+
+	* 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]

+	- obj: fix run allocated recalculation
+
+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

+
+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.
+
+	New features:
+	- common: unsafe shutdown detection (SDS)
+	- common: detection and repair of uncorrectable memory errors (bad blocks)
+	- pool: new "feature" subcommand for enabling and disabling detection of
+	  unsafe shutdown and uncorrectable memory errors
+	- common: auto flush detection on Windows (on Linux since 1.4)
+	- pmreorder: new tool for verification of persistent memory algorithms
+	- obj: new on media layout
+	- pmem/obj: new flexible memcpy|memmove|memset API

+	- obj: lazily initialized volatile variables (pmemobj_volatile)
+	  (EXPERIMENTAL)
+	- obj: allocation classes with alignment
+	- obj: new action APIs: pmemobj_defer_free, POBJ_XRESERVE_NEW,
+	  POBJ_XRESERVE_ALLOC

+
+	Optimizations:
+	- obj: major performance improvements for AEP NVDIMMs
+	- obj: better space utilization for small allocations
+	- common: call msync only on one page for deep drain
+
+	Other changes:
+	- cto: removed
+	- 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
+	- pmem: fix inconsistency in pmem_is_pmem
+	- common: fix windows mmap destruction
+	- daxio: fix checking and adjusting length

+
+Thu Aug 16 2018 Marcin Ślusarz <marcin.slusarz@intel.com>
+
+	* Version 1.4.2
+
+	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.
+
+	Bug fixes:
+	- pmem: fix clflush bit position
+	- obj: fix invalid OOMs when zones are fully packed
+	- obj: don't register undo logs twice in memcheck

+
+	* Version 1.3
+	This release introduces some useful features and optimizations
+	in libpmemobj.  Most of them are experimental and controlled by
+	the new pmemobj_ctl APIs.  For details, please check the feature
+	requests identified by the issue numbers listed next to the items below.
+
+	Other important changes are related to performance tuning and
+	stabilization of librpmem library, which is used by libpmemobj to get

+
+	* 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.

+
+Fri Dec 30 2016 Krzysztof Czurylo <krzysztof.czurylo@intel.com>
+
+	* 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.
+
+Thu Dec 15 2016 Krzysztof Czurylo <krzysztof.czurylo@intel.com>
+
+	* 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
+
+Thu Jun 23 2016 Krzysztof Czurylo <krzysztof.czurylo@intel.com>
+
+	* 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.
+
+Fri Dec 04 2015 Krzysztof Czurylo <krzysztof.czurylo@intel.com>
+
+	* Version 0.4
+	This NVML version primarily focuses on improving code quality
+	and reliability.  In addition to a couple of bug fixes,
+	the changes include:
+		- benchmarks for libpmemobj, libpmemblk and libvmem
+		- additional pmemobj tests and examples
+		- pool mapping address randomization
+		- added pmempool "rm" command
+		- eliminated libpmem dependency on libpthread
+		- enabled extra warnings
+		- minor performance improvements
+	Man pages are all complete.
+	This release is considered "Beta quality" by the team, having
+	been thoroughly validated, including significant performance analysis.
+	The pmempool command does not yet support "check" and "repair"
+	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.
