+
+ * Version 1.10
+
+ This release introduces a new stable PMDK library, libpmem2, which
+ is the next major release of libpmem.
+ This library has an entirely new, but familiar, API that addresses many
+ shortcomings of the previous version, while retaining all of its
+ functionality. To learn more, see https://pmem.io/pmdk/libpmem2/ or
+ libpmem2(7).
+ The old library, libpmem, is still going to be maintained for the
+ foreseeable future, but we'd like to encourage any new applications to
+ leverage libpmem2.

+Fri Jul 3 2020 Piotr Balcer <piotr.balcer@intel.com>
+
+ * Version 1.9
+
+ This release:
+ - Switches the default instruction set for memcpy, memmove and memset
+ implementations on x86 to AVX512, and introduces numerous performance
+ improvements for those operations on AVX and SSE2 fallback paths.
+ - Optimizes transactional allocations in libpmemobj by avoiding one
+ extraneous cache miss and reducing the amount of work required to perform
+ a reservation.
+ - Introduces a new API in libpmemobj, pmemobj_tx_set_failure_behavior,
+ that enables the application to control the behavior of aborting
+ transactions.
+ - Improves performance of pool creation on Windows by avoiding expensive
+ physical page allocation during file allocation.
+ - Stabilizes support for ppc64.
+
+ Other changes:
+ - pmem: mem[cpy|set] optimization when eADR is available
+ - obj: detect msync failures in non-pmem variants of mem[cpy|move|set]
+
+ Notable bug fixes:
+ - core: fix Last_errormsg_get when NO_LIBPTHREAD is defined
+ - pmem: read Unsafe Shutdown Count from region instead of interleave set
+ - common: fix deep_flushes failing on platforms that don't need them

+
+Fri Jan 31 2020 Marcin Ślusarz <marcin.slusarz@intel.com>
+
+ * Version 1.8
+
+ This release:
+ - Introduces new API in libpmemobj for user-assisted defragmentation
+ (see pmemobj_defrag man page for details).
+ - Introduces experimental support for PPC64LE architecture.
+ - Introduces new flag in libpmemobj for opting-out of transaction aborts
+ on failure (POBJ_TX_NO_ABORT), along with new variants of existing APIs
+ that didn't accept flags (pmemobj_tx_xfree, pmemobj_tx_xpublish,
+ pmemobj_tx_xlock, pmemobj_tx_xlog_append_buffer, pmemobj_tx_xstrdup,
+ pmemobj_tx_xwcsdup).
+ - Moves out libvmem and libvmmalloc to the new repository
+ (https://github.com/pmem/vmem).
+
+ Other changes:
+ - obj: introduce new statistics useful for defrag
+ - obj: introduce transient/persistent statistics enabling
+ - obj: introduce pmemobj_tx_(set/get)_user_data funcs
+ - obj: introduce pmemobj_(set/get)_user_data funcs

+
+Mon Sep 30 2019 Marcin Ślusarz <marcin.slusarz@intel.com>
+
+ * Version 1.7
+
+ This release:
+ - Introduces new APIs in libpmemobj for managing space used by transactions.
+ (see pmemobj_tx_log_append_buffer man page for details)
+ - Introduces new APIs in librpmem, splitting rpmem_persist into rpmem_flush
+ and rpmem_drain, allowing applications to use the flush + drain model
+ already known from libpmem. (libpmemobj does not use this feature yet)
+ - Optimizes large libpmemobj transactions by significantly reducing
+ the amount of memory modified at the commit phase.
+ - Optimizes tracking of libpmemobj reservations.
+ - Adds new flags for libpmemobj's pmemobj_tx_xadd_range[_direct] API:
+ POBJ_XADD_NO_SNAPSHOT and POBJ_XADD_ASSUME_INITIALIZED, allowing
+ applications to optimize how memory is tracked by the library.
+
+ To support some of the above changes the libpmemobj on-media layout had
+ to be changed, which means that old pools have to be converted using
+ pmdk-convert >= 1.7.
+
+ Other changes:
+ - obj: fix merging of ranges when NOFLUSH flag is used (pmem/issues#1100)
+ - rpmem: fix closing of ssh connection (pmem/issues#995, pmem/issues#1060)
+ - obj: abort transaction on pmemobj_tx_publish failure
+
+ Internal changes:
+ - test: fault injection tests for pmemblk, pmemlog, and pmemobj
+ - test: improved Python testing framework
+ - test: support real pmem in bad blocks tests
+ - common: allow not building examples and benchmarks

+ Bug fixes:
+ - common: fix device dax detection (compatibility with newer kernels)
+
+Tue Mar 26 2019 Marcin Ślusarz <marcin.slusarz@intel.com>
+
+ * Version 1.6
+
+ This release:
+ - Enables unsafe shutdown and bad block detection on Linux
+ on systems with libndctl >= 63. It is expected that systems with
+ libndctl >= 63 has necessary kernel support (Linux >= 4.20).
+ However, due to bugs in libndctl = 63 and Linux = 4.20, it is
+ recommended to use libndctl >= 64.1 and Linux >= 5.0.4.
+ On systems with libndctl < 63, PMDK uses old superuser-only
+ interfaces. Support for old or new interfaces is chosen at BUILD
+ time.
+ - Introduces arena control interface in pmemobj, allowing applications
+ to tweak performance and scalability of heap operations. See
+ pmemobj_ctl_get man page ("heap" namespace) for details.
+ - Introduces copy_on_write mode, which allows testing applications
+ using pmemobj with pmreorder. See pmemobj_ctl_get man page
+ ("copy_on_write" namespace) for details.
+
+ Other changes:
+ - allocate file space when creating a pool on existing file
+ (pmem/issues#167)
+ - initial support for testing using fault injection
+ - initial Python test framework
+ - improve performance of pmemobj_pool_by_ptr
+
+ Bug fixes:
+ - common: work around tmpfs bug during pool creation
+ (pmem/issues#1018)
+ - pool: race-free pmempool create --max-size
+ - obj: don't modify remote pools in pmemobj_check
+
+Tue Feb 19 2019 Marcin Ślusarz <marcin.slusarz@intel.com>
+
+ * Version 1.5.1
+
+ This release fixes minor bugs and improves compatibility with newer
+ tool chains.
+
+ Notable bug fixes:
+ - common: make detection of device-dax instances more robust
+ - obj: fix pmemobj_check for pools with some sizes
+ - obj: don't use anon struct in an union (public header)
+ - obj: fix pmemobj_tx_lock error handling
+ - obj: don't use braces in an expression with clang (public header)
+ - obj: suppress pmemcheck warnings for statistics
+ - pmreorder: fix markers nontype issue
+
+Fri Oct 26 2018 Marcin Ślusarz <marcin.slusarz@intel.com>
+
+ * Version 1.5
+
+ This release has had two major focus areas - performance and RAS
+ (Reliability, Availability and Serviceability). Beyond that, it introduces
+ new APIs, new tools and many other improvements. As a side effect
+ of performance optimizations, the libpmemobj on-media layout had to be
+ changed, which means that old pools have to be converted using pmdk-convert.
+ libpmemcto experiment has been finished and removed from the tree.
+
+ For more details, please see https://pmem.io/2018/10/22/release-1-5.html.

+
+ Optimizations:
+ - obj: major performance improvements for AEP NVDIMMs

+ - obj: remove actions limit
+ - common: new dependency on libndctl on Linux
+ - pmempool: "convert" subcommand is now a wrapper around pmdk-convert
+ (please see https://github.com/pmem/pmdk-convert)
+ - obj: C++ bindings have been moved to a new repository
+ (please see https://github.com/pmem/libpmemobj-cpp)
+
+ Bug fixes:
+ - obj: fix type numbers for pmemobj_list_insert_new

+
+ This release fixes the way PMDK reports its version via
+ pkg-config files.
+
+ Bug fixes:
+ - common: fix reported version
+ - doc: use single "-" in NAME section (pmem/issues#914)
+
+Fri Jun 29 2018 Marcin Ślusarz <marcin.slusarz@intel.com>
+
+ * Version 1.4.1
+
+ In 1.4 development cycle, we created new daxio utility
+ (command line tool for performing I/O on Device-DAX), but due
+ to some complications we had to disable it just before
+ the 1.4 release.
+ In 1.4.1 we finally enable it. Daxio depends on ndctl v60.1.
+

+ - pmem: fix clflush bit position
+ - obj: fix invalid OOMs when zones are fully packed
+ - obj: don't register undo logs twice in memcheck

+
+ * Version 1.2.1
+ This NVML release changes the behavior of pmem_is_pmem() on Linux.
+ The pmem_is_pmem() function will now return true only if the entire
+ range is mapped directly from Device DAX (/dev/daxX.Y) without an
+ intervening file system, and only if the corresponding file mapping
+ was created with pmem_map_file(). See libpmem(7) for details.

+
+ * Version 1.2 - Windows Technical Preview #1
+ This is the first Technical Preview release of NVML for Windows.
+ It is based on NVML 1.2 version, but not all the 1.2 features
+ are ported to Windows. In particular, Device DAX and remote access
+ to persistent memory (librpmem) are not supported by design.
+
+ NOTE: This release has not gone through the full validation cycle,
+ but only through some basic tests on Travis and AppVeyor.
+ Thus, it cannot be assumed "Production quality" and should not
+ be used in production environments.
+
+ Besides several minor improvements and bug fixes, all the other
+ changes since NVML 1.2 release were related to Windows support:
+ - win: port libvmem (and jemalloc)
+ - win: benchmarks Windows port
+ - win: fix mapping files of unaligned length
+ - win: clean up possible race condition in mmap_init()
+ - win: enable QueryVirtualMemoryInformation() in pmem_is_pmem()
+ - test: check open handles at START/DONE
+ - test: port all the remaining unit tests
+ (scope, pmem_map, obj_debug, util_poolset, pmempool_*)
+ - win: add resource files for versioning
+
+ Known issues and limitations of Windows version of NVML:
+ - Unicode support is missing. The UTF/USC-encoded file paths
+ or pool set files may not be handled correctly.
+ - The libvmmalloc library is not ported yet.
+ - The on-media format of pmem pools is not portable at the moment.
+ The pmem pools created using Windows version of NVM libraries
+ cannot be open on Linux and vice versa.
+ - Despite the fact the current version of NVML would work
+ with any recent version of Windows OS, to take full
+ advantage of PMEM and NVML features and to benefit from
+ the PMEM performance, the recommended platforms needs be
+ equipped with the real NVDIMMs hardware and should support
+ the native, Microsoft's implementation of DAX-enabled file
+ system (i.e. Windows Server 2016 or later).
+ In case of using NVML with older versions of Windows or with
+ the custom implementation of PMEM/DAX drivers, the performance
+ might not be satisfactory. Please, contact the provider
+ of PMEM/DAX drivers for your platform to get the customized
+ version of NVML in such case.

+
+ * Version 1.2
+ This NVML release causes a "flag day" for libpmemobj.
+ The pmemobj pools built under NVML 1.1 are incompatible with pools built
+ under NVML 1.2 and later. This is because an issue was discovered with
+ the alignment of locks (pmem/issues#358) and, although rare, the issue potentially
+ impacts program correctness, making the fix mandatory.
+ The major version number of the pmemobj pool layout and the version
+ of the libpmemobj API is changed to prevent the use of the potentially
+ incorrect layout.
+
+ Other key changes introduced in this release:
+ - Add Device DAX support, providing that "optimized flush" mechanism
+ defined in SNIA NVM Programming Model can safely be used, even
+ if PMEM-aware file system supporting that model is not available,
+ or if the user does not want to use the file system for some reason.
+ - Add a package for libpmemobj C++ bindings.
+ C++ API is no longer considered experimental.
+ Web-based documentation for C++ API is available on https://pmem.io.
+ - Add "sync" and "transform" commands to pmempool utility.
+ The "sync" command allows one to recover missing or corrupted part(s)
+ of a pool set from a healthy replica, while the "transform" command
+ is a convenient way for modifying the structure of an existing
+ pool set, i.e. by adding or removing replicas.
+ - Add experimental support for remote access to persistent memory and
+ basic remote data replication over RDMA (librpmem). Experimental
+ support for remote replicas is also provided by libpmemobj library.
+
+ New features:
+ - common: add Device DAX support (pmem/issues#197)
+ - obj: add C++ bindings package (libpmemobj++-devel)
+ - obj: add TOID_OFFSETOF macro
+ - pmempool: add "sync" and "transform" commands
+ (pmem/issues#172, pmem/issues#196)
+
+ Bug fixes:
+ - obj: force alignment of pmem lock structures (pmem/issues#358)
+ - blk: cast translation entry to uint64_t when calculating data offset
+ - obj: fix Valgrind instrumentation of chunk headers and cancelled
+ allocations
+ - obj: set error message when user called pmemobj_tx_abort()
+ - obj: fix status returned by pmemobj_list_insert() (pmem/issues#226)
+ - obj: defer allocation of global structures
+
+ Optimizations:
+ - obj: fast path for pmemobj_pool_by_ptr() when inside a transaction
+ - obj: simplify and optimize allocation class generation
+
+ Experimental features:
+ - rpmem: add support for remote access to persistent memory and basic
+ remote data replication over RDMA
+ - libpmempool: add pmempool_sync() and pmempool_transform() (pmem/issues#196)
+ - obj: introduce pmemobj_oid()
+ - obj: add pmemobj_tx_xalloc()/pmemobj_tx_xadd_range() APIs and
+ the corresponding macros
+ - obj: add transaction stage transition callbacks

+
+ * Version 1.1
+ This NVML release introduces a new version of libpmemobj pool layout.
+ Internal undo log structure has been modified to improve performance
+ of pmemobj transactions. Memory pools created with older versions
+ of the libpmemobj library must be converted to the new format using
+ "pmempool convert" command. See pmempool-convert(1) for details.
+
+ A new "libpmempool" library is available, providing support for
+ off-line pool management and diagnostics. Initially it provides only
+ "check" and "repair" operations for log and blk memory pools, and for
+ BTT devices.
+
+ Other changes:
+ - pmem: deprecate PCOMMIT
+ - blk: match BTT Flog initialization with Linux NVDIMM BTT
+ - pmem: defer pmem_is_pmem() initialization (pmem/issues#158)
+ - obj: add TOID_TYPEOF macro
+
+ Bug fixes:
+ - doc: update description of valid file size units (pmem/issues#133)
+ - pmempool: fix --version short option in man page (pmem/issues#135)
+ - pmempool: print usage when running rm without arg (pmem/issues#136)
+ - cpp: clarify polymorphism in persistent_ptr (pmem/issues#150)
+ - obj: let the before flag be any non-zero value (pmem/issues#151)
+ - obj: fix compare array pptr to nullptr (pmem/issues#152)
+ - obj: cpp pool.get_root() fix (pmem/issues#156)
+ - log/blk: set errno if replica section is specified (pmem/issues#161)
+ - cpp: change exception message (pmem/issues#163)
+ - doc: remove duplicated words in man page (pmem/issues#164)
+ - common: always append EXTRA_CFLAGS after our CFLAGS
+
+ Experimental features:
+ - Implementation of C++ bindings for libpmempobj is complete.
+ Web-based documentation for C++ API is available on https://pmem.io.
+ Note that C++ API is still considered experimental. Do not use it
+ in production environments.
+ - Porting NVML to Windows is in progress. There are MS Visual Studio
+ solution/projects available, allowing to compile libpmem, libpmemlog,
+ libpmemblk and libpmemobj on Windows, but the libraries are not fully
+ functional and most of the test are not enabled yet.
+
+Thu Apr 07 2016 Krzysztof Czurylo <krzysztof.czurylo@intel.com>
+
+ * Version 1.0
+ The API of six libraries (libpmem, libpmemblk, libpmemlog,
+ libpmemobj, libvmem, libvmmalloc) is complete and stable.
+ The on-media layout of persistent memory pools will be maintained
+ from this point, and if changed it will be backward compatible.
+ Man pages are all complete.
+ This release has been validated to "Production quality".
+
+ For the purpose of new features planned for next releases of NVML
+ there have been some API modifications made:
+ - pmem: pmem_map replaced with pmem_map_file
+ - log/blk: 'off_t' substituted with 'long long'
+ - obj: type numbers extended to 64-bit
+ - obj: new entry points and macros added:
+ pmemobj_tx_errno, pmemobj_tx_lock, pmemobj_mutex_timedlock,
+ TX_ADD_DIRECT, TX_ADD_FIELD_DIRECT, TX_SET_DIRECT
+
+ Other key changes since version 0.4 include:
+ - common: updated/fixed installation scripts
+ - common: eliminated dependency on libuuid
+ - pmem: CPU features/ISA detection using CPUID
+ - obj: improved error handling
+ - obj: atomic allocation fails if constructor returns error
+ - obj: multiple performance optimizations
+ - obj: object store refactoring
+ - obj: additional examples and benchmarks
+
+ This release also introduces a prototype implementation
+ of C++ bindings for libpmemobj. Note that C++ API is still
+ experimental and should not be used in production environments.

+ operations for pmemobj type pools.
+
+Sun Sep 13 2015 Andy Rudoff <andy.rudoff@intel.com>
+
+ * Version 0.3
+ NVML is now feature complete, adding support for:
+ - pool sets
+ - pmemobj local replication (active/passive)
+ - experimental valgrind support
+ - pmempool support for all pool types
+ Man pages are all complete.
+ This release is considered "Alpha quality" by the team, having
+ gone through significant validation but only some performance
+ analysis at this point.
+
+Tue Jun 30 2015 Andy Rudoff <andy.rudoff@intel.com>
+
+ * Version 0.2
+ NVML now consists of six libraries:
+ - libpmem (basic flushing, etc)
+ - libpmemblk, libpmemlog, libpmemobj (transactions)
+ - libvmem, libvmmalloc (volatile use of pmem)
+ The "pmempool" command is available for managing pmem files.
+ Man pages for all the above are complete.
+ The only things documented in man pages but not implemented are:
+ - pmem sets (ability to spread a pool over a set of files)
+ - replication (coming for libpmemobj)
+ The pmempool command does not yet support pmemobj type pools.
