        lzma_stream_encoder_mt_memusage. This matched XZ Utils 5.1.2alpha.
-    
-      - XZ_5.2 was replaced with XZ_5.2.2. It is clear that this was
-        an error; the intention was to keep using XZ_5.2 (XZ_5.2.2
-        has never been used in XZ Utils). So XZ_5.2.2 lists all
-        symbols that were listed under XZ_5.2 before the patch.
-        lzma_stream_encoder_mt and _mt_memusage are included too so
-        they are listed both here and under XZ_5.1.2alpha.
-    
-    The patch didn't add any __asm__(".symver ...") lines to the .c
-    files. Thus the resulting liblzma.so exports the threaded encoder
-    functions under XZ_5.1.2alpha only. Listing the two functions
-    also under XZ_5.2.2 in liblzma.map has no effect without
-    matching .symver lines.
-    
-    The lack of XZ_5.2 in RHEL/CentOS 7 means that binaries linked
-    against unpatched XZ Utils 5.2.x won't run on RHEL/CentOS 7.
-    This is unfortunate but this alone isn't too bad as the problem
-    is contained within RHEL/CentOS 7 and doesn't affect users
-    of other distributions. It could also be fixed internally in
-    RHEL/CentOS 7.
-    
-    The second problem is more serious: In XZ Utils 5.2.2 the API
-    headers don't have #ifdef LZMA_UNSTABLE for obvious reasons.
-    This is true in RHEL/CentOS 7 version too. Thus now programs
-    using new APIs can be compiled without an extra #define. However,
-    the programs end up depending on symbol version XZ_5.1.2alpha
-    (and possibly also XZ_5.2.2) instead of XZ_5.2 as they would
-    with an unpatched XZ Utils 5.2.2. This means that such binaries
-    won't run on other distributions shipping XZ Utils >= 5.2.0 as
-    they don't provide XZ_5.1.2alpha or XZ_5.2.2; they only provide
-    XZ_5.2 (and XZ_5.0). (This includes RHEL/CentOS 8 as the patch
-    luckily isn't included there anymore with XZ Utils 5.2.4.)
-    
-    Binaries built by RHEL/CentOS 7 users get distributed and then
-    people wonder why they don't run on some other distribution.
-    Seems that people have found out about the patch and been copying
-    it to some build scripts, seemingly curing the symptoms but
-    actually spreading the illness further and outside RHEL/CentOS 7.
-    
-    The ill patch seems to be from late 2016 (RHEL 7.3) and in 2017 it
-    had spread at least to EasyBuild. I heard about the events only
-    recently. :-(
-    
-    This commit splits liblzma.map into two versions: one for
-    GNU/Linux and another for other OSes that can use symbol versioning
-    (FreeBSD, Solaris, maybe others). The Linux-specific file and the
-    matching additions to .c files add full compatibility with binaries
-    that have been built against a RHEL/CentOS-patched liblzma. Builds
-    for OSes other than GNU/Linux won't get the vaccine as they should
-    be immune to the problem (I really hope that no build script uses
-    the RHEL/CentOS 7 patch outside GNU/Linux).
-    
-    The RHEL/CentOS compatibility symbols XZ_5.1.2alpha and XZ_5.2.2
-    are intentionally put *after* XZ_5.2 in liblzma_linux.map. This way
-    if one forgets to #define HAVE_SYMBOL_VERSIONS_LINUX when building,
-    the resulting liblzma.so.5 will have lzma_stream_encoder_mt@@XZ_5.2
-    since XZ_5.2 {...} is the first one that lists that function.
-    Without HAVE_SYMBOL_VERSIONS_LINUX @XZ_5.1.2alpha and @XZ_5.2.2
-    will be missing but that's still a minor problem compared to
-    only having lzma_stream_encoder_mt@@XZ_5.1.2alpha!
-    
-    The "local: *;" line was moved to XZ_5.0 so that it doesn't need
-    to be moved around. It doesn't matter where it is put.
-    
-    Having two similar liblzma_*.map files is a bit silly as it is,
-    at least for now, easily possible to generate the generic one
-    from the Linux-specific file. But that adds extra steps and
-    increases the risk of mistakes when supporting more than one
-    build system. So I rather maintain two files in parallel and let
-    validate_map.sh check that they are in sync when "make mydist"
-    is run.
-    
-    This adds .symver lines for lzma_stream_encoder_mt@XZ_5.2.2 and
-    lzma_stream_encoder_mt_memusage@XZ_5.2.2 even though these
-    weren't exported by RHEL/CentOS 7 (only @@XZ_5.1.2alpha was
-    for these two). I added these anyway because someone might
-    misunderstand the RHEL/CentOS 7 patch and think that @XZ_5.2.2
-    (@@XZ_5.2.2) versions were exported too.
-    
-    At glance one could suggest using __typeof__ to copy the function
-    prototypes when making aliases. However, this doesn't work trivially
-    because __typeof__ won't copy attributes (lzma_nothrow, lzma_pure)
-    and it won't change symbol visibility from hidden to default (done
-    by LZMA_API()). Attributes could be copied with __copy__ attribute
-    but that needs GCC 9 and a fallback method would be needed anyway.
-    
-    This uses __symver__ attribute with GCC >= 10 and
-    __asm__(".symver ...") with everything else. The attribute method
-    is required for LTO (-flto) support with GCC. Using -flto with
-    GCC older than 10 is now broken on GNU/Linux and will not be fixed
-    (can silently result in a broken liblzma build that has dangerously
-    incorrect symbol versions). LTO builds with Clang seem to work
-    with the traditional __asm__(".symver ...") method.
-    
-    Thanks to Boud Roukema for reporting the problem and discussing
-    the details and testing the fix.

+

-    Thanks to Cristian Othón Martínez Vera and Jia Tan.

-    Translations: Add Korean translation.
+    xz/Windows: Ensure that clock_gettime() isn't used with MinGW-w64.
+    
+    This commit alone doesn't change anything in the real-world:
+    
+      - configure.ac currently checks for clock_gettime() only
+        when using pthreads.
+    
+      - CMakeLists.txt doesn't check for clock_gettime() on Windows.
+    
+    So clock_gettime() wasn't used with MinGW-w64 before either.
+    
+    clock_gettime() provides monotonic time and it's better than
+    gettimeofday() in this sense. But clock_gettime() is defined
+    in winpthreads, and liblzma or xz needs nothing else from
+    winpthreads. By avoiding clock_gettime(), we avoid the dependency on
+    libwinpthread-1.dll or the need to link against the static version.
     
-    Thanks to Seong-ho Cho and Jia Tan.
+    As a bonus, GetTickCount64() and MinGW-w64's gettimeofday() can be
+    faster than clock_gettime(CLOCK_MONOTONIC, &tv). The resolution
+    is more than good enough for the progress indicator in xz.

-    Translations: Add partial Danish translation.
+    liblzma: Move is_clmul_supported() back to crc_common.h.
     
-    I made a few minor white space changes without getting them
-    approved by the Danish translation team.
+    This partially reverts creating crc_clmul.c
+    (8c0f9376f58c0696d5d6719705164d35542dd891) where is_clmul_supported()
+    was moved, extern'ed, and renamed to lzma_is_clmul_supported(). This
+    caused a problem when the function call to lzma_is_clmul_supported()
+    results in a call through the PLT. ifunc resolvers run very early in
+    the dynamic loading sequence, so the PLT may not be setup properly at
+    this point. Whether the PLT is used or not for
+    lzma_is_clmul_supported() depened upon the compiler-toolchain used and
+    flags.
+    
+    In liblzma compiled with GCC, for instance, GCC will go through the PLT
+    for function calls internal to liblzma if the version scripts and
+    symbol visibility hiding are not used. If lazy-binding is disabled,
+    then it would have made any program linked with liblzma fail during
+    dynamic loading in the ifunc resolver.

-    Translations: Add hu, zh_CN, and zh_TW.

-    I made a few white space changes to these without getting them

-    zh_TW teams but didn't succeed. I didn't contact the zh_CN team.)
+    Currently crc32 is always enabled, so COND_CHECK_CRC32 must always be

-    Translations: Add fi and pt_BR, and update de, fr, it, and pl.
+    liblzma: Fix -fsanitize=address failure with crc_clmul functions.
+    
+    After forcing crc_simd_body() to always be inlined it caused
+    -fsanitize=address to fail for lzma_crc32_clmul() and
+    lzma_crc64_clmul(). The __no_sanitize_address__ attribute was added
+    to lzma_crc32_clmul() and lzma_crc64_clmul(), but not removed from
+    crc_simd_body(). ASAN and inline functions behavior has changed over
+    the years for GCC specifically, so while strictly required we will
+    keep __attribute__((__no_sanitize_address__)) on crc_simd_body() in
+    case this becomes a requirement in the future.
     
-    The German translation isn't identical to the file in
-    the Translation Project but the changes (white space changes
-    only) were approved by the translator Mario Blättermann.
+    Older GCC versions refuse to inline a function with ASAN if the
+    caller and callee do not agree on sanitization flags
+    (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89124#c3). If the
+    function was forced to be inlined, it will not compile if the callee
+    function has __no_sanitize_address__ but the caller doesn't.

-    --robot mode wasn't changed yet.
+    Documentation about an autodetection bug when using ARM64 GCC
+    with -mstrict-align was added to INSTALL.

+    liblzma: Set the MSVC optimization fix to only cover lzma_crc64_clmul().
     
-    That commit fixed liblzma.dll build with CMake while keeping it
-    working with Autotools on Windows but the VS project files were
-    forgotten.
-    
-    I haven't tested these changes.
-    
-    Thanks to Olivier B. for reporting the bug and for the initial patch.
+    After testing a 32-bit Release build on MSVC, only lzma_crc64_clmul()
+    has the bug. crc_simd_body() and lzma_crc32_clmul() do not need the
+    optimizations disabled.

-    Build: Start the generated ChangeLog from around 5.2.0 instead of 5.0.0.
+    liblzma: Add the crc_always_inline macro to crc_simd_body().
     
-    This makes ChangeLog smaller.
+    Forcing this to be inline has a significant speed improvement at the
+    cost of a few repeated instructions. The compilers tested on did not
+    inline this function since it is large and is used twice in the same
+    translation unit.

-    Translations: Change the copyright comment string to use with po4a.
+    liblzma: Create crc_always_inline macro.
+    
+    This macro must be used instead of the inline keyword. On MSVC, it is
+    a replacement for __forceinline which is an MSVC specific keyword that
+    should not be used with inline (it will issue a warning if it is).
     
-    This affects the second line in po4a/xz-man.pot. The man pages of
-    xzdiff, xzgrep, and xzmore are from GNU gzip and under GNU GPLv2+
-    while the rest of the man pages are in the public domain.
+    It does not use a build system check to determine if
+    __attribute__((__always_inline__)) since all compilers that can use
+    CLMUL extensions (except the special case for MSVC) should support this
+    attribute. If this assumption is incorrect then it will result in a bug
+    report instead of silently producing slow code.

-    liblzma: Refactor lzma_mf_is_supported() to use a switch-statement.
+    liblzma: Refactor CRC comments.
+    
+    A detailed description of the three dispatch methods was added. Also,
+    duplicated comments now only appear in crc32_fast.c or were removed from
+    both crc32_fast.c and crc64_fast.c if they appeared in crc_clmul.c.

-    Build: Don't allow empty LIST in --enable-match-finders=LIST.
+    liblzma: Create crc_clmul.c.
     
-    It's enforced only when a match finder is needed, that is,
-    when LZMA1 or LZMA2 encoder is enabled.
+    Both crc32_clmul() and crc64_clmul() are now exported from
+    crc32_clmul.c as lzma_crc32_clmul() and lzma_crc64_clmul(). This
+    ensures that is_clmul_supported() (now lzma_is_clmul_supported()) is
+    not duplicated between crc32_fast.c and crc64_fast.c.
+    
+    Also, it encapsulates the complexity of the CLMUL implementations into a
+    single file and reduces the complexity of crc32_fast.c and crc64_fast.c.
+    Before, CLMUL code was present in crc32_fast.c, crc64_fast.c, and
+    crc_common.h.
+    
+    During the conversion, various cleanups were applied to code (thanks to
+    Lasse Collin) including:
+    
+    - Require using semicolons with MASK_/L/H/LH macros.
+    - Variable typing and const handling improvements.
+    - Improvements to comments.
+    - Fixes to the pragmas used.
+    - Removed unneeded variables.
+    - Whitespace improvements.
+    - Fixed CRC_USE_GENERIC_FOR_SMALL_INPUTS handling.
+    - Silenced warnings and removed the need for some #pragmas

-    xzgrep: Improve error handling, especially signals.
+    CI: Bump and ref actions by commit SHA in windows-ci.yml
     
-    xzgrep wouldn't exit on SIGPIPE or SIGQUIT when it clearly
-    should have. It's quite possible that it's not perfect still
-    but at least it's much better.
+    Referencing actions by commit SHA in GitHub workflows guarantees you are using an immutable version. Actions referenced by tags and branches are more vulnerable to attacks, such as the tag being moved to a malicious commit or a malicious commit being pushed to the branch.
     
-    If multiple exit statuses compete, now it tries to pick
-    the largest of value.
+    It's important to make sure the SHA's are from the original repositories and not forks.
     
-    Some comments were added.
+    For reference:
     
-    The exit status handling of signals is still broken if the shell
-    uses values larger than 255 in $? to indicate that a process
-    died due to a signal ***and*** their "exit" command doesn't take
-    this into account. This seems to work well with the ksh and yash
-    versions I tried. However, there is a report in gzip/zgrep that
-    OpenSolaris 5.11 (not 5.10) has a problem with "exit" truncating
-    the argument to 8 bits:
+    https://github.com/msys2/setup-msys2/releases/tag/v2.20.1
+    https://github.com/msys2/setup-msys2/commit/27b3aa77f672cb6b3054121cfd80c3d22ceebb1d

+    https://github.com/actions/checkout/commit/8ade135a41bc03ea155e62e844d188df1ea18608
     
-    Such a bug would break xzgrep but I didn't add a workaround
-    at least for now. 5.11 is old and I don't know if the problem
-    exists in modern descendants, or if the problem exists in other
-    ksh implementations in use.

-    xzgrep: Use grep -H --label when available (GNU, *BSDs).
+    CI: Bump and ref actions by commit SHA in ci.yml
+    
+    Referencing actions by commit SHA in GitHub workflows guarantees you are using an immutable version. Actions referenced by tags and branches are more vulnerable to attacks, such as the tag being moved to a malicious commit or a malicious commit being pushed to the branch.
+    
+    It's important to make sure the SHA's are from the original repositories and not forks.
     
-    It avoids the use of sed for prefixing filenames to output lines.
-    Using sed for that is slower and prone to security bugs so now
-    the sed method is only used as a fallback.
+    For reference:
     
-    This also fixes an actual bug: When grepping a binary file,
-    GNU grep nowadays prints its diagnostics to stderr instead of
-    stdout and thus the sed-method for prefixing the filename doesn't
-    work. So with this commit grepping binary files gives reasonable
-    output with GNU grep now.

-    xzgrep: Add more LC_ALL=C to avoid bugs with multibyte characters.
-    
-    Also replace one use of expr with printf.
-    
-    The rationale for LC_ALL=C was already mentioned in
-    69d1b3fc29677af8ade8dc15dba83f0589cb63d6 that fixed a security
-    issue. However, unrelated uses weren't changed in that commit yet.
+    CMake/Windows: Fix when the windres workaround is applied.
     
-    POSIX says that with sed and such tools one should use LC_ALL=C
-    to ensure predictable behavior when strings contain byte sequences
-    that aren't valid multibyte characters in the current locale. See
-    under "Application usage" in here:
+    CMake doesn't set WIN32 on CYGWIN but the workaround is
+    probably needed on Cygwin too. Same for MSYS and MSYS2.
     
-    https://pubs.opengroup.org/onlinepubs/9699919799/utilities/sed.html
+    The workaround must not be used with Clang that is acting in
+    MSVC mode. This fixes it by checking for the known environments
+    that need the workaround instead of using "NOT MSVC".
     
-    With GNU sed invalid multibyte strings would work without this;
-    it's documented in its Texinfo manual. Some other implementations
-    aren't so forgiving.
+    Thanks to Martin Storsjö.

-    xzgrep: Fix parsing of certain options.
+    CI: Disable CLANG64 MSYS2 environment until bug is resolved.
     
-    Fix handling of "xzgrep -25 foo" (in GNU grep "grep -25 foo" is
-    an alias for "grep -C25 foo"). xzgrep would treat "foo" as filename
-    instead of as a pattern. This bug was fixed in zgrep in gzip in 2012.
+    lld 17.0.1 searches for libraries to link first in the toolchain
+    directories before the local directory when building. The is a problem
+    for us because liblzma.a is installed in MSYS2 CLANG64 by default and
+    xz.exe will thus use the installed library instead of the one being
+    built.
     
-    Add -E, -F, -G, and -P to the "no argument required" list.
+    This causes tests to fail when they are expecting features to be
+    disabled. More importantly, it will compile xz.exe with an incorrect
+    liblzma and could cause unexpected behavior by being unable to update
+    liblzma code in static builds. The CLANG64 environment can be tested
+    again once this is fixed.
     
-    Add -X to "argument required" list. It is an
-    intentionally-undocumented GNU grep option so this isn't
-    an important option for xzgrep but it seems that other grep
-    implementations (well, those that I checked) don't support -X
-    so I hope this change is an improvement still.
+    Link to bug: https://github.com/llvm/llvm-project/issues/67779.

+
+    CMake: Rename xz and man page symlink custom targets.
     
-    grep -d (grep --directories=ACTION) requires an argument. In
-    contrast to zgrep, I kept -d in the "no argument required" list
-    because it's not supported in xzgrep (or zgrep). This way
-    "xzgrep -d" gives an error about option being unsupported instead
-    of telling that it requires an argument. Both zgrep and xzgrep

-    liblzma: Add optional autodetection of LZMA end marker.
+    Build: Fix __attribute__((ifunc(...))) detection with clang -Wall.
     
-    Turns out that this is needed for .lzma files as the spec in
-    LZMA SDK says that end marker may be present even if the size
-    is stored in the header. Such files are rare but exist in the
-    real world. The code in liblzma is so old that the spec didn't
-    exist in LZMA SDK back then and I had understood that such
-    files weren't possible (the lzma tool in LZMA SDK didn't
-    create such files).
+    Now if user-supplied CFLAGS contains -Wall -Wextra -Wpedantic
+    the two checks that need -Werror will still work.
     
-    This modifies the internal API so that LZMA decoder can be told
-    if EOPM is allowed even when the uncompressed size is known.
-    It's allowed with .lzma and not with other uses.
+    At CMake side there is add_compile_options(-Wall -Wextra)
+    but it didn't affect the -Werror tests. So with both Autotools
+    and CMake only user-supplied CFLAGS could make the checks fail
+    when they shouldn't.
     
-    Thanks to Karl Beldan for reporting the problem.
+    This is not a full fix as things like -Wunused-macros in
+    user-supplied CFLAGS will still cause problems with both
+    GCC and Clang.

-    Created script to generate code coverage reports.
+    Build: Silence two Autoconf warnings.
+    
+    There were two uses of AC_COMPILE_IFELSE that didn't use
+    AC_LANG_SOURCE and Autoconf warned about these. The omission
+    had been intentional but it turned out that this didn't do
+    what I thought it would.
+    
+    Autoconf 2.71 manual gives an impression that AC_LANG_SOURCE
+    inserts all #defines that have been made with AC_DEFINE so
+    far (confdefs.h). The idea was that omitting AC_LANG_SOURCE
+    would mean that only the exact code included in the
+    AC_COMPILE_IFELSE call would be compiled.
+    
+    With C programs this is not true: the #defines get added without
+    AC_LANG_SOURCE too. There seems to be no neat way to avoid this.
+    Thus, with the C language at least, adding AC_LANG_SOURCE makes
+    no other difference than silencing a warning from Autoconf. The
+    generated "configure" remains identical. (Docs of AC_LANG_CONFTEST
+    say that the #defines have been inserted since Autoconf 2.63b and
+    that AC_COMPILE_IFELSE uses AC_LANG_CONFTEST. So the behavior is
+    documented if one also reads the docs of macros that one isn't
+    calling directly.)
+    
+    Any extra code, including #defines, can cause problems for
+    these two tests because these tests must use -Werror.
+    CC=clang CFLAGS=-Weverything is the most extreme example.
+    It enables -Wreserved-macro-identifier which warns about
+    #define __EXTENSIONS__ 1 because it begins with two underscores.
+    It's possible to write a test file that passes -Weverything but
+    it becomes impossible when Autoconf inserts confdefs.h.
     
-    The script uses lcov and genhtml after running the tests
-    to show the code coverage statistics. The script will create
-    a coverage directory where it is run. It can be run both in
-    and out of the source directory.
+    So this commit adds AC_LANG_SOURCE to silence Autoconf warnings.
+    A different solution is needed for -Werror tests.

-    Tests: Add test file good-1-empty-bcj-lzma2.xz.
+    lib: Update getopt.in.h from Gnulib with modifications.
+    
+    We can still avoid modifying the contents of this file during
+    configuration to simplify the build systems. Gnulib added replacements
+    for inclusions guards for Cygwin. Cygwin should not need getopt_long
+    replacement so this feature can be omitted.
+    
+    <unistd.h> is conditionally included to avoid MSVC since it is not
+    available.
     
-    This is from test_bcj_exact_size.c.
-    It's good to have it as a standalone file.
+    The definition for _GL_ARG_NONNULL was also copied into this file from
+    Gnulib since this stage is usually done during gnulib-tool.

-    Tests: Convert test_check to tuktest.
+    lib: Update getopt.c from Gnulib with modifications.
     
-    Thanks to Jia Tan for help with all the tests.
+    The code maintains the prior modifications of conditionally including
+    config.h and disabling NLS support.
+    
+    _GL_UNUSED is repalced with the simple cast to void trick. _GL_UNUSED
+    is only used for these two parameters so its simpler than having to
+    define it.

-    Tests: Convert test_block_header to tuktest.
+    lib: Add getopt-cdefs.h for getopt_long update.
+    
+    This was modified slightly from Gnulib. In Gnulib, it expects the
+    @HAVE_SYS_CDEFS_H@ to be replaced. Instead, we can set HAVE_SYS_CDEFS_H
+    on systems that have it and avoid copying another file into the build
+    directory. Since we are not using gnulib-tool, copying extra files
+    requires extra build system updates (and special handling with CMake) so
+    we should avoid when possible.

-    Tests: Convert test_bcj_exact_size to tuktest.
+    lib: Copy new header files from Gnulib without modification.
     
-    The compress() and decompress() functions were merged because
-    the later depends on the former so they need to be a single
-    test case.
+    The getopt related files have changed from Gnulib by splitting up
+    getopt.in.h into more modular header files. We could have kept
+    everything in just getopt.in.h, but this will help us continue to update
+    in the future.

-    Build: Enable Automake's parallel test harness.
-    
-    It has been the default for quite some time already and
-    the old serial harness isn't discouraged. The downside is
-    that with parallel tests one cannot print progress info or
-    other diagnostics to the terminal; all output from the tests
-    will be in the log files only. But now that the compression
-    tests are separated the parallel tests will speed things up.
+    sysdefs.h: Update the comment about __USE_MINGW_ANSI_STDIO.

-    Tests: Split test_compress.sh into separate test unit for each file.
+    xz: Windows: Don't (de)compress to special files like "con" or "nul".
     
-    test_compress.sh now takes one command line argument:
-    a filename to be tested. If it begins with "compress_generated_"
-    the file will be created with create_compress_files.
+    Before this commit, the following writes "foo" to the
+    console and deletes the input file:
     
-    This will allow parallel execution of the slow tests.
+        echo foo | xz > con_xz
+        xz --suffix=_xz --decompress con_xz
+    
+    It cannot happen without --suffix because names like con.xz
+    are also special and so attempting to decompress con.xz
+    (or compress con to con.xz) will already fail when opening
+    the input file.
+    
+    Similar thing is possible when compressing. The following
+    writes to "nul" and the input file "n" is deleted.
+    
+        echo foo | xz > n
+        xz --suffix=ul n
+    
+    Now xz checks if the destination is a special file before
+    continuing. DOS/DJGPP version had a check for this but
+    Windows (and OS/2) didn't.

+    xzdec might build with VS2013 but it hasn't been tested.
+    It was never supported before and VS2013 is old anyway
+    so for simplicity only liblzma is supported with VS2013.

+    
+    VS2013 update 2 should still be able to build liblzma.

+    Thanks to Kelvin Lee and Jia Tan for testing.

-    The SIZE_MAX / 3 was 1365 MiB. 1400 MiB gives little more room

-    xz: Add a default soft memory usage limit for --threads=0.
+    CMake: Add support for replacement getopt_long (lib/getopt*).
     
-    This is a soft limit in sense that it only affects the number of
-    threads. It never makes xz fail and it never makes xz change
-    settings that would affect the compressed output.
-    
-    The idea is to make -T0 have more reasonable behavior when
-    the system has very many cores or when a memory-hungry
-    compression options are used. This also helps with 32-bit xz,
-    preventing it from running out of address space.
-    
-    The downside of this commit is that now the number of threads
-    might become too low compared to what the user expected. I
-    hope this to be an acceptable compromise as the old behavior
-    has been a source of well-argued complaints for a long time.
+    Thanks to Jia Tan for the initial work. I added the libgnu target
+    and made a few related minor edits.

-    xz: Make -T0 use multithreaded mode on single-core systems.
+    CMake: Bump maximum policy version to 3.27.
     
-    The main problem withi the old behavior is that the compressed
-    output is different on single-core systems vs. multicore systems.
-    This commit fixes it by making -T0 one thread in multithreaded mode
-    on single-core systems.
+    There are several new policies. CMP0149 may affect the Windows SDK
+    version that CMake will choose by default. The new behavior is more
+    predictable, always choosing the latest SDK version by default.
     
-    The downside of this is that it uses more memory. However, if
-    --memlimit-compress is used, xz can (thanks to the previous commit)
-    drop to the single-threaded mode still.
+    The other new policies shouldn't affect this package.

-    xz: Changes to --memlimit-compress and --no-adjust.
+    lib/getopt*.c: Include <config.h> only HAVE_CONFIG_H is defined.
     
-    In single-threaded mode, --memlimit-compress can make xz scale down
-    the LZMA2 dictionary size to meet the memory usage limit. This
-    obviously affects the compressed output. However, if xz was in
-    threaded mode, --memlimit-compress could make xz reduce the number
-    of threads but it wouldn't make xz switch from multithreaded mode
-    to single-threaded mode or scale down the LZMA2 dictionary size.
-    This seemed illogical and there was even a "FIXME?" about it.
+    The CMake-based build doesn't use config.h.
     
-    Now --memlimit-compress can make xz switch to single-threaded
-    mode if one thread in multithreaded mode uses too much memory.
-    If memory usage is still too high, then the LZMA2 dictionary
-    size can be scaled down too.
-    
-    The option --no-adjust was also changed so that it no longer
-    prevents xz from scaling down the number of threads as that
-    doesn't affect compressed output (only performance). After
-    this commit --no-adjust only prevents adjustments that affect
-    compressed output, that is, with --no-adjust xz won't switch
-    from multithreaded mode to single-threaded mode and won't
-    scale down the LZMA2 dictionary size.
-    
-    The man page wasn't updated yet.
+    Up-to-date getopt_long in Gnulib is LGPLv2 so at some
+    point it could be included in XZ Utils too but for now
+    this commit is enough to make CMake-based build possible.

-    xz: Add --memlimit-mt-decompress along with a default limit value.
-    
-    --memlimit-mt-decompress allows specifying the limit for
-    multithreaded decompression. This matches memlimit_threading in
-    liblzma. This limit can only affect the number of threads being
-    used; it will never prevent xz from decompressing a file. The
-    old --memlimit-decompress option is still used at the same time.
-    
-    If the value of --memlimit-decompress (the default value or
-    one specified by the user) is less than the value of
-    --memlimit-mt-decompress , then --memlimit-mt-decompress is
-    reduced to match --memlimit-decompress.
-    
-    Man page wasn't updated yet.
+    Doxygen: Add more C macro names to PREDEFINED.

-    liblzma: Add a new flag LZMA_FAIL_FAST for threaded decoder.
+    xz, xzdec, lzmainfo: Use tuklib_attr_noreturn.
     
-    In most cases if the input file is corrupt the application won't
-    care about the uncompressed content at all. With this new flag
-    the threaded decoder will return an error as soon as any thread
-    has detected an error; it won't wait to copy out the data before
-    the location of the error.
+    For compatibility with C23's [[noreturn]], tuklib_attr_noreturn
+    must be at the beginning of declaration (before "extern" or
+    "static", and even before any GNU C's __attribute__).
     
-    I don't plan to use this in xz to keep the behavior consistent
-    between single-threaded and multi-threaded modes.
+    This commit also moves all other function attributes to
+    the beginning of function declarations. "extern" is kept
+    at the beginning of a line so the attributes are listed on
+    separate lines before "extern" or "static".

-    liblzma: Threaded decoder: Always wait for output if LZMA_FINISH is used.
+    Remove incorrect uses of __attribute__((__malloc__)).
     
-    This makes the behavior consistent with the single-threaded
-    decoder when handling truncated .xz files.
+    xrealloc() is obviously incorrect, modern GCC docs even
+    mention realloc() as an example where this attribute
+    cannot be used.
     
-    Thanks to Jia Tan for finding this issue.
+    liblzma's lzma_alloc() and lzma_alloc_zero() would be
+    correct uses most of the time but custom allocators
+    may use a memory pool or otherwise hold the pointer
+    so aliasing issues could happen in theory.
+    
+    The xstrdup() case likely was correct but I removed it anyway.
+    Now there are no __malloc__ attributes left in the code.
+    The allocations aren't in hot paths so this should make
+    no practical difference.

-    liblzma: Threaded decoder: Support zpipe.c-style decoding loop.
+    tuklib: Update tuklib_attr_noreturn for C11/C17 and C23.
     
-    This makes it possible to call lzma_code() in a loop that only
-    reads new input when lzma_code() didn't fill the output buffer
-    completely. That isn't the calling style suggested by the
-    liblzma example program 02_decompress.c so perhaps the usefulness
-    of this feature is limited.
+    This makes no difference for GCC or Clang as they support
+    GNU C's __attribute__((__noreturn__)) but this helps with MSVC:
     
-    Also, it is possible to write such a loop so that it works
-    with the single-threaded decoder but not with the threaded
-    decoder even after this commit, or so that it works only if
-    lzma_mt.timeout = 0.
+      - VS 2019 version 16.7 and later support _Noreturn if the
+        options /std:c11 or /std:c17 are used. This gets handled
+        with the check for __STDC_VERSION__ >= 201112.
     
-    The zlib tutorial <https://zlib.net/zlib_how.html> is a well-known
-    example of a loop where more input is read only when output isn't
-    full. Porting this as is to liblzma would work with the
-    single-threaded decoder (if LZMA_CONCATENATED isn't used) but it
-    wouldn't work with threaded decoder even after this commit because
-    the loop assumes that no more output is possible when it cannot
-    read more input ("if (strm.avail_in == 0) break;"). This cannot
-    be fixed at liblzma side; the loop has to be modified at least
-    a little.
+      - When MSVC isn't in C11/C17 mode, __declspec(noreturn) is used.
     
-    I'm adding this in any case because the actual code is simple
-    and short and should have no harmful side-effects in other
-    situations.
+    C23 will deprecate _Noreturn (and <stdnoreturn.h>)
+    for [[noreturn]]. This commit anticipates that but
+    the final __STDC_VERSION__ value isn't known yet.

-    xzgrep: Fix escaping of malicious filenames (ZDI-CAN-16587).
-    
-    Malicious filenames can make xzgrep to write to arbitrary files
-    or (with a GNU sed extension) lead to arbitrary code execution.
-    
-    xzgrep from XZ Utils versions up to and including 5.2.5 are
-    affected. 5.3.1alpha and 5.3.2alpha are affected as well.
-    This patch works for all of them.
-    
-    This bug was inherited from gzip's zgrep. gzip 1.12 includes
-    a fix for zgrep.
-    
-    The issue with the old sed script is that with multiple newlines,
-    the N-command will read the second line of input, then the
-    s-commands will be skipped because it's not the end of the
-    file yet, then a new sed cycle starts and the pattern space
-    is printed and emptied. So only the last line or two get escaped.
-    
-    One way to fix this would be to read all lines into the pattern
-    space first. However, the included fix is even simpler: All lines
-    except the last line get a backslash appended at the end. To ensure
-    that shell command substitution doesn't eat a possible trailing
-    newline, a colon is appended to the filename before escaping.
-    The colon is later used to separate the filename from the grep
-    output so it is fine to add it here instead of a few lines later.
+    MSVC: xz: Make file_io.c and file_io.h compatible with MSVC.
     
-    The old code also wasn't POSIX compliant as it used \n in the
-    replacement section of the s-command. Using \<newline> is the
-    POSIX compatible method.
-    
-    LC_ALL=C was added to the two critical sed commands. POSIX sed
-    manual recommends it when using sed to manipulate pathnames
-    because in other locales invalid multibyte sequences might
-    cause issues with some sed implementations. In case of GNU sed,
-    these particular sed scripts wouldn't have such problems but some
-    other scripts could have, see:
-    
-        info '(sed)Locale Considerations'
-    
-    This vulnerability was discovered by:
-    cleemy desu wayo working with Trend Micro Zero Day Initiative
-    
-    Thanks to Jim Meyering and Paul Eggert discussing the different
-    ways to fix this and for coordinating the patch release schedule
-    with gzip.
+    Thanks to Kelvin Lee for the original patches
+    and testing the modifications I made.

-    liblzma: Fix a deadlock in threaded decoder.
-    
-    If a worker thread has consumed all input so far and it's
-    waiting on thr->cond and then the main thread enables
-    partial update for that thread, the code used to deadlock.
-    This commit allows one dummy decoding pass to occur in this
-    situation which then also does the partial update.
-    
-    As part of the fix, this moves thr->progress_* updates to
-    avoid the second thr->mutex locking.

-    
-    LZMA_TIMED_OUT is not an error and thus stopping threads on
-    LZMA_TIMED_OUT breaks the decoder badly.
+    CI: Enable CLMUL in address sanitization test.
     
-    Thanks to Jia Tan for finding the bug and for the patch.
+    The crc64_clmul() function should be ignored by the address sanitizer
+    now so these builds should still pass.

-    xz: Add initial support for threaded decompression.
-    
-    If threading support is enabled at build time, this will
-    use lzma_stream_decoder_mt() even for single-threaded mode.
-    With memlimit_threading=0 the behavior should be identical.
-    
-    This needs some work like adding --memlimit-threading=LIMIT.
-    
-    The original patch from Sebastian Andrzej Siewior included
-    a method to get currently available RAM on Linux. It might
-    be one way to go but as it is Linux-only, the available-RAM
-    approach needs work for portability or using a fallback method
-    on other OSes.
-    
-    The man page wasn't updated yet.
+    Update THANKS.

-    liblzma: Add threaded .xz decompressor.
-    
-    I realize that this is about a decade late.
+    liblzma: Mark crc64_clmul() with __attribute__((__no_sanitize_address__)).
     
-    Big thanks to Sebastian Andrzej Siewior for the original patch.
-    I made a bunch of smaller changes but after a while quite a few
-    things got rewritten. So any bugs in the commit were created by me.

-    liblzma: Add new output queue (lzma_outq) features.
-    
-    Add lzma_outq_clear_cache2() which may leave one buffer allocated
-    in the cache.
-    
-    Add lzma_outq_outbuf_memusage() to get the memory needed for
-    a single lzma_outbuf. This is now used internally in outqueue.c too.
-    
-    Track both the total amount of memory allocated and the amount of
-    memory that is in active use (not in cache).
-    
-    In lzma_outbuf, allow storing the current input position that
-    matches the current output position. This way the main thread
-    can notice when no more output is possible without first providing
-    more input.
+    CMake: Fix unconditionally defining HAVE_CLOCK_MONOTONIC.
     
-    Allow specifying return code for lzma_outq_read() in a finished
-    lzma_outbuf.
+    If HAVE_CLOCK_GETTIME was defined, then HAVE_CLOCK_MONOTONIC was always
+    added as a compile definition even if the check for it failed.

-    liblzma: Make Block decoder catch certain types of errors better.
+    liblzma: Add overflow check for Unpadded size in lzma_index_append().
     
-    Now it limits the input and output buffer sizes that are
-    passed to a raw decoder. This way there's no need to check
-    if the sizes can grow too big or overflow when updating
-    Compressed Size and Uncompressed Size counts. This also means
-    that a corrupt file cannot cause the raw decoder to process
-    useless extra input or output that would exceed the size info
-    in Block Header (and thus cause LZMA_DATA_ERROR anyway).
+    This was not a security bug since there was no path to overflow
+    UINT64_MAX in lzma_index_append() or when it calls index_file_size().
+    The bug was discovered by a failing assert() in vli_ceil4() when called
+    from index_file_size() when unpadded_sum (the sum of the compressed size
+    of current Stream and the unpadded_size parameter) exceeds LZMA_VLI_MAX.
     
-    More importantly, now the size information is verified more
-    carefully in case raw decoder returns LZMA_OK. This doesn't
-    really matter with the current single-threaded .xz decoder
-    as the errors would be detected slightly later anyway. But
-    this helps avoiding corner cases in the upcoming threaded
-    decompressor, and it might help other Block decoder uses
-    outside liblzma too.
+    Previously, the unpadded_size parameter was checked to be not greater
+    than UNPADDED_SIZE_MAX, but no check was done once compressed_base was
+    added.
     
-    The test files bad-1-lzma2-{9,10,11}.xz test these conditions.
-    With the single-threaded .xz decoder the only difference is
-    that LZMA_DATA_ERROR is detected in a difference place now.
+    This could not have caused an integer overflow in index_file_size() when
+    called by lzma_index_append(). The calculation for file_size breaks down
+    into the sum of:
+    
+    - Compressed base from all previous Streams
+    - 2 * LZMA_STREAM_HEADER_SIZE (size of the current Streams header and
+      footer)
+    - stream_padding (can be set by lzma_index_stream_padding())
+    - Compressed base from the current Stream
+    - Unpadded size (parameter to lzma_index_append())
+    
+    The sum of everything except for Unpadded size must be less than
+    LZMA_VLI_MAX. This is guarenteed by overflow checks in the functions
+    that can set these values including lzma_index_stream_padding(),
+    lzma_index_append(), and lzma_index_cat(). The maximum value for
+    Unpadded size is enforced by lzma_index_append() to be less than or
+    equal UNPADDED_SIZE_MAX. Thus, the sum cannot exceed UINT64_MAX since
+    LZMA_VLI_MAX is half of UINT64_MAX.
+    
+    Thanks to Joona Kannisto for reporting this.

+    Build: Conditionally allow win95 threads and --enable-small.
     
-    This matches xz-utils 5.2.5-2 in Debian.
+    When the compiler supports __attribute__((__constructor__))
+    mythread_once() is never used, even with --enable-small. A configuration
+    with win95 threads and --enable-small will compile and be thread safe so
+    it can be allowed.
     
-    The translation was done by "bubu", proofread by the debian-l10n-french
-    mailing list contributors, and submitted to me on the xz-devel mailing
-    list by Jean-Pierre Giraud. Thanks to everyone!
+    This isn't a very common configuration since MSVC does not support
+    __attribute__((__constructor__)), but MINGW32 and CLANG32 environments
+    for MSYS2 can use win95 threads and have
+    __attribute__((__constructor__)) support.

-    
-    `egrep` and `fgrep` have been deprecated in GNU grep since 2007, and in
-    current post 3.7 Git they have been made to emit obsolescence warnings:

+    groff defaults to SGR escapes. Using -P-c passes -c to grotty

-    xz: Change the coding style of the previous commit.
+    mythread.h: Disable signal functions in builds targeting Wasm + WASI.
     
-    It isn't any better now but it's consistent with
-    the rest of the code base.
+    signal.h in WASI SDK doesn't currently provide sigprocmask()
+    or sigset_t. liblzma doesn't need them so this change makes
+    liblzma and xzdec build against WASI SDK. xz doesn't build yet
+    and the tests don't either as tuktest needs setjmp() which
+    isn't (yet?) implemented in WASI SDK.
+    
+    Closes: https://github.com/tukaani-project/xz/pull/57
+    See also: https://github.com/tukaani-project/xz/pull/56
+    
+    (The original commit was edited a little by Lasse Collin.)

-    OpenBSD does not allow to change the group of a file if the user

-    fails if the new group is the same as the old one.  Do not call

-    
-    This fixes an issue with Perl Alien::Build module.

-    liblzma: Use _MSVC_LANG to detect when "noexcept" can be used with MSVC.
-    
-    By default, MSVC always sets __cplusplus to 199711L. The real
-    C++ standard version is available in _MSVC_LANG (or one could
-    use /Zc:__cplusplus to set __cplusplus correctly).
+    CMake: Conditionally allow the creation of broken symlinks.
     
-    Fixes <https://sourceforge.net/p/lzmautils/discussion/708858/thread/f6bc3b108a/>.
+    The CMake build will try to create broken symlinks on Unix and Unix-like
+    platforms. Cygwin and MSYS2 are Unix-like, but may not be able to create
+    broken symlinks. The value of the CYGWIN or MSYS environment variables
+    determine if broken symlinks are valid.
     
-    Thanks to Dan Weiss.
+    The default for MSYS2 does not allow for broken symlinks, so the CMake
+    build has been broken for MSYS2 since commit
+    80a1a8bb838842a2be343bd88ad1462c21c5e2c9.

-    It still exists primarily for EROFS but MicroLZMA is
-    a more generic name (that hopefully doesn't clash with
-    something that already exists).
+    All of the MSYS2 environments need make, and it does not come with the

-    This was forgotten from 194029ffaf74282a81f0c299c07f73caca3232ca.
+    The default for many of the MSYS2 environments is for CMake to create

-    Reduce maximum possible memory limit on MIPS32
-    
-    Due to architectural limitations, address space available to a single
-    userspace process on MIPS32 is limited to 2 GiB, not 4, even on systems
-    that have more physical RAM -- e.g. 64-bit systems with 32-bit
-    userspace, or systems that use XPA (an extension similar to x86's PAE).
+    liblzma: Prevent an empty translation unit in Windows builds.
     
-    So, for MIPS32, we have to impose stronger memory limits. I've chosen
-    2000MiB to give the process some headroom.
+    To workaround Automake lacking Windows resource compiler support, an
+    empty source file is compiled to overwrite the resource files for static
+    library builds. Translation units without an external declaration are
+    not allowed by the C standard and result in a warning when used with
+    -Wempty-translation-unit (Clang) or -pedantic (GCC).

-    CMake: Try to improve compatibility with the FindLibLZMA module.
-    
-    The naming conflict with FindLibLZMA module gets worse.
-    Not avoiding it in the first place was stupid.
-    
-    Normally find_package(LibLZMA) will use the module and
-    find_package(liblzma 5.2.5 REQUIRED CONFIG) will use the config
-    file even with a case insensitive file system. However, if
-    CMAKE_FIND_PACKAGE_PREFER_CONFIG is TRUE and the file system
-    is case insensitive, find_package(LibLZMA) will find our liblzma
-    config file instead of using FindLibLZMA module.
-    
-    One big problem with this is that FindLibLZMA uses
-    LibLZMA::LibLZMA and we use liblzma::liblzma as the target
-    name. With target names CMake happens to be case sensitive.
-    To workaround this, this commit adds
-    
-        add_library(LibLZMA::LibLZMA ALIAS liblzma::liblzma)
+    CI: Add Windows runner for Autotools builds with MSYS2.
     
-    to the config file. Then both spellings work.
+    Only a subset of the tests run by the Linux and MacOS Autotools builds
+    are run. The most interesting tests are the ones that disable threads,
+    encoders, and decoders.
     
-    To make the behavior consistent between case sensitive and
-    insensitive file systems, the config and related files are
-    renamed from liblzmaConfig.cmake to liblzma-config.cmake style.
-    With this style CMake looks for lowercase version of the package
-    name so find_package(LiBLzmA 5.2.5 REQUIRED CONFIG) will work
-    to find our config file.
+    The Windows runner will only be run manually since these tests will
+    likely take much longer than the Linux and MacOS runners. This runner
+    should be used before merging any large features and before releases.
     
-    There are other differences between our config file and
-    FindLibLZMA so it's still possible that things break for
-    reasons other than the spelling of the target name. Hopefully
-    those situations aren't too common.
+    Currently the clang64 environment fails to due to a warning and
+    -Werror is enabled for the CI tests. This is still an early version
+    since the CMake build can be done for MSVC and optionally each of the
+    MSYS2 environments. GitHub does not allow manually running the CI tests
+    unless the workflow is checked on the default branch so checking in a
+    minimum version is a good idea.
     
-    When the config file is available, it should always give as good or
-    better results as FindLibLZMA so this commit doesn't affect the
-    recommendation to use find_package(liblzma 5.2.5 REQUIRED CONFIG)
-    which explicitly avoids FindLibLZMA.
+    Thanks to Arthur S for the original proposing the original patch.
     
-    Thanks to Markus Rickert.

-    liblzma: Add EROFS LZMA encoder and decoder.
-    
-    Right now this is just a planned extra-compact format for use
-    in the EROFS file system in Linux. At this point it's possible
-    that the format will either change or be abandoned and removed
-    completely.
-    
-    The special thing about the encoder is that it uses the
-    output-size-limited encoding added in the previous commit.
-    EROFS uses fixed-sized blocks (e.g. 4 KiB) to hold compressed
-    data so the compressors must be able to create valid streams
-    that fill the given block size.

-    liblzma: Add rough support for output-size-limited encoding in LZMA1.
-    
-    With this it is possible to encode LZMA1 data without EOPM so that
-    the encoder will encode as much input as it can without exceeding
-    the specified output size limit. The resulting LZMA1 stream will
-    be a normal LZMA1 stream without EOPM. The actual uncompressed size
-    will be available to the caller via the uncomp_size pointer.
-    
-    One missing thing is that the LZMA layer doesn't inform the LZ layer
-    when the encoding is finished and thus the LZ may read more input
-    when it won't be used. However, this doesn't matter if encoding is
-    done with a single call (which is the planned use case for now).
-    For proper multi-call encoding this should be improved.
-    
-    This commit only adds the functionality for internal use.
-    Nothing uses it yet.

-    Scripts: Fix exit status of xzgrep.
-    
-    Omit the -q option from xz, gzip, and bzip2. With xz this shouldn't
-    matter. With gzip it's important because -q makes gzip replace SIGPIPE
-    with exit status 2. With bzip2 it's important because with -q bzip2
-    is completely silent if input is corrupt while other decompressors
-    still give an error message.
-    
-    Avoiding exit status 2 from gzip is important because bzip2 uses
-    exit status 2 to indicate corrupt input. Before this commit xzgrep
-    didn't recognize corrupt .bz2 files because xzgrep was treating
-    exit status 2 as SIGPIPE for gzip compatibility.
-    
-    zstd still needs -q because otherwise it is noisy in normal
-    operation.
-    
-    The code to detect real SIGPIPE didn't check if the exit status
-    was due to a signal (>= 128) and so could ignore some other exit
-    status too.

-    Scripts: Fix exit status of xzdiff/xzcmp.
-    
-    This is a minor fix since this affects only the situation when
-    the files differ and the exit status is something else than 0.
-    In such case there could be SIGPIPE from a decompression tool
-    and that would result in exit status of 2 from xzdiff/xzcmp
-    while the correct behavior would be to return 1 or whatever
-    else diff or cmp may have returned.
+    liblzma: Suppress -Wunused-function warning.
     
-    This commit omits the -q option from xz/gzip/bzip2/lzop arguments.
-    I'm not sure why the -q was used in the first place, perhaps it
-    hides warnings in some situation that I cannot see at the moment.
-    Hopefully the removal won't introduce a new bug.
+    Clang 16.0.0 and earlier have a bug that the ifunc resolver function
+    triggers the -Wunused-function warning. The resolver function is static
+    and only "used" by the __attribute__((__ifunc()__)).
     
-    With gzip the -q option was harmful because it made gzip return 2
-    instead of >= 128 with SIGPIPE. Ignoring exit status 2 (warning
-    from gzip) isn't practical because bzip2 uses exit status 2 to
-    indicate corrupt input file. It's better if SIGPIPE results in
-    exit status >= 128.
+    At this time, the bug is still unresolved, but has been reported:
+    https://github.com/llvm/llvm-project/issues/63957
     
-    With bzip2 the removal of -q seems to be good because with -q
-    it prints nothing if input is corrupt. The other tools aren't
-    silent in this situation even with -q. On the other hand, if
-    zstd support is added, it will need -q since otherwise it's
-    noisy in normal situations.
-    
-    Thanks to Étienne Mollier and Sebastian Andrzej Siewior.
+    This is not a problem in GCC.

-    liblzma: Make lzma_outq usable for threaded decompression too.
-    
-    Before this commit all output queue buffers were allocated as
-    a single big allocation. Now each buffer is allocated separately
-    when needed. Used buffers are cached to avoid reallocation
-    overhead but the cache will keep only one buffer size at a time.
-    This should make things work OK in the decompression where most
-    of the time the buffer sizes will be the same but with some less
-    common files the buffer sizes may vary.
+    liblzma: Reword lzma_str_list_filters() documentation.
     
-    While this should work fine, it's still a bit preliminary
-    and may even get reverted if it turns out to be useless for
-    decompression.
+    This further improves the documentation from commit
+    f36ca7982f6bd5e9827219ed4f3c5a1fbf5d7bdf. The previous wording of
+    "supported options" was slightly misleading since the options that are

+    
+    The comment used "flag" when referring to decoder options. Just

-    liblzma: Enable Intel CET in x86 CRC assembly codes
-    
-    When Intel CET is enabled, we need to include <cet.h> in assembly codes
-    to mark Intel CET support and add _CET_ENDBR to indirect jump targets.
+    xz: Translate the second "%s: " in message.c since French needs "%s : ".
     
-    Tested on Intel Tiger Lake under CET enabled Linux.
+    This string is used to print a filename when using "xz -v" and

-    CMake: Fix compatibility with CMake 3.13.
+    Docs: Add a new section to INSTALL for Tests.
     
-    The syntax "if(DEFINED CACHE{FOO})" requires CMake 3.14.
-    In some other places the code treats the cache variables
-    like normal variables already (${FOO} or if(FOO) is used,
-    not ${CACHE{FOO}).
+    The new Tests section describes basic information about the tests, how
+    to run them, and important details when cross compiling. We have had a
+    few questions about how to compile the tests without running them, so
+    hopefully this information will help others with the same question in the
+    future.
     
-    Thanks to ygrek for reporting the bug on IRC.

-    xz man page: Change \- (minus) to \(en (en-dash) for a numeric range.
+    xz: Add a new --filters-help option.
     
-    Docs of ancient troff/nroff mention \(em (em-dash) but not \(en
-    and \- was used for both minus and en-dash. I don't know how
-    portable \(en is nowadays but it can be changed back if someone
-    complains. At least GNU groff and OpenBSD's mandoc support it.
+    The --filters-help can be used to help create filter chains with the
+    --filters and --filtersX options. The message in --long-help is too
+    short to fully explain the syntax to construct complex filter chains.
     
-    Thanks to Bjarni Ingi Gislason for the patch.
+    In --robot mode, xz will only print the output from liblzma function
+    lzma_str_list_filters.

+    If a filter chain is set but not used in --block-list, it introduced

-    Signed-off-by: Bjarni Ingi Gislason <bjarniig@rhi.hi.is>
+    When opt_block_size is not used, the Block size for mt encoder is
+    derived from the minimum of the largest Block specified by
+    --block-list and the recommended Block size on all filter chains
+    calculated by lzma_mt_block_size(). This avoids using unnecessary

+    xz: Allows --block-list filters to scale down memory usage.
     
-    Signed-off-by: Bjarni Ingi Gislason <bjarniig@rhi.hi.is>
+    Previously, only the default filter chain could have its memory usage
+    adjusted. The filter chains specified with --filtersX were not checked
+    for memory usage. Now, all used filter chains will be adjusted if
+    necessary.

-    Typo fixes from fossies.org.
+    xz: Do not include block splitting if encoders are disabled.
     
-    https://fossies.org/linux/misc/xz-5.2.5.tar.xz/codespell.html
+    The block splitting logic and split_block() function are not needed if
+    encoders are disabled. This will help slightly reduce the binary size
+    when built without encoders and allow split_block() to use functions
+    that require encoders being enabled.

+    This will only free filter chains created with --filters1-9 since the

-    README: Mention that man pages can be translated.
+    xz: Create command line options for filters[1-9].
+    
+    The new command line options are meant to be combined with --block-list.
+    They work as an optional extension to --block-list to specify a custom
+    filter chain for each block listed. The new options allow the creation
+    of up to 9 reusable filter chains. For instance:
+    
+    xz --block-list=1:10MiB,3:5MiB,,2:5MiB,1:0 --filters1=delta--lzma2 \
+    --filters2=x86--lzma2 --filters3=arm64--lzma2
+    
+    Will create the following blocks:
+    1. A block of size 10 MiB with filter chain delta, lzma2.
+    2. A block of size 5 MiB with filter chain arm64, lzma2.
+    3. A block of size 5 MiB with filter chain arm64, lzma2.
+    4. A block of size 5 MiB with filter chain x86, lzma2.
+    5. A block containing the rest of the file contents with filter chain
+       delta, lzma2.

+    Tests: Improve feature testing for skipping.
+    
+    Fixed a bug where test_compress_* would all fail if arm64 or armthumb
+    filters were enabled for compression but arm was disabled. Since the
+    grep tests only checked for "define HAVE_ENCODER_ARM", this would match
+    on HAVE_ENCODER_ARM64 or HAVE_ENCODER_ARMTHUMB.
+    
+    Now the config.h feature test requires " 1" at the end to prevent the
+    prefix problem. have_feature() was also updated for this even though
+    there were known current bugs affecting it. This is just in case future
+    features have a similar prefix problem.

-    Build: Fix bugs in the CMake files.
+    liblzma: Prevent uninitialzed warning in mt stream encoder.
     
-    Seems that the phrase "add more quotes" from sh/bash scripting
-    applies to CMake as well. E.g. passing an unquoted list ${FOO}
-    to a function that expects one argument results in only the
-    first element of the list being passed as an argument and
-    the rest get ignored. Adding quotes helps ("${FOO}").
+    This change only impacts the compiler warning since it was impossible
+    for the wait_abs struct in stream_encode_mt() to be used before it was
+    initialized since mythread_condtime_set() will always be called before
+    mythread_cond_timedwait().
     
-    list(INSERT ...) is weird. Inserting an empty string to an empty
-    variable results in empty list, but inserting it to a non-empty
-    variable does insert an empty element to the list.
+    Since the mythread.h code is different between the POSIX and
+    Windows versions, this warning was only present on Windows builds.
     
-    Since INSERT requires at least one element,
-    "${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt.
-    It might result in an empty element in the list. It seems to not
-    matter as empty elements consistently get ignored in that variable.
-    In fact, calling cmake_check_push_state() and cmake_check_pop_state()
-    will strip the empty elements from CMAKE_REQUIRED_LIBRARIES!
+    Thanks to Arthur S for reporting the warning and providing an initial
+    patch.

+
+    liblzma: Prevent warning for MSYS2 Windows build.
     
-    In addition to quoting fixes, this fixes checks for the cache
-    variables in tuklib_cpucores.cmake and tuklib_physmem.cmake.
+    In lzma_memcmplen(), the <intrin.h> header file is only included if
+    _MSC_VER and _M_X64 are both defined but _BitScanForward64() was
+    previously used if _M_X64 was defined. GCC for MSYS2 defines _M_X64 but
+    not _MSC_VER so _BitScanForward64() was used without including
+    <intrin.h>.
     
-    Thanks to Martin Matuška for testing and reporting the problems.
-    These fixes aren't tested yet but hopefully they soon will be.
+    Now, lzma_memcmplen() will use __builtin_ctzll() for MSYS2 GCC builds as
+    expected.

-    Build: Add very limited experimental CMake support.
+    CI: Add test with -fsanitize=address,undefined.
     
-    This does *NOT* replace the Autotools-based build system in
-    the foreseeable future. See the comment in the beginning
-    of CMakeLists.txt.
+    ci_build.sh was updated to accept disabling of __attribute__ ifunc
+    and CLMUL. This will allow -fsanitize=address to pass because ifunc
+    is incompatible with -fsanitize=address. The CLMUL implementation has
+    optimizations that potentially read past the buffer and mask out the
+    unwanted bytes.
     
-    So far this has been tested only on GNU/Linux but I commit
-    it anyway to make it easier for others to test. Since I
-    haven't played much with CMake before, it's likely that
-    there are things that have been done in a silly or wrong
-    way and need to be fixed.
+    This test will only run on Autotools Linux.

-    
-    tuklib_cpucores.c and tuklib_physmem.c don't include <sys/types.h>
-    even via other files in this package, so clearly that header isn't
-    needed in the tests either (no one has reported build problems due

-    liblzma: Add more uses of lzma_memcmplen() to the normal mode of LZMA.
+    CMake: Rename CHECK_ATTR_IFUNC to ALLOW_ATTR_IFUNC.
     
-    This gives a tiny encoder speed improvement. This could have been done
-    in 2014 after the commit 544aaa3d13554e8640f9caf7db717a96360ec0f6 but
-    it was forgotten.
+    It's so that there's a clear difference in wording compared
+    to liblzma's integrity check types.

-    Build: Add visibility.m4 from gnulib.
+    liblzma: Add ifunc implementation to crc64_fast.c.
+    
+    The ifunc method avoids indirection via the function pointer
+    crc64_func. This works on GNU/Linux and probably on FreeBSD too.
+    The previous __attribute((__constructor__)) method is kept for
+    compatibility with ELF platforms which do support ifunc.
     
-    Appears that this file used to get included as a side effect of
-    gettext. After the change to gettext version requirements this file
-    no longer got copied to the package and so the build was broken.
+    The ifunc method has some limitations, for example, building
+    liblzma with -fsanitize=address will result in segfaults.
+    The configure option --disable-ifunc must be used for such builds.
+    
+    Thanks to Hans Jansen for the original patch.
+    Closes: https://github.com/tukaani-project/xz/pull/53

-    The __builtin byteswapping is the preferred one so check for it first.

-    Revert the previous commit and add a comment.
+    CMake: Protects against double find_package
     
-    The previous commit broke crc32_tablegen.c.
+    Boost iostream uses `find_package` in quiet mode and then again uses
+    `find_package` with required. This second call triggers a
+    `add_library cannot create imported target "ZLIB::ZLIB" because another
+    target with the same name already exists.`
     
-    If the whole package is built without config.h (with defines
-    set on the compiler command line) this should still work fine
-    as long as these headers conform to C99 well enough.
+    This can simply be fixed by skipping the alias part on secondary
+    `find_package` runs.

-    This bumps the version requirement from 0.19 (from 2014) to

-    Using only the old AM_GNU_GETTEXT_VERSION results in old

-    Build: Add support for translated man pages using po4a.
-    
-    The dependency on po4a is optional. It's never required to install
-    the translated man pages when xz is built from a release tarball.
-    If po4a is missing when building from xz.git, the translated man
-    pages won't be generated but otherwise the build will work normally.
-    
-    The translations are only updated automatically by autogen.sh and
-    by "make mydist". This makes it easy to keep po4a as an optional
-    dependency and ensures that I won't forget to put updated
-    translations to a release tarball.
-    
-    The translated man pages aren't installed if --disable-nls is used.
-    
-    The installation of translated man pages abuses Automake internals
-    by calling "install-man" with redefined dist_man_MANS and man_MANS.
-    This makes the hairy script code slightly less hairy. If it breaks
-    some day, this code needs to be fixed; don't blame Automake developers.
-    
-    Also, this adds more quotes to the existing shell script code in
-    the Makefile.am "-hook"s.

-    Build: Workaround a POSIX shell detection problem on Solaris.
-    
-    I don't know if the problem is in gnulib's gl_POSIX_SHELL macro
-    or if xzgrep does something that isn't in POSIX. The workaround
-    adds a special case for Solaris: if /usr/xpg4/bin/sh exists and
-    gl_cv_posix_shell wasn't overriden on the configure command line,
-    use that shell for xzgrep and other scripts. That shell is known
-    to work and exists on most Solaris systems.

-    xz: Limit --memlimit-compress to at most 4020 MiB for 32-bit xz.
-    
-    See the code comment for reasoning. It's far from perfect but
-    hopefully good enough for certain cases while hopefully doing
-    nothing bad in other situations.
-    
-    At presets -5 ... -9, 4020 MiB vs. 4096 MiB makes no difference
-    on how xz scales down the number of threads.
-    
-    The limit has to be a few MiB below 4096 MiB because otherwise
-    things like "xz --lzma2=dict=500MiB" won't scale down the dict
-    size enough and xz cannot allocate enough memory. With
-    "ulimit -v $((4096 * 1024))" on x86-64, the limit in xz had
-    to be no more than 4085 MiB. Some safety margin is good though.
-    
-    This is hack but it should be useful when running 32-bit xz on
-    a 64-bit kernel that gives full 4 GiB address space to xz.
-    Hopefully this is enough to solve this:
-    
-    https://bugzilla.redhat.com/show_bug.cgi?id=1196786
-    
-    FreeBSD has a patch that limits the result in tuklib_physmem()
-    to SIZE_MAX on 32-bit systems. While I think it's not the way
-    to do it, the results on --memlimit-compress have been good. This
-    commit should achieve practically identical results for compression
-    while leaving decompression and tuklib_physmem() and thus
-    lzma_physmem() unaffected.

-    xz: Set the --flush-timeout deadline when the first input byte arrives.
-    
-    xz --flush-timeout=2000, old version:
-    
-      1. xz is started. The next flush will happen after two seconds.
-      2. No input for one second.
-      3. A burst of a few kilobytes of input.
-      4. No input for one second.
-      5. Two seconds have passed and flushing starts.
-    
-    The first second counted towards the flush-timeout even though
-    there was no pending data. This can cause flushing to occur more
-    often than needed.

+    liblzma: Slightly rewords lzma_str_list_filters() documentation.
     
-      1. xz is started.
-      2. No input for one second.
-      3. A burst of a few kilobytes of input. The next flush will
-         happen after two seconds counted from the time when the
-         first bytes of the burst were read.
-      4. No input for one second.
-      5. No input for another second.
-      6. Two seconds have passed and flushing starts.
+    Reword "options required" to "supported options". The previous may have
+    suggested that the options listed were all required anytime a filter is
+    used for encoding or decoding. The reword makes this more clear that
+    adjusting the options is optional.

-    xz: coder.c: Make writing output a separate function.
+    liblzma: Exports lzma_mt_block_size() as an API function.
+    
+    The lzma_mt_block_size() was previously just an internal function for
+    the multithreaded .xz encoder. It is used to provide a recommended Block
+    size for a given filter chain.
     
-    The same code sequence repeats so it's nicer as a separate function.
-    Note that in one case there was no test for opt_mode != MODE_TEST,
-    but that was only because that condition would always be true, so
-    this commit doesn't change the behavior there.
+    This function is helpful to determine the maximum Block size for the
+    multithreaded .xz encoder when one wants to change the filters between
+    blocks. Then, this determined Block size can be provided to
+    lzma_stream_encoder_mt() in the lzma_mt options parameter when
+    intializing the coder. This requires one to know all the filter chains
+    they are using before starting to encode (or at least the filter chain
+    that will need the largest Block size), but that isn't a bad limitation.

-    xz: Fix semi-busy-waiting in xz --flush-timeout.
+    liblzma: Creates IS_ENC_DICT_SIZE_VALID() macro.
     
-    When input blocked, xz --flush-timeout=1 would wake up every
-    millisecond and initiate flushing which would have nothing to
-    flush and thus would just waste CPU time. The fix disables the
-    timeout when no input has been seen since the previous flush.
+    This creates an internal liblzma macro to test if the dictionary size
+    is valid for encoding.

-    Using the aligned methods requires more care to ensure that

-    prefix from the unaligned methods which in liblzma are used in

+    Also, this has >= instead of == since ints larger than 32 bits would

+
+    Windows: Include <intrin.h> when needed.
     
-    Add a configure option --enable-unsafe-type-punning to get the
-    old non-conforming memory access methods. It can be useful with
-    old compilers or in some other less typical situations but
-    shouldn't normally be used.
+    Legacy Windows did not need to #include <intrin.h> to use the MSVC
+    intrinsics. Newer versions likely just issue a warning, but the MSVC
+    documentation says to include the header file for the intrinsics we use.
     
-    Omit the packed struct trick for unaligned access. While it's
-    best in some cases, this is simpler. If the memcpy trick doesn't
-    work, one can request unsafe type punning from configure.
+    GCC and Clang can "pretend" to be MSVC on Windows, so extra checks are
+    needed in tuklib_integer.h to only include <intrin.h> when it will is
+    actually needed.

+
+    tuklib_integer: Use __builtin_clz() with Clang.
     
-    Because CRC32/CRC64 code needs fast aligned reads, if no very
-    safe way to do it is found, type punning is used as a fallback.
-    This sucks but since it currently works in practice, it seems to
-    be the least bad option. It's never needed with GCC >= 4.7 or
-    Clang >= 3.6 since these support __builtin_assume_aligned and
-    thus fast aligned access can be done with the memcpy trick.
+    Clang has support for __builtin_clz(), but previously Clang would
+    fallback to either the MSVC intrinsic or the regular C code. This was
+    discovered due to a bug where a new version of Clang required the
+    <intrin.h> header file in order to use the MSVC intrinsics.
     
-    Other things:
-      - Support GCC/Clang __builtin_bswapXX
-      - Cleaner bswap fallback macros
-      - Minor cleanups
+    Thanks to Anton Kochkov for notifying us about the bug.

-    Scripts: Put /usr/xpg4/bin to the beginning of PATH on Solaris.

-    This adds a configure option --enable-path-for-scripts=PREFIX

-    to make POSIX grep and others available. The Solaris case had
-    been documented in INSTALL with a manual fix but it's better

-    liblzma: Add a comment.

+    The thread method is now configurable for the CMake build. It matches

+    OFF (no threading), posix, win95, and vista. If both Windows and
+    posix threading are both available, then ON will choose Windows

+    target_link_libraries(liblzma Threads::Threads)
+    
+    since on systems like MinGW-w64 it would link the posix threads

+    CI: Change ci_build.sh to use bash instead of sh.
     
-    Now the public API has eight LZMA_RET_INTERNALx members and
-    LZMA_TIMED_OUT is #defined to LZMA_RET_INTERNAL1. This way
-    the code is cleaner overall although the public API has a few
-    extra mysterious enum members.
+    This script is only meant to be run as part of the CI build/test process

+    need to be replaced with a more portable option. For now, it is

-    Or any off_t which isn't very big (like signed 64 bit integer

-    xz: Cleanup io_seek_src() a bit.
-    
-    lseek() returns -1 on error and checking for -1 is nicer.

-    Tests: Remove a duplicate branch from tests/tests.h.
+    Build: Fix --disable-threads breaking the building of shared libs.
     
-    The duplication was introduced about eleven years ago and
-    should have been cleaned up back then already.
+    This is broken in the releases 5.2.6 to 5.4.2. A workaround
+    for these releases is to pass EGREP='grep -E' as an argument
+    to configure in addition to --disable-threads.
     
-    This was caught by -Wduplicated-branches.
+    The problem appeared when m4/ax_pthread.m4 was updated in
+    the commit 6629ed929cc7d45a11e385f357ab58ec15e7e4ad which
+    introduced the use of AC_EGREP_CPP. AC_EGREP_CPP calls
+    AC_REQUIRE([AC_PROG_EGREP]) to set the shell variable EGREP
+    but this was only executed if POSIX threads were enabled.
+    Libtool code also has AC_REQUIRE([AC_PROG_EGREP]) but Autoconf
+    omits it as AC_PROG_EGREP has already been required earlier.
+    Thus, if not using POSIX threads, the shell variable EGREP
+    would be undefined in the Libtool code in configure.
+    
+    ax_pthread.m4 is fine. The bug was in configure.ac which called
+    AX_PTHREAD conditionally in an incorrect way. Using AS_CASE
+    ensures that all AC_REQUIREs get always run.
+    
+    Thanks to Frank Busse for reporting the bug.
+    Fixes: https://github.com/tukaani-project/xz/issues/45

-    liblzma: Use unaligned_readXXne functions instead of type punning.
+commit 55ba6e93004842ae0a0792214a23504267ad8f43
+Author: Jia Tan <jiat0218@gmail.com>
+Date:   2023-03-16 21:38:32 +0800
+
+    liblzma: Add set lzma.h as the main page for Doxygen documentation.
+    
+    The \mainpage command is used in the first block of comments in lzma.h.
+    This changes the previously nearly empty index.html to use the first
+    comment block in lzma.h for its contents.
     
-    Now gcc -fsanitize=undefined should be clean.
+    lzma.h is no longer documented separately, but this is for the better
+    since lzma.h only defined a few macros that users do not need to use.
+    The individual API header files all have a disclaimer that they should
+    not be #included directly, so there should be no confusion on the fact
+    that lzma.h should be the only header used by applications.
     
-    Thanks to Jeffrey Walton.
+    Additionally, the note "See ../lzma.h for information about liblzma as
+    a whole." was removed since lzma.h is now the main page of the
+    generated HTML and does not have its own page anymore. So it would be
+    confusing in the HTML version and was only a "nice to have" when
+    browsing the source files.

-    tuklib_integer: Autodetect support for unaligned access on ARM.
+    Build: Generate doxygen documentation in autogen.sh.
     
-    The result is used as the default for --enable-unaligned-access.
-    The test should work with GCC and Clang.
+    Another command line option (--no-doxygen) was added to disable
+    creating the doxygen documenation in cases where it not wanted or
+    if the doxygen tool is not installed.

-    tuklib_integer: Improve unaligned memory access.
+    Build: Create doxygen/update-doxygen script.
     
-    Now memcpy() or GNU C packed structs for unaligned access instead
-    of type punning. See the comment in this commit for details.
+    This is a helper script to generate the Doxygen documentation. It can be
+    run in 'liblzma' or 'internal' mode by setting the first argument. It
+    will default to 'liblzma' mode and only generate documentation for the
+    liblzma API header files.
     
-    Avoiding type punning with unaligned access is needed to
-    silence gcc -fsanitize=undefined.
+    The helper script will be run during the custom mydist hook when we
+    create releases. This hook already alters the source directory, so its
+    fine to do it here too. This way, we can include the Doxygen generated
+    files in the distrubtion and when installing.
     
-    New functions: unaliged_readXXne and unaligned_writeXXne where
-    XX is 16, 32, or 64.
+    In 'liblzma' mode, the JavaScript is stripped from the .html files and
+    the .js files are removed. This avoids license hassle from jQuery and
+    other libraries that Doxygen 1.9.6 puts into jquery.js in minified form.

-    liblzma: Avoid memcpy(NULL, foo, 0) because it is undefined behavior.
+    Build: Install Doxygen docs and include in distribution if generated.
     
-    I should have always known this but I didn't. Here is an example
-    as a reminder to myself:
+    Added a install-data-local target to install the Doxygen documentation
+    only when it has been generated. In order to correctly remove the docs,
+    a corresponding uninstall-local target was added.
     
-        int mycopy(void *dest, void *src, size_t n)
-        {
-            memcpy(dest, src, n);
-            return dest == NULL;
-        }
+    If the doxygen docs exist in the source tree, they will also be included
+    in the distribution now too.

+
+    Doxygen: Refactor Doxyfile.in to doxygen/Doxyfile.
     
-    In the example, a compiler may assume that dest != NULL because
-    passing NULL to memcpy() would be undefined behavior. Testing
-    with GCC 8.2.1, mycopy(NULL, NULL, 0) returns 1 with -O0 and -O1.
-    With -O2 the return value is 0 because the compiler infers that
-    dest cannot be NULL because it was already used with memcpy()
-    and thus the test for NULL gets optimized out.
+    Instead of having Doxyfile.in configured by Autoconf, the Doxyfile
+    can have the tags that need to be configured piped into the doxygen
+    command through stdin with the overrides after Doxyfile's contents.
     
-    In liblzma, if a null-pointer was passed to memcpy(), there were
-    no checks for NULL *after* the memcpy() call, so I cautiously
-    suspect that it shouldn't have caused bad behavior in practice,
-    but it's hard to be sure, and the problematic cases had to be
-    fixed anyway.
+    Going forward, the documentation should be generated in two different
+    modes: liblzma or internal.
+    
+    liblzma is useful for most users. It is the documentation for just
+    the liblzma API header files. This is the default.
     
-    Thanks to Jeffrey Walton.
+    internal is for people who want to understand how xz and liblzma work.
+    It might be useful for people who want to contribute to the project.

-    xz: In xz -lvv look at the widths of the check names too.
+    xz: Simplify the error-label in Capsicum sandbox code.
     
-    Now the widths of the check names is used to adjust the width
-    of the Check column. This way there no longer is a need to restrict
-    the widths of the check names to be at most ten terminal-columns.
+    Also remove unneeded "sandbox_allowed = false;" as this code
+    will never be run more than once (making it work with multiple
+    input files isn't trivial).

-    Update THANKS.
+    Revert: "Add warning if Capsicum sandbox system calls are unsupported."
+    
+    The warning causes the exit status to be 2, so this will cause problems
+    for many scripted use cases for xz. The sandbox usage is already very
+    limited already, so silently disabling this allows it to be more usable.

+    liblzma: Clarify lzma_lzma_preset() documentation in lzma12.h.

+    lzma_lzma_preset() does not guarentee that the lzma_options_lzma are

+    is built with default configurations, then the options will always be

-    XZ Utils is now part of the Translation Project
-    <https://translationproject.org/>.
+    The documentation was updated to reflect this complexity, since this
+    behavior was unclear before.

+    liblzma: Shorten return description for two functions in filter.h.
     
-    I understood that if a WTPV is specified, it's often wrong
-    because different VS installations have different SDK version
-    installed. Omitting the WTPV tag makes VS2017 default to
-    Windows SDK 8.1 which often is also missing, so in any case
-    people may need to specify the WTPV before building. But some
-    day in the future a missing WTPV tag will start to default to
-    the latest installed SDK which sounds reasonable:
+    Shorten the description for lzma_raw_encoder_memusage() and
+    lzma_raw_decoder_memusage().

+    liblzma: Improve documentation in filter.h.
     
-    https://developercommunity.visualstudio.com/content/problem/140294/windowstargetplatformversion-makes-it-impossible-t.html
+    All functions now explicitly specify parameter and return values.
+    The notes and code annotations were moved before the parameter and
+    return value descriptions for consistency.
     
-    Thanks to "dom".
+    Also, the description above lzma_filter_encoder_is_supported() about
+    not being able to list available filters was removed since
+    lzma_str_list_filters() will do this.

-    xz: Fix a crash in progress indicator when in passthru mode.
+    liblzma: Avoid null pointer + 0 (undefined behavior in C).
+    
+    In the C99 and C17 standards, section 6.5.6 paragraph 8 means that
+    adding 0 to a null pointer is undefined behavior. As of writing,
+    "clang -fsanitize=undefined" (Clang 15) diagnoses this. However,
+    I'm not aware of any compiler that would take advantage of this
+    when optimizing (Clang 15 included). It's good to avoid this anyway
+    since compilers might some day infer that pointer arithmetic implies
+    that the pointer is not NULL. That is, the following foo() would then
+    unconditionally return 0, even for foo(NULL, 0):
+    
+        void bar(char *a, char *b);
+    
+        int foo(char *a, size_t n)
+        {
+            bar(a, a + n);
+            return a == NULL;
+        }
+    
+    In contrast to C, C++ explicitly allows null pointer + 0. So if
+    the above is compiled as C++ then there is no undefined behavior
+    in the foo(NULL, 0) call.
+    
+    To me it seems that changing the C standard would be the sane
+    thing to do (just add one sentence) as it would ensure that a huge
+    amount of old code won't break in the future. Based on web searches
+    it seems that a large number of codebases (where null pointer + 0
+    occurs) are being fixed instead to be future-proof in case compilers
+    will some day optimize based on it (like making the above foo(NULL, 0)
+    return 0) which in the worst case will cause security bugs.
+    
+    Some projects don't plan to change it. For example, gnulib and thus
+    many GNU tools currently require that null pointer + 0 is defined:
     
-    "xz -dcfv not_an_xz_file" crashed (all four options are
-    required to trigger it). It caused xz to call
-    lzma_get_progress(&strm, ...) when no coder was initialized
-    in strm. In this situation strm.internal is NULL which leads
-    to a crash in lzma_get_progress().
+        https://lists.gnu.org/archive/html/bug-gnulib/2021-11/msg00000.html
     
-    The bug was introduced when xz started using lzma_get_progress()
-    to get progress info for multi-threaded compression, so the
-    bug is present in versions 5.1.3alpha and higher.
+        https://www.gnu.org/software/gnulib/manual/html_node/Other-portability-assumptions.html
     
-    Thanks to Filip Palian <Filip.Palian@pjwstk.edu.pl> for
-    the bug report.
+    In XZ Utils null pointer + 0 issue should be fixed after this
+    commit. This adds a few if-statements and thus branches to avoid
+    null pointer + 0. These check for size > 0 instead of ptr != NULL
+    because this way bugs where size > 0 && ptr == NULL will likely
+    get caught quickly. None of them are in hot spots so it shouldn't
+    matter for performance.
+    
+    A little less readable version would be replacing
+    
+        ptr + offset
+    
+    with
+    
+        offset != 0 ? ptr + offset : ptr
+    
+    or creating a macro for it:
+    
+        #define my_ptr_add(ptr, offset) \
+                ((offset) != 0 ? ((ptr) + (offset)) : (ptr))
+    
+    Checking for offset != 0 instead of ptr != NULL allows GCC >= 8.1,
+    Clang >= 7, and Clang-based ICX to optimize it to the very same code
+    as ptr + offset. That is, it won't create a branch. So for hot code
+    this could be a good solution to avoid null pointer + 0. Unfortunately
+    other compilers like ICC 2021 or MSVC 19.33 (VS2022) will create a
+    branch from my_ptr_add().
+    
+    Thanks to Marcin Kowalczyk for reporting the problem:

-    Tests: Add a fuzz test program and a config file for OSS-Fuzz.
+    Build: Use only the generic symbol versioning on MicroBlaze.
+    
+    On MicroBlaze, GCC 12 is broken in sense that
+    __has_attribute(__symver__) returns true but it still doesn't
+    support the __symver__ attribute even though the platform is ELF
+    and symbol versioning is supported if using the traditional
+    __asm__(".symver ...") method. Avoiding the traditional method is
+    good because it breaks LTO (-flto) builds with GCC.
+    
+    See also: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101766
+    
+    For now the only extra symbols in liblzma_linux.map are the
+    compatibility symbols with the patch that spread from RHEL/CentOS 7.
+    These require the use of __symver__ attribute or __asm__(".symver ...")
+    in the C code. Compatibility with the patch from CentOS 7 doesn't
+    seem valuable on MicroBlaze so use liblzma_generic.map on MicroBlaze
+    instead. It doesn't require anything special in the C code and thus
+    no LTO issues either.
+    
+    An alternative would be to detect support for __symver__
+    attribute in configure.ac and CMakeLists.txt and fall back
+    to __asm__(".symver ...") but then LTO would be silently broken
+    on MicroBlaze. It sounds likely that MicroBlaze is a special
+    case so let's treat it as a such because that is simpler. If
+    a similar issue exists on some other platform too then hopefully
+    someone will report it and this can be reconsidered.
+    
+    (This doesn't do the same fix in CMakeLists.txt. Perhaps it should
+    but perhaps CMake build of liblzma doesn't matter much on MicroBlaze.
+    The problem breaks the build so it's easy to notice and can be fixed
+    later.)
     
-    Thanks to Bhargava Shastry and Github user pdknsk.
+    Thanks to Vincent Fazio for reporting the problem and proposing
+    a patch (in the end that solution wasn't used):

-    liblzma: Don't verify header CRC32s if building for fuzz testing.
+    liblzma: Very minor API doc tweaks.
     
-    FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION is #defined when liblzma
-    is being built for fuzz testing.
+    Use "member" to refer to struct members as that's the term used
+    by the C standard.
     
-    Most fuzzed inputs would normally get rejected because of incorrect
-    CRC32 and the actual header decoding code wouldn't get fuzzed.
-    Disabling CRC32 checks avoids this problem. The fuzzer program
-    must still use LZMA_IGNORE_CHECK flag to disable verification of
-    integrity checks of uncompressed data.
+    Use lzma_options_delta.dist and such in docs so that in Doxygen's
+    HTML output they will link to the doc of the struct member.
+    
+    Clean up a few trailing white spaces too.

+
+    liblzma: Minor improvements to vli.h.
     
-    In C++11, the `throw()` specifier is deprecated and `noexcept` is
-    preffered instead.
+    Added [out] annotations to parameters that are pointers and can have
+    their value changed. Also added a clarification to lzma_vli_is_valid.

-    Thanks to Melanie Blower (Intel) for the patch.

+    macros do not need to be on consecutive lines in version.h. They can be
+    separated by more whitespace, comments, or even other content, as long

-    
-    It ended up printing an uninitialized char-array when trying to

-    This also changes the column 12 (minimum xz version) to

+    liblzma: Clarify a comment about LZMA_STR_NO_VALIDATION.
+    
+    The flag description for LZMA_STR_NO_VALIDATION was previously confusing
+    about the treatment for filters than cannot be used with .xz format
+    (lzma1) without using LZMA_STR_ALL_FILTERS. Now, it is clear that
+    LZMA_STR_NO_VALIDATION is not a super set of LZMA_STR_ALL_FILTERS.
 
-    liblzma: Add lzma_file_info_decoder().

-    xz: Use POSIX_FADV_RANDOM for in "xz --list" mode.
+    xz: Add SIGTSTP handler for progress indicator time keeping.
+    
+    This way, if xz is stopped the elapsed time and estimated time
+    remaining won't get confused by the amount of time spent in
+    the stopped state.
+    
+    This raises SIGSTOP. It's not clear to me if this is the correct way.
+    POSIX and glibc docs say that SIGTSTP shouldn't stop the process if
+    it is orphaned but this commit doesn't attempt to handle that.
+    
+    Search for SIGTSTP in section 2.4.3:
     
-    xz --list is random access so POSIX_FADV_SEQUENTIAL was clearly
-    wrong.

-    liblzma: Fix lzma_memlimit_set(strm, 0).
-    
-    The 0 got treated specially in a buggy way and as a result
-    the function did nothing. The API doc said that 0 was supposed
-    to return LZMA_PROG_ERROR but it didn't.
-    
-    Now 0 is treated as if 1 had been specified. This is done because
-    0 is already used to indicate an error from lzma_memlimit_get()
-    and lzma_memusage().
+    tuklib_physmem: Check for __has_warning before GCC version.
     
-    In addition, lzma_memlimit_set() no longer checks that the new
-    limit is at least LZMA_MEMUSAGE_BASE. It's counter-productive
-    for the Index decoder and was actually needed only by the
-    auto decoder. Auto decoder has now been modified to check for
-    LZMA_MEMUSAGE_BASE.
+    Clang can be configured to fake a too high GCC version so
+    this way it's more robust.

-    liblzma: Similar memlimit fix for stream_, alone_, and auto_decoder.
+    liblzma: Fix documentation in filter.h for lzma_str_to_filters()
+    
+    The previous documentation for lzma_str_to_filters() was technically
+    correct, but misleading. lzma_str_to_filters() returns NULL on success,
+    which is in practice always defined to 0. This is the same value as
+    LZMA_OK, but lzma_str_to_filters() does not return lzma_ret so we should
+    be more clear.

-    liblzma: Fix handling of memlimit == 0 in lzma_index_decoder().
+    Revert "tuklib_common: Define __has_warning if it is not defined."
     
-    It returned LZMA_PROG_ERROR, which was done to avoid zero as
-    the limit (because it's a special value elsewhere), but using
-    LZMA_PROG_ERROR is simply inconvenient and can cause bugs.
+    This reverts commit 82e3c968bfa10e3ff13333bd9cbbadb5988d6766.
     
-    The fix/workaround is to treat 0 as if it were 1 byte. It's
-    effectively the same thing. The only weird consequence is
-    that then lzma_memlimit_get() will return 1 even when 0 was
-    specified as the limit.
+    Macros in the reserved namespace (_foo or __foo) shouldn't be #defined
+    without a very good reason. Here the alternative would have been
+    to #define tuklib_has_warning(str) to an approriate value.
     
-    This fixes a very rare corner case in xz --list where a specific
-    memory usage limit and a multi-stream file could print the
-    error message "Internal error (bug)" instead of saying that
-    the memory usage limit is too low.
+    Also the tuklib_* files should stay namespace clean if possible.

+    tuklib_physmem: Clean up the way -Wcast-function-type is silenced on Windows.
+    
+    __has_warning and other __has_foo macros are meant to become

+    
+    This also relied on tuklib_common.h for #defining __has_warning

-    tuklib_cpucores: Add support for sched_getaffinity().
-    
-    It's available in glibc (GNU/Linux, GNU/kFreeBSD). It's better
-    than sysconf(_SC_NPROCESSORS_ONLN) because sched_getaffinity()
-    gives the number of cores available to the process instead of
-    the total number of cores online.
+    liblzma: Set documentation on all reserved fields to private.
     
-    As a side effect, this commit fixes a bug on GNU/kFreeBSD where
-    configure would detect the FreeBSD-specific cpuset_getaffinity()
-    but it wouldn't actually work because on GNU/kFreeBSD it requires
-    using -lfreebsd-glue when linking. Now the glibc-specific function
-    will be used instead.
+    This prevents the reserved fields from being part of the generated
+    Doxygen documentation.

+    Doxygen: Update Doxyfile.in from 1.4.7 to 1.8.17.
     
-    Thanks to Sebastian Andrzej Siewior for the original patch
-    and testing.
+    A few Doxygen tags were obsolete from 1.4.7. Version 1.8.17 released
+    in 2019, so this should be compatible with resonable modern distros.
+    The purpose of Doxygen these days is for docs on the website, so it
+    doesn't necessarily have to work for everyone. Just when the maintainers
+    want to update the docs.

-    xz: Fix copying of timestamps on Windows.
+    Doxygen: Make Doxygen only produce liblzma API documentation by default.
     
-    xz used to call utime() on Windows, but its result gets lost
-    on close(). Using _futime() seems to work.
+    Doxygen is now configurable in autotools only with
+    --enable-doxygen=[api|all]. The default is "api", which will only
+    generate HTML output for liblzma API functions. The LaTex documentation
+    output was also disabled.

-    xz: Silence warnings from -Wlogical-op.
+    tuklib_physmem: Silence warning from -Wcast-function-type on MinGW-w64.
     
-    Thanks to Evan Nemerson.
+    tuklib_physmem depends on GetProcAddress() for both MSVC and MinGW-w64
+    to retrieve a function address. The proper way to do this is to cast the
+    return value to the type of function pointer retrieved. Unfortunately,
+    this causes a cast-function-type warning, so the best solution is to
+    simply ignore the warning.

-    Build: Bump GNU Gettext version requirement to 0.19.

-    It silences a few warnings and most people probably have
-    0.19 even on stable distributions.
+    The 32-bit build needs to be first so the configure cache only needs to
+    be reset one time. The 32-bit build sets the CFLAGS env variable, so any
+    build using that flag after will fail unless the cache is reset.

-    liblzma: Disable external SHA-256 by default.
-    
-    This is the sane thing to do. The conflict with OpenSSL
-    on some OSes and especially that the OS-provided versions
-    can be significantly slower makes it clear that it was
-    a mistake to have the external SHA-256 support enabled by
-    default.
-    
-    Those who want it can now pass --enable-external-sha256 to
-    configure. INSTALL was updated with notes about OSes where
-    this can be a bad idea.
-    
-    The SHA-256 detection code in configure.ac had some bugs that
-    could lead to a build failure in some situations. These were
-    fixed, although it doesn't matter that much now that the
-    external SHA-256 is disabled by default.

+
+    xz: Do not set compression settings with raw format in list mode.
     
-    MINIX >= 3.2.0 uses NetBSD's libc and thus has SHA256_Init
-    in libc instead of libutil. Support for the libutil version
-    was removed.
+    Calling coder_set_compression_settings() in list mode with verbose mode
+    on caused the filter chain and memory requirements to print. This was
+    unnecessary since the command results in an error and not consistent
+    with other formats like lzma and alone.

-    Build: Avoid SHA256_Init on FreeBSD and MINIX 3.
-    
-    On FreeBSD 10 and older, SHA256_Init from libmd conflicts
-    with libcrypto from OpenSSL. The OpenSSL version has
-    different sizeof(SHA256_CTX) and it can cause weird
-    problems if wrong SHA256_Init gets used.
+    CI: Disable shared and nls from various jobs in autotool runners.
     
-    Looking at the source, MINIX 3 seems to have a similar issue but
-    I'm not sure. To be safe, I disabled SHA256_Init on MINIX 3 too.
+    Disabling shared library generation and linking should help speed up the
+    runners. The shared library is still being tested in the 32 bit build
+    and the full feature.
     
-    NetBSD has SHA256_Init in libc and they had a similar problem,
-    but they already fixed it in 2009.
+    Disabling nls is to check for any unexpected warnings or errors.

-    xz: Make xz buildable even when encoders or decoders are disabled.
+    Build: Make configure add more warning flags for GCC and Clang.
     
-    The patch is quite long but it's mostly about adding new #ifdefs
-    to omit code when encoders or decoders have been disabled.
+    -Wstrict-aliasing was removed from the list since it is enabled
+    by -Wall already.
     
-    This adds two new #defines to config.h: HAVE_ENCODERS and
-    HAVE_DECODERS.
+    A normal build is clean with these on GNU/Linux x86-64 with
+    GCC 12.2.0 and Clang 14.0.6.

-    Build: Build LZMA1/2 presets also when only decoder is wanted.
+    Tests: Fix warnings from clang --Wassign-enum.
     
-    People shouldn't rely on the presets when decoding raw streams,
-    but xz uses the presets as the starting point for raw decoder
-    options anyway.
+    Explicitly casting the integer to lzma_check silences the warning.
+    Since such an invalid value is needed in multiple tests, a constant
+    INVALID_LZMA_CHECK_ID was added to tests.h.
     
-    lzma_encocder_presets.c was renamed to lzma_presets.c to
-    make it clear it's not used solely by the encoder code.
+    The use of 0x1000 for lzma_block.check wasn't optimal as if
+    the underlying type is a char then 0x1000 will be truncated to 0.
+    However, in these test cases the value is ignored, thus even with
+    such truncation the test would have passed.

-    Build: Fix configure to handle LZMA1 dependency with LZMA2.
+    Tests: Silence warnings from -Wsign-conversion.
     
-    Now it gives an error if LZMA1 encoder/decoder is missing
-    when LZMA2 encoder/decoder was requested. Even better would
-    be LZMA2 implicitly enabling LZMA1 but it would need more code.
+    Note that assigning an unsigned int to lzma_check doesn't warn
+    on GNU/Linux x86-64 since the enum type is unsigned on that
+    platform. The enum can be signed on some other platform though
+    so it's best to use enumeration type lzma_check in these situations.

-    Build: Don't omit lzma_cputhreads() unless using --disable-threads.
+    liblzma: Silence warnings from clang -Wconditional-uninitialized.
     
-    Previously it was omitted if encoders were disabled
-    with --disable-encoders. It didn't make sense and
-    it also broke the build.
+    This is similar to 2ce4f36f179a81d0c6e182a409f363df759d1ad0.
+    The actual initialization of the variables is done inside

+    the initialization code inside the macro is always executed.

-    liblzma: Fix a memory leak in error path of lzma_index_dup().
-    
-    lzma_index_dup() calls index_dup_stream() which, in case of
-    an error, calls index_stream_end() to free memory allocated
-    by index_stream_init(). However, it illogically didn't
-    actually free the memory. To make it logical, the tree
-    handling code was modified a bit in addition to changing
-    index_stream_end().
+    Tests: Fix type-limits warning in test_filter_flags.
     
-    Thanks to Evan Nemerson for the bug report.
+    This only occurs in test_filter_flags when the BCJ filters are not
+    configured and built. In this case, ARRAY_SIZE() returns 0 and causes a
+    type-limits warning with the loop variable since an unsigned number will
+    always be >= 0.

-    Update NEWS for 5.2.2.
+    liblzma: CLMUL CRC64: Work around a bug in MSVC, second attempt.
+    
+    This affects only 32-bit x86 builds. x86-64 is OK as is.
+    
+    I still cannot easily test this myself. The reporter has tested
+    this and it passes the tests included in the CMake build and
+    performance is good: raw CRC64 is 2-3 times faster than the
+    C version of the slice-by-four method. (Note that liblzma doesn't
+    include a MSVC-compatible version of the 32-bit x86 assembly code
+    for the slice-by-four method.)
+    
+    Thanks to Iouri Kharon for figuring out a fix, testing, and
+    benchmarking.

-    Update German translation, mostly wrt orthography
+    CI/CD: Add 32-bit build and test steps to Ubuntu autotools runner.
     
-    Provide an update of the German translation.
-    * A lot of compound words were previously written with spaces, while
-      German orthography is relatively clear in that the components
-      should not be separated.
-    * When referring to the actual process of (de)compression rather than the
-      concept, replace “(De-)Kompression” with “(De-)Komprimierung”.
-      Previously, both forms were used in this context and are now used in a
-      manner consistent with “Komprimierung” being more likely to refer to
-      a process.
-    * Consistently translate “standard input”/“output”
-    * Use “Zeichen” instead of false friend “Charakter” for “character”
-    * Insert commas around relative clauses (as required in German)
-    * Some other minor corrections
-    * Capitalize “ß” as “ẞ”
-    * Consistently start option descriptions in --help with capital letters
+    If all goes well, Mac autotools and Linux and Mac CMake will be added
+    later for 32-bit builds.

-    liblzma: A MSVC-specific hack isn't needed with MSVC 2013 and newer.
+    sysdefs.h: Don't include memory.h anymore even if it were available.
+    
+    It quite probably was never needed, that is, any system where memory.h
+    was required likely couldn't compile XZ Utils for other reasons anyway.
+    
+    XZ Utils 5.2.6 and later source packages were generated using
+    Autoconf 2.71 which no longer defines HAVE_MEMORY_H. So the code
+    being removed is no longer used anyway.

-    Windows: Add MSVC project files for building liblzma.
+    CMake: Fix windres issues again.
     
-    Thanks to Adam Walling for creating these files.
+    At least on some systems, GNU windres needs --use-temp-file
+    in addition to the \x20 hack to avoid spaces in the command line
+    argument. Hovever, that \x20 syntax is broken with llvm-windres
+    version 15.0.0 (results in "XZx20Utils") but luckily it works
+    with a regular space. Thus it is best to limit the workarounds
+    to GNU toolchain on Windows.

-    Fix typo in German translation.
+    Tests: test_filter_flags: Clean up minor issues.
     
-    As pointed out by Robert Pollak, there's a typo in the German
-    translation of the compression preset option (-0 ... -9) help text.
-    "The compressor" translates to "der Komprimierer", and the genitive
-    form is "des Komprimierers". The old word makes no sense at all.
+    Here are the list of the most significant issues addressed:
+    - Avoid using internal common.h header. It's not good to copy the
+    constants like this but common.h cannot be included for use outside
+    of liblzma. This is the quickest thing to do that could be fixed later.
+    
+    - Omit the INIT_FILTER macro. Initialization should be done with just
+    regular designated initializers.
+    
+    - Use start_offset = 257 for BCJ tests. It demonstrates that Filter
+    Flags encoder and decoder don't validate the options thoroughly.
+    257 is valid only for the x86 filter. This is a bit silly but
+    not a significant problem in practice because the encoder and
+    decoder initialization functions will catch bad alignment still.
+    Perhaps this should be fixed but it's not urgent and doesn't need
+    to be in 5.4.x.
+    
+    - Various tweaks to comments such as filter id -> Filter ID

-    Revert "xz: Use pipe2() if available."
-    
-    This reverts commit 7a11c4a8e5e15f13d5fa59233b3172e65428efdd.
-    It is a problem when libc has pipe2() but the kernel is too
-    old to have pipe2() and thus pipe2() fails. In xz it's pointless
-    to have a fallback for non-functioning pipe2(); it's better to
-    avoid pipe2() completely.
+    CMake: Update cmake_minimum_required from 3.13...3.16 to 3.13...3.25.

-    xz: Add support for sandboxing with Capsicum.
-    
-    The sandboxing is used conditionally as described in main.c.
-    This isn't optimal but it was much easier to implement than
-    a full sandboxing solution and it still covers the most common
-    use cases where xz is writing to standard output. This should
-    have practically no effect on performance even with small files
-    as fork() isn't needed.
-    
-    C and locale libraries can open files as needed. This has been
-    fine in the past, but it's a problem with things like Capsicum.
-    io_sandbox_enter() tries to ensure that various locale-related
-    files have been loaded before cap_enter() is called, but it's
-    possible that there are other similar problems which haven't
-    been seen yet.
+    CMake/Windows: Add resource files to xz.exe and xzdec.exe.
     
-    Currently Capsicum is available on FreeBSD 10 and later
-    and there is a port to Linux too.
+    The command line tools cannot be built with MSVC for now but
+    they can be built with MinGW-w64.
     
-    Thanks to Loganaden Velvindron for help.
+    Thanks to Iouri Kharon for the bug report and the original patch.

-    Fix bugs and otherwise improve ax_check_capsicum.m4.
-    
-    AU_ALIAS was removed because the new version is incompatible
-    with the old version.
-    
-    It no longer checks for <sys/capability.h> separately.
-    It's enough to test for it as part of AC_CHECK_DECL.
-    The defines HAVE_CAPSICUM_SYS_CAPSICUM_H and
-    HAVE_CAPSICUM_SYS_CAPABILITY_H were removed as unneeded.
-    HAVE_SYS_CAPSICUM_H from AC_CHECK_HEADERS is enough.
-    
-    It no longer does a useless search for the Capsicum library
-    if the header wasn't found.
-    
-    Fixed a bug in ACTION-IF-FOUND (the first argument). Specifying
-    the argument omitted the default action but the given action
-    wasn't used instead.
-    
-    AC_DEFINE([HAVE_CAPSICUM]) is now always called when Capsicum
-    support is found. Previously it was part of the default
-    ACTION-IF-FOUND which a custom action would override. Now
-    the default action only prepends ${CAPSICUM_LIB} to LIBS.
-    
-    The documentation was updated.
+    CMake/Windows: Add a workaround for windres from GNU binutils.
     
-    Since there as no serial number, "#serial 2" was added.
+    Thanks to Iouri Kharon for the bug report and the original patch.

+    CI/CD: Split CMake Linux and MacOS build phase to build and test.
     
-    The idea of 99 is that it looks a bit weird in this context.
-    For new features there's no API/ABI stability in devel versions.
+    The phase split was only done for Autotools before, so should also

+    The new PHASE argument can be build, test, or all. all is the default.
+    This way, the CI/CD script can differentiate between the build and test

-    Fix CPU core count detection on QNX.
-    
-    It tried to use sysctl() on QNX but
-      - it broke the build because sysctl() needs -lsocket on QNX;
-      - sysctl() doesn't work for detecting the core count on QNX
-        even if it compiled.
+    Merge pull request #7 from tukaani-project/tuktest_index_hash
     
-    sysconf() works. An alternative would have been to use
-    QNX-specific SYSPAGE_ENTRY(num_cpu) from <sys/syspage.h>.
-    
-    Thanks to Ole André Vadla Ravnås.

-    liblzma: Fix a compression-ratio regression in LZMA1/2 in fast mode.

-    The bug was added in the commit
-    f48fce093b07aeda95c18850f5e086d9f2383380 and thus
-    affected 5.1.4beta and 5.2.0. Luckily the bug cannot
-    cause data corruption or other nasty things.
+    The line in the .vcxproj files for building with was missing in 5.4.0.
+    Thank to Hajin Jang for reporting the issue.

-    xz: Fix the fcntl() usage when creating a pipe for the self-pipe trick.
+    liblzma: Remove common.h include from common/index.h.
     
-    Now it reads the old flags instead of blindly setting O_NONBLOCK.
-    The old code may have worked correctly, but this is better.
+    common/index.h is needed by liblzma internally and tests. common.h will
+    include and define many things that are not needed by the tests. Also,
+    this prevents include order problems because common.h will redefine
+    LZMA_API resulting in a warning.

+    The shell parameter expansion using # and ## is not supported in
+    Solaris 10 Bourne shell (/bin/sh). Even though this is POSIX, it is not fully

-    Add a few casts to tuklib_integer.h to silence possible warnings.

-    I heard that Visual Studio 2013 gave warnings without the casts.
+    5.5.0alpha won't be released, it's just to mark that
+    the branch is not for stable 5.4.x.
     
-    Thanks to Gabi Davar.
+    Once again there is no API/ABI stability for new features
+    in devel versions. The major soname won't be bumped even
+    if API/ABI of new features breaks between devel releases.

-    xz: Don't fail if stdout doesn't support O_NONBLOCK.
-    
-    This is similar to the case with stdin.
-    
-    Thanks to Brad Smith for the bug report and testing
-    on OpenBSD.
+    Tests: test_check: Test corner cases of CLMUL CRC64.

-    xz: Don't fail if stdin doesn't support O_NONBLOCK.
+    liblzma: Includes sys/time.h conditionally in mythread
     
-    It's a problem at least on OpenBSD which doesn't support
-    O_NONBLOCK on e.g. /dev/null. I'm not surprised if it's
-    a problem on other OSes too since this behavior is allowed
-    in POSIX-1.2008.
+    Previously, <sys/time.h> was always included, even if mythread only used
+    clock_gettime. <time.h> is still needed even if clock_gettime is not used
+    though because struct timespec is needed for mythread_condtime.

+
+    Build: No longer require HAVE_DECL_CLOCK_MONOTONIC to always be set.
     
-    The code relying on this behavior was committed in June 2013
-    and included in 5.1.3alpha released on 2013-10-26. Clearly
-    the development releases only get limited testing.
+    Previously, if threading was enabled HAVE_DECL_CLOCK_MONOTONIC would always
+    be set to 0 or 1. However, this macro was needed in xz so if xz was not
+    built with threading and HAVE_DECL_CLOCK_MONOTONIC was not defined but
+    HAVE_CLOCK_GETTIME was, it caused a warning during build. Now,
+    HAVE_DECL_CLOCK_MONOTONIC has been renamed to HAVE_CLOCK_MONOTONIC and
+    will only be set if it is 1.

-    Tests: Don't hide unexpected error messages in test_files.sh.
+    Translations: Add Ukrainian translations of man pages.
     
-    Hiding them makes no sense since normally there's no error
-    when testing the "good" files. With "bad" files errors are
-    expected and then it makes sense to keep the messages hidden.
+    Thanks to Yuri Chornoivan

-    Update Solaris notes in INSTALL.
+    CI/CD: Create initial version of CI/CD workflow.
     
-    Mention the possible "make check" failure on Solaris in the
-    Solaris-specific section of INSTALL. It was already in
-    section 4.5 but it is better mention it in the OS-specific
-    section too.
+    The CI/CD workflow will only execute on Ubuntu and MacOS latest version.
+    The workflow will attempt to build with autotools and CMake and execute
+    the tests. The workflow will run for all pull requests and pushes done
+    to the master branch.

+    liblzma: Fix lzma_microlzma_encoder() return value.
+    
+    Using return_if_error on lzma_lzma_lclppb_encode was improper because
+    return_if_error is expecting an lzma_ret value, but
+    lzma_lzma_lclppb_encode returns a boolean. This could result in
+    lzma_microlzma_encoder, which would be misleading for applications.

-    Bump version and soname for 5.2.0.
-

-    in -version-info to make the soname match the liblzma
-    version anyway. It doesn't hurt anything as long as
-    it doesn't conflict with library versioning rules.
