+## Changelog
+
+### 3.0.0
+
+ - Reduce memory usage for inflate. This changes `struct tinfl_decompressor_tag` and therefore requires a major version bump (breaks ABI compatibility)
+ - Add padding to structures so it continues to work if features differ. This also changes some structures
+ - Use _ftelli64, _fseeki64 and stat with MinGW32 and OpenWatcom
+ - Fix varios warnings with OpenWatcom compiler
+ - Avoid using unaligned memory access in UBSan builds
+ - Set MINIZ_LITTLE_ENDIAN only if not set
+ - Add MINIZ_NO_DEFLATE_APIS and MINIZ_NO_INFLATE_APIS
+ - Fix use of uninitialized memory in tinfl_decompress_mem_to_callback()
+ - Use wfopen on windows
+ - Use _wstat64 instead _stat64 on windows
+ - Use level_and_flags after MZ_DEFAULT_COMPRESSION has been handled
+ - Improve endianess detection
+ - Don't use unaligned stores and loads per default
+ - Fix function declaration if MINIZ_NO_STDIO is used
+ - Fix MZ_ZIP_GENERAL_PURPOSE_BIT_FLAG_UTF8 not being set
+ - Remove total files check (its 32-bit uint)
+ - tinfl_decompress: avoid NULL ptr arithmetic UB
+ - miniz_zip: fix mz_zip_reader_extract_to_heap to read correct sizes
+ - Eliminate 64-bit operations on 32-bit machines
+ - Disable treating warnings as error with MSVC
+ - Disable building shared lib via CMake by default
+ - Fixed alignment problems on MacOS
+ - Fixed get error string for MZ_ZIP_TOTAL_ERRORS
+ - Write correct FLEVEL 2-bit value in zlib header
+ 
+### 2.2.0
+
+ - Fix examples with amalgamation
+ - Modified cmake script to support shared library mode and find_package
+ - Fix for misleading doc comment on `mz_zip_reader_init_cfile` function
+ - Add include location tolerance and stop forcing `_GNU_SOURCE`
+ - Fix: mz_zip_reader_locate_file_v2 returns an mz_bool
+ - Fix large file system checks
+ - Add #elif to enable an external mz_crc32() to be linked in
+ - Write with dynamic size (size of file/data to be added not known before adding)
+ - Added uncompress2 for zlib compatibility
+ - Add support for building as a Meson subproject
+ - Added OSSFuzz support; Integrate with CIFuzz
+ - Add pkg-config file
+ - Fixed use-of-uninitialized value msan error when copying dist bytes with no output bytes written.
+ - mz_zip_validate_file(): fix memory leak on errors
+ - Fixed MSAN use-of-uninitialized in tinfl_decompress when invalid dist is decoded. In this instance dist was 31 which s_dist_base translates as 0
+ - Add flag to set (compressed) size in local file header
+ - avoid use of uninitialized value in tdefl_record_literal
+
+### 2.1.0
+
+ - More instances of memcpy instead of cast and use memcpy per default
+ - Remove inline for c90 support
+ - New function to read files via callback functions when adding them
+ - Fix out of bounds read while reading Zip64 extended information
+ - guard memcpy when n == 0 because buffer may be NULL
+ - Implement inflateReset() function
+ - Move comp/decomp alloc/free  prototypes under guarding #ifndef MZ_NO_MALLOC
+ - Fix large file support under Windows
+ - Don't warn if _LARGEFILE64_SOURCE is not defined to 1

+ - Add !defined check on MINIZ_USE_ALIGNED_LOADS_AND_STORES
+
+### 2.0.8
+
+ - Remove unimplemented functions (mz_zip_locate_file and mz_zip_locate_file_v2)
+ - Add license, changelog, readme and example files to release zip
+ - Fix heap overflow to user buffer in tinfl_status tinfl_decompress
+ - Fix corrupt archive if uncompressed file smaller than 4 byte and the file is added by mz_zip_writer_add_mem*
+
+### 2.0.7
+
+ - Removed need in C++ compiler in cmake build
+ - Fixed a lot of uninitialized value errors found with Valgrind by memsetting m_dict to 0 in tdefl_init

+ - Fix assert with mz_zip_writer_add_mem* w/MZ_DEFAULT_COMPRESSION
+ - cmake build: install library and headers
+ - Remove _LARGEFILE64_SOURCE requirement from apple defines for large files
+
+### 2.0.6
+
+ - Improve MZ_ZIP_FLAG_WRITE_ZIP64 documentation
+ - Remove check for cur_archive_file_ofs > UINT_MAX because cur_archive_file_ofs is not used after this point
+ - Add cmake debug configuration
+ - Fix PNG height when creating png files
+ - Add "iterative" file extraction method based on mz_zip_reader_extract_to_callback.
+ - Option to use memcpy for unaligned data access
+ - Define processor/arch macros as zero if not set to one
+
+### 2.0.4/2.0.5
+
+ - Fix compilation with the various omission compile definitions
+
+### 2.0.3
+
+- Fix GCC/clang compile warnings
+- Added callback for periodic flushes (for ZIP file streaming)
+- Use UTF-8 for file names in ZIP files per default
+
+### 2.0.2
+
+- Fix source backwards compatibility with 1.x
+- Fix a ZIP bit not being set correctly
+
+### 2.0.1
+
+- Added some tests
+- Added CI
+- Make source code ANSI C compatible
+
+### 2.0.0 beta
+
+- Matthew Sitton merged miniz 1.x to Rich Geldreich's vogl ZIP64 changes. Miniz is now licensed as MIT since the vogl code base is MIT licensed
+- Miniz is now split into several files
+- Miniz does now not seek backwards when creating ZIP files. That is the ZIP files can be streamed
+- Miniz automatically switches to the ZIP64 format when the created ZIP files goes over ZIP file limits
+- Similar to [SQLite](https://www.sqlite.org/amalgamation.html) the Miniz source code is amalgamated into one miniz.c/miniz.h pair in a build step (amalgamate.sh). Please use miniz.c/miniz.h in your projects
+- Miniz 2 is only source back-compatible with miniz 1.x. It breaks binary compatibility because structures changed
+
+### v1.16 BETA Oct 19, 2013
+
+Still testing, this release is downloadable from [here](http://www.tenacioussoftware.com/miniz_v116_beta_r1.7z). Two key inflator-only robustness and streaming related changes. Also merged in tdefl_compressor_alloc(), tdefl_compressor_free() helpers to make script bindings easier for rustyzip. I would greatly appreciate any help with testing or any feedback.
+
+The inflator in raw (non-zlib) mode is now usable on gzip or similar streams that have a bunch of bytes following the raw deflate data (problem discovered by rustyzip author williamw520). This version should never read beyond the last byte of the raw deflate data independent of how many bytes you pass into the input buffer.
+
+The inflator now has a new failure status TINFL_STATUS_FAILED_CANNOT_MAKE_PROGRESS (-4). Previously, if the inflator was starved of bytes and could not make progress (because the input buffer was empty and the caller did not set the TINFL_FLAG_HAS_MORE_INPUT flag - say on truncated or corrupted compressed data stream) it would append all 0's to the input and try to soldier on. This is scary behavior if the caller didn't know when to stop accepting output (because it didn't know how much uncompressed data was expected, or didn't enforce a sane maximum). v1.16 will instead return TINFL_STATUS_FAILED_CANNOT_MAKE_PROGRESS immediately if it needs 1 or more bytes to make progress, the input buf is empty, and the caller has indicated that no more input is available. This is a "soft" failure, so you can call the inflator again with more input and it will try to continue, or you can give up and fail. This could be very useful in network streaming scenarios.
+
+- The inflator coroutine func. is subtle and complex so I'm being cautious about this release. I would greatly appreciate any help with testing or any feedback.
+         I feel good about these changes, and they've been through several hours of automated testing, but they will probably not fix anything for the majority of prev. users so I'm
+         going to mark this release as beta for a few weeks and continue testing it at work/home on various things.
+- The inflator in raw (non-zlib) mode is now usable on gzip or similar data streams that have a bunch of bytes following the raw deflate data (problem discovered by rustyzip author williamw520).
+         This version should *never* read beyond the last byte of the raw deflate data independent of how many bytes you pass into the input buffer. This issue was caused by the various Huffman bitbuffer lookahead optimizations, and
+         would not be an issue if the caller knew and enforced the precise size of the raw compressed data *or* if the compressed data was in zlib format (i.e. always followed by the byte aligned zlib adler32).
+         So in other words, you can now call the inflator on deflate streams that are followed by arbitrary amounts of data and it's guaranteed that decompression will stop exactly on the last byte.
+- The inflator now has a new failure status: TINFL_STATUS_FAILED_CANNOT_MAKE_PROGRESS (-4). Previously, if the inflator was starved of bytes and could not make progress (because the input buffer was empty and the
+         caller did not set the TINFL_FLAG_HAS_MORE_INPUT flag - say on truncated or corrupted compressed data stream) it would append all 0's to the input and try to soldier on.
+         This is scary, because in the worst case, I believe it was possible for the prev. inflator to start outputting large amounts of literal data. If the caller didn't know when to stop accepting output
+         (because it didn't know how much uncompressed data was expected, or didn't enforce a sane maximum) it could continue forever. v1.16 cannot fall into this failure mode, instead it'll return
+         TINFL_STATUS_FAILED_CANNOT_MAKE_PROGRESS immediately if it needs 1 or more bytes to make progress, the input buf is empty, and the caller has indicated that no more input is available. This is a "soft"
+         failure, so you can call the inflator again with more input and it will try to continue, or you can give up and fail. This could be very useful in network streaming scenarios.
+- Added documentation to all the tinfl return status codes, fixed miniz_tester so it accepts double minus params for Linux, tweaked example1.c, added a simple "follower bytes" test to miniz_tester.cpp.
+### v1.15 r4 STABLE - Oct 13, 2013
+
+Merged over a few very minor bug fixes that I fixed in the zip64 branch. This is downloadable from [here](http://code.google.com/p/miniz/downloads/list) and also in SVN head (as of 10/19/13).
+
+
+### v1.15 - Oct. 13, 2013
+
+Interim bugfix release while I work on the next major release with zip64 and streaming compression/decompression support. Fixed the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug (thanks kahmyong.moon@hp.com), which could cause the locate files func to not find files when this flag was specified. Also fixed a bug in mz_zip_reader_extract_to_mem_no_alloc() with user provided read buffers (thanks kymoon). I also merged lots of compiler fixes from various github repo branches and Google Code issue reports. I finally added cmake support (only tested under for Linux so far), compiled and tested with clang v3.3 and gcc 4.6 (under Linux), added defl_write_image_to_png_file_in_memory_ex() (supports Y flipping for OpenGL use, real-time compression), added a new PNG example (example6.c - Mandelbrot), and I added 64-bit file I/O support (stat64(), etc.) for glibc.
+
+- Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug (thanks kahmyong.moon@hp.com) which could cause locate files to not find files. This bug
+        would only have occurred in earlier versions if you explicitly used this flag, OR if you used mz_zip_extract_archive_file_to_heap() or mz_zip_add_mem_to_archive_file_in_place()
+        (which used this flag). If you can't switch to v1.15 but want to fix this bug, just remove the uses of this flag from both helper funcs (and of course don't use the flag).
+- Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when pUser_read_buf is not NULL and compressed size is > uncompressed size
+- Fixing mz_zip_reader_extract_*() funcs so they don't try to extract compressed data from directory entries, to account for weird zipfiles which contain zero-size compressed data on dir entries.
+         Hopefully this fix won't cause any issues on weird zip archives, because it assumes the low 16-bits of zip external attributes are DOS attributes (which I believe they always are in practice).
+- Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the internal attributes, just the filename and external attributes
+- mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed
+- Added cmake support for Linux builds which builds all the examples, tested with clang v3.3 and gcc v4.6.
+- Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti
+- Merged MZ_FORCEINLINE fix from hdeanclark
+- Fix <time.h> include before config #ifdef, thanks emil.brink
+- Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping (super useful for OpenGL apps), and explicit control over the compression level (so you can
+        set it to 1 for real-time compression).
+- Merged in some compiler fixes from paulharris's github repro.
+- Retested this build under Windows (VS 2010, including static analysis), tcc  0.9.26, gcc v4.6 and clang v3.3.
+- Added example6.c, which dumps an image of the mandelbrot set to a PNG file.
+- Modified example2 to help test the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more.
+- In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix possible src file fclose() leak if alignment bytes+local header file write faiiled
+- In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader(): Was pushing the wrong central dir header offset, appears harmless in this release, but it became a problem in the zip64 branch
+
+### v1.14 - May 20, 2012
+
+(SVN Only) Minor tweaks to get miniz.c compiling with the Tiny C Compiler, added #ifndef MINIZ_NO_TIME guards around utime.h includes. Adding mz_free() function, so the caller can free heap blocks returned by miniz using whatever heap functions it has been configured to use, MSVC specific fixes to use "safe" variants of several functions (localtime_s, fopen_s, freopen_s).
+
+MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE, #include <time.h> (thanks fermtect).
+
+Compiler specific fixes, some from fermtect. I upgraded to TDM GCC 4.6.1 and now static __forceinline is giving it fits, so I'm changing all usage of __forceinline to MZ_FORCEINLINE and forcing gcc to use __attribute__((__always_inline__)) (and MSVC to use __forceinline). Also various fixes from fermtect for MinGW32: added #include , 64-bit ftell/fseek fixes.
+
+### v1.13 - May 19, 2012
+
+From jason@cornsyrup.org and kelwert@mtu.edu - Most importantly, fixed mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bits. Temporarily/locally slammed in "typedef unsigned long mz_ulong" and re-ran a randomized regression test on ~500k files. Other stuff:
+
+Eliminated a bunch of warnings when compiling with GCC 32-bit/64. Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze (static analysis) option and fixed all warnings (except for the silly "Use of the comma-operator in a tested expression.." analysis warning, which I purposely use to work around a MSVC compiler warning).
+
+Created 32-bit and 64-bit Codeblocks projects/workspace. Built and tested Linux executables. The codeblocks workspace is compatible with Linux+Win32/x64. Added miniz_tester solution/project, which is a useful little app derived from LZHAM's tester app that I use as part of the regression test. Ran miniz.c and tinfl.c through another series of regression testing on ~500,000 files and archives. Modified example5.c so it purposely disables a bunch of high-level functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the MINIZ_NO_STDIO bug report.)
+
+Fix ftell() usage in a few of the examples so they exit with an error on files which are too large (a limitation of the examples, not miniz itself). Fix fail logic handling in mz_zip_add_mem_to_archive_file_in_place() so it always calls mz_zip_writer_finalize_archive() and mz_zip_writer_end(), even if the file add fails.

+
+### v1.12 - 4/12/12
+
+More comments, added low-level example5.c, fixed a couple minor level_and_flags issues in the archive API's.
+level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce Dawson <bruced@valvesoftware.com> for the feedback/bug report.
+
+### v1.11 - 5/28/11
+
+Added statement from unlicense.org
+
+### v1.10 - 5/27/11
+
+- Substantial compressor optimizations:
+- Level 1 is now ~4x faster than before. The L1 compressor's throughput now varies between 70-110MB/sec. on a Core i7 (actual throughput varies depending on the type of data, and x64 vs. x86).
+- Improved baseline L2-L9 compression perf. Also, greatly improved compression perf. issues on some file types.
+- Refactored the compression code for better readability and maintainability.
+- Added level 10 compression level (L10 has slightly better ratio than level 9, but could have a potentially large drop in throughput on some files).
+
+### v1.09 - 5/15/11
+
+Initial stable release.

+/* miniz.c 3.0.0 - public domain deflate/inflate, zlib-subset, ZIP reading/writing/appending, PNG writing
+   See "unlicense" statement at the end of this file.
+   Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13, 2013
+   Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951: http://www.ietf.org/rfc/rfc1951.txt
+
+   Most API's defined in miniz.c are optional. For example, to disable the archive related functions just define
+   MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros).
+
+   * Low-level Deflate/Inflate implementation notes:
+
+     Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or
+     greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses
+     approximately as well as zlib.
+
+     Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function
+     coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory
+     block large enough to hold the entire file.
+
+     The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation.
+
+   * zlib-style API notes:
+
+     miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in
+     zlib replacement in many apps:
+        The z_stream struct, optional memory allocation callbacks
+        deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
+        inflateInit/inflateInit2/inflate/inflateReset/inflateEnd
+        compress, compress2, compressBound, uncompress
+        CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines.
+        Supports raw deflate streams or standard zlib streams with adler-32 checking.
+
+     Limitations:
+      The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries.
+      I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but
+      there are no guarantees that miniz.c pulls this off perfectly.
+
+   * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by
+     Alex Evans. Supports 1-4 bytes/pixel images.
+
+   * ZIP archive API notes:
+
+     The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to
+     get the job done with minimal fuss. There are simple API's to retrieve file information, read files from
+     existing archives, create new archives, append new files to existing archives, or clone archive data from
+     one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h),
+     or you can specify custom file read/write callbacks.
+
+     - Archive reading: Just call this function to read a single file from a disk archive:
+
+      void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name,
+        size_t *pSize, mz_uint zip_flags);
+
+     For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central
+     directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files.
+
+     - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file:
+
+     int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags);
+
+     The locate operation can optionally check file comments too, which (as one example) can be used to identify
+     multiple versions of the same file in an archive. This function uses a simple linear search through the central
+     directory, so it's not very fast.
+
+     Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and
+     retrieve detailed info on each file by calling mz_zip_reader_file_stat().
+
+     - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data
+     to disk and builds an exact image of the central directory in memory. The central directory image is written
+     all at once at the end of the archive file when the archive is finalized.
+
+     The archive writer can optionally align each file's local header and file data to any power of 2 alignment,
+     which can be useful when the archive will be read from optical media. Also, the writer supports placing
+     arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still
+     readable by any ZIP tool.
+
+     - Archive appending: The simple way to add a single file to an archive is to call this function:
+
+      mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name,
+        const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags);
+
+     The archive will be created if it doesn't already exist, otherwise it'll be appended to.
+     Note the appending is done in-place and is not an atomic operation, so if something goes wrong
+     during the operation it's possible the archive could be left without a central directory (although the local
+     file headers and file data will be fine, so the archive will be recoverable).
+
+     For more complex archive modification scenarios:
+     1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to
+     preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the
+     compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and
+     you're done. This is safe but requires a bunch of temporary disk space or heap memory.
+
+     2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(),
+     append new files as needed, then finalize the archive which will write an updated central directory to the
+     original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a
+     possibility that the archive's central directory could be lost with this method if anything goes wrong, though.
+
+     - ZIP archive support limitations:
+     No spanning support. Extraction functions can only handle unencrypted, stored or deflated files.
+     Requires streams capable of seeking.
+
+   * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the
+     below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it.
+
+   * Important: For best perf. be sure to customize the below macros for your target platform:
+     #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
+     #define MINIZ_LITTLE_ENDIAN 1
+     #define MINIZ_HAS_64BIT_REGISTERS 1
+
+   * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before including miniz.c to ensure miniz
+     uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be able to process large files
+     (i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes).

+## Miniz
+
+Miniz is a lossless, high performance data compression library in a single source file that implements the zlib (RFC 1950) and Deflate (RFC 1951) compressed data format specification standards. It supports the most commonly used functions exported by the zlib library, but is a completely independent implementation so zlib's licensing requirements do not apply. Miniz also contains simple to use functions for writing .PNG format image files and reading/writing/appending .ZIP format archives. Miniz's compression speed has been tuned to be comparable to zlib's, and it also has a specialized real-time compressor function designed to compare well against fastlz/minilzo.
+
+## Usage
+
+Releases are available at the [releases page](https://github.com/richgel999/miniz/releases) as a pair of `miniz.c`/`miniz.h` files which can be simply added to a project. To create this file pair the different source and header files are [amalgamated](https://www.sqlite.org/amalgamation.html) during build. Alternatively use as cmake or meson module (or build system of your choice).
+
+## Features
+
+* MIT licensed
+* A portable, single source and header file library written in plain C. Tested with GCC, clang and Visual Studio.
+* Easily tuned and trimmed down by defines
+* A drop-in replacement for zlib's most used API's (tested in several open source projects that use zlib, such as libpng and libzip).
+* Fills a single threaded performance vs. compression ratio gap between several popular real-time compressors and zlib. For example, at level 1, miniz.c compresses around 5-9% better than minilzo, but is approx. 35% slower. At levels 2-9, miniz.c is designed to compare favorably against zlib's ratio and speed. See the miniz performance comparison page for example timings.
+* Not a block based compressor: miniz.c fully supports stream based processing using a coroutine-style implementation. The zlib-style API functions can be called a single byte at a time if that's all you've got.
+* Easy to use. The low-level compressor (tdefl) and decompressor (tinfl) have simple state structs which can be saved/restored as needed with simple memcpy's. The low-level codec API's don't use the heap in any way.
+* Entire inflater (including optional zlib header parsing and Adler-32 checking) is implemented in a single function as a coroutine, which is separately available in a small (~550 line) source file: miniz_tinfl.c
+* A fairly complete (but totally optional) set of .ZIP archive manipulation and extraction API's. The archive functionality is intended to solve common problems encountered in embedded, mobile, or game development situations. (The archive API's are purposely just powerful enough to write an entire archiver given a bit of additional higher-level logic.)
+
+## Building miniz - Using vcpkg
+
+You can download and install miniz using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
+
+    git clone https://github.com/Microsoft/vcpkg.git
+    cd vcpkg
+    ./bootstrap-vcpkg.sh
+    ./vcpkg integrate install
+    ./vcpkg install miniz
+
+The miniz port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
+
+## Known Problems
+
+* No support for encrypted archives. Not sure how useful this stuff is in practice.
+* Minimal documentation. The assumption is that the user is already familiar with the basic zlib API. I need to write an API wiki - for now I've tried to place key comments before each enum/API, and I've included 6 examples that demonstrate how to use the module's major features.
+
+## Special Thanks
+
+Thanks to Alex Evans for the PNG writer function. Also, thanks to Paul Holden and Thorsten Scheuermann for feedback and testing, Matt Pritchard for all his encouragement, and Sean Barrett's various public domain libraries for inspiration (and encouraging me to write miniz.c in C, which was much more enjoyable and less painful than I thought it would be considering I've been programming in C++ for so long).
+
+Thanks to Bruce Dawson for reporting a problem with the level_and_flags archive API parameter (which is fixed in v1.12) and general feedback, and Janez Zemva for indirectly encouraging me into writing more examples.
+
+## Patents
+
+I was recently asked if miniz avoids patent issues. miniz purposely uses the same core algorithms as the ones used by zlib. The compressor uses vanilla hash chaining as described [here](https://datatracker.ietf.org/doc/html/rfc1951#section-4). Also see the [gzip FAQ](https://web.archive.org/web/20160308045258/http://www.gzip.org/#faq11). In my opinion, if miniz falls prey to a patent attack then zlib/gzip are likely to be at serious risk too.
