Mon Feb 15 2021 Igor Chorążewicz <igor.chorazewicz@intel.com>

	* Version 1.12

	This release introduces new transaction handler type (flat_transaction)
	which solves https://github.com/pmem/libpmemobj-cpp/issues/516 (more
	information can be found in README).

	It also introduces several improvements and bugfixes for radix_tree as
	well as additional methods for pmem::obj::string_view.

	New features:
	- pmem::obj::flat_transaction
	- extend API for pmem::obj::string_view (relational operators, find,
		substr, copy, compare)

	Bug fixes:
	- make default bytes_view implementation in radix_tree work for
		wide characters
	- fix assign_val function in radix tree which incorrectly handled
		inline_string<CharT> for CharT != char
	- fix use after free in radix_tree::erase method

	Other changes:
	- allow using any iterator which supports operator[], operator-() and
		operator--() in pmem::obj::slice

	* Version 1.11

	This release introduces a new experimental container - persistent
	radix_tree along with inline_string and string_view classes.

	It also introduces a new pointer type: self_relative_ptr with
	std::atomic specialization.

	New features:
	- experimental radix_tree container (single-threaded sorted map)
	- experimental inline_string class (class serves similar purpose to
		pmem::obj::string, but keeps the data within the same allocation
		as inline_string itself)
	- string_view class (support for compilers older than C++17)
	- experimental self_relative_ptr and std::atomic<self_relative_ptr>
		specialization (persistent smart ptr which encapsulates the self
		offsetted pointer and provides member access, dereference and
		array access operators - for some workloads it could be faster
		alternative for persistent_ptr)

	Optimizations:
	- optimizations for concurrent_map with self_relative_ptr

	Other changes:
	- missing constructors for basic_string class
	- conversion operator for basic_string class
	- ported libcxx's sorted map tests
	- lower and lower_eq methods for concurrent_map
	- missing constructor for concurrent_map (comparator as an argument)

Thu May 28 2020 Szymon Romik <szymon.romik@intel.com>

	* Version 1.10

	This release introduces a new experimental container - persistent
	concurrent map (based on concurrent skiplist implementation).

	It also introduces some optimizations for existing containers and minor
	bug fixes.

	New features:
	- concurrent_map container
	- swap() method for basic_string

	Optimizations:
	- optimized clear() and erase() for trivial types in segment_vector
	- optimized move constructor and assignment for basic_string

	Bug Fixes:
	- fixed free_data() in concurrent_hash_map

Fri Jan 31 2020 Szymon Romik <szymon.romik@intel.com>

	* Version 1.9

	This release moves segment_vector out of experimental namespace and
	directory. It means that abovementioned container is guaranteed to have
	stable API and on-media layout.

	It also introduces defragmentation functionality with new defrag class
	in pmem::detail namespace and helper classes (which currently reside in
	"detail" directory): enumerable_thread_specific and volatile_state.

	With this release, we also decreased restart time of concurrent_hash_map
	(with a usage of the enumerable_thread_specific feature).

	New features:
	- new methods for pmem::obj::string (find() and its overloads)
	- defragmentation feature as a separate class in pmem::obj namespace and
	  support for the defragmentation in containers: concurrent_hash_map,
	  vector, string
	- removed template parameters from persistent_ptr_base class (make it
	  type agnostic) and moved to the public API
	- new methods for pmem::obj::concurrent_hash_map (insert_or_assign and
	  its overloads)

	Optimizations:
	- bucket rehashing in concurrent_hash_map moved to transaction
	- faster concurrent_hash_map restart (with "persistent TLS")

	Other changes:
	- added GitHub Actions as an additional CI
	- added documentation and doc snippets with some usage examples
	- added compatibility tests for different libpmemobj-cpp versions

Fri Jan 24 2020 Szymon Romik <szymon.romik@intel.com>

	* Version 1.8.1

	This release fixes minor bugs.

	Notable changes:
	- fix compilation error in concurrent_hash_map
	- fix possible deadlock in erase method in concurrent_hash_map

Thu Oct 03 2019 Szymon Romik <szymon.romik@intel.com>

	* Version 1.8

	This release moves persistent array/vector/string/concurrent_hash_map
	out from experimental namespace and directory. It means that
	abovementioned containers are guaranteed to have stable API and on-media
	layout. They are placed now in include/libpmemobj++/container/ directory
	and pmem::obj namespace.

	This release introduces also a new experimental container - persistent
	segment vector with templated segment policies.

	New features:
	- experimental persistent segment vector container

	Bug fixes:
	- fixed insert method in persistent vector
	- fixed move assignment operator in persistent array

	Other changes:
	- extended error messages in exceptions
	- added examples with simplekv using persistent containers
	- added modifiers methods for persistent string
	- added template locks for concurrent_hash_map
	- added layout versioning for concurrent_hash_map

	Optimizations:
	- concurrent_hash_map insert method implemented with tx
	- optimized snapshotting in persistent vector/string

Wed Jun 26 2019 Szymon Romik <szymon.romik@intel.com>

	* Version 1.7

	This release introduces new experimental container - persistent
	concurrent hashmap and persistent string with limited functionality.

	Experimental features:
	- persistent concurrent hashmap
	- persistent string (constructors and modifiers)

	Bug fixes:
	- add option to force define IS_TRIVIALLY_COPYABLE
	- mark allocation_flag constructor as explicit
	- add missing include to v.hpp

Fri Mar 15 2019 Igor Chorążewicz <igor.chorazewicz@intel.com>

	* Version 1.6

	This release introduces ctl support, allocation flags, snapshot
	method and new experimental persistent container - vector.

	New features:
	- add support for pmemobj_ctl_set/get/exec
	- expose allocation flags in make_persistent(_atomic)
	- transaction: add snapshot method

	Experimental features:
	- persistent vector container

	Other changes:
	- automatically start transaction inside pmem::obj::experimental::array
	  modifier methods (assignment operators, swap and fill)
	- add const methods for pmem::obj::experimental::array
	- add Valgrind instrumentation support
	- remove experimental const_contiguous_iterator
	- add get with arguments method overload for v

	Bug fixes:
	- throw an exception when dropping pmem lock failed
	- fix crash when previous transaction failed to start
	- fix forwarding parameters to constructor in make_persistent_atomic

	Optimizations:
	- decrease number of persistent_ptr dereferences in
	  make_persistent_array

Tue Feb 19 2018 Marcin Ślusarz <marcin.slusarz@intel.com>

	* Version 1.5.1

	This release fixes minor bugs and improves documentation.

	Notable changes:
	- fix v swap, assignment operators and constructors
	- change conversion operator from T() to T&() in v<>
	- fix range_snapshotting initialization in array.hpp.
	- fix range_snapshotting_iterator behaviour for snapshot_size == 0.

Fri Oct 26 2018 Marcin Ślusarz <marcin.slusarz@intel.com>

	* Version 1.5

	This is the first release of libpmemobj-cpp as a separate project.

	It introduces one persistent container - array, which has std::array
	like interface. Currently it is considered experimental and lives
	in experimental namespace.

	We have also cleaned up some function names that, in retrospect, were
	chosen poorly. Functions with old names are still there but are
	deprecated.

	Experimental features:
	- volatile resides on pmem class
	- persistent array container
