	* Version 1.4.1

	In 1.4 development cycle, we developed 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

Thu Jul 13 2017 Krzysztof Czurylo <krzysztof.czurylo@intel.com>

	* 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
	remote access to persistent memory and to provide basic data replication
	over RDMA.  The librpmem is still considered experimental.

Tue Feb 21 2017 Krzysztof Czurylo <krzysztof.czurylo@intel.com>

	* 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(3) for details.

	- test: fix match files in pmempool_transform/TEST8

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 (#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 http://pmem.io.
	- Add "sync" and "transform" commands to pmempool utility.
	  The "sync" command allows 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 (#197)
	- obj: add C++ bindings package (libpmemobj++-devel)
	- obj: add TOID_OFFSETOF macro
	- pmempool: add "sync" and "transform" commands (#172, #196)

	Bug fixes:
	- obj: force alignment of pmem lock structures (#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() (#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() (#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 (#158)
	- obj: add TOID_TYPEOF macro

	Bug fixes:
	- doc: update description of valid file size units (#133)
	- pmempool: fix --version short option in man page (#135)
	- pmempool: print usage when running rm without arg (#136)
	- cpp: clarify polymorphism in persistent_ptr (#150)
	- obj: let the before flag be any non-zero value (#151)
	- obj: fix compare array pptr to nullptr (#152)
	- obj: cpp pool.get_root() fix (#156)
	- log/blk: set errno if replica section is specified (#161)
	- cpp: change exception message	(#163)
	- doc: remove duplicated words in man page (#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 http://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.

Thu Sep 11 2014 Andy Rudoff <andy.rudoff@intel.com>

	* Version 0.1
	Initial development done in 0.1 builds
