(1.9.1, 1.8.2, 1.7.1, 1.6.1, 1.5.2).

Libpmemobj-cpp Version 1.9.1

This release fixes minor bugs.

Notable changes:

• concurrent_hash_map: fix free_data()
• concurrent_hash_map: make double to size_t cast explicit in defragment()
• peristent_ptr: add missing offset calculation

Libpmemobj-cpp Version 1.8.2

This release fixes minor bugs.

This is the last patch release for libpmemobj-cpp 1.8 version.
Maintenance of this version is no longer supported.

Notable changes:

• vector: fix referencing empty array
• vector: Fix undefined behaviour on realloc

Libpmemobj-cpp Version 1.7.1

This release fixes minor bugs.

This is the last patch release for libpmemobj-cpp 1.7 version.
Maintenance of this version is no longer supported.

Notable changes:

• Properly install pkg-config file for all configurations
• Fix void_t declaration and API usage for concurrent hashmap test

Libpmemobj-cpp Version 1.13.0

This release introduces new concurrent data structure - MPSC queue and implements limited concurrency support for radix tree.

New features:

• Introduce experimental MPSC queue (pmem::obj::experimental::mpsc_queue)
• Implement support for multi-reader single-writer concurrency in pmem::obj::experimental::radix_tree
• Introduce basic_dram_inline_string which can be kept both on pmem and dram

Bug fixes:

• Fix radix_tree leaf layout to ensure proper key/value alignment

Other changes:

• Switch default CMake's build type from "Debug" to "RelWithDebInfo" it's relevant for a GitHub users (who may e.g. run some benchmarks)
• Add std::initializer_list constructor to pmem::obj::array to mimic aggregate initialization post C++20

Libpmemobj-cpp Version 1.6.1

This release fixes minor bugs.

This is the last patch release for libpmemobj-cpp 1.6 version.
Maintenance of this version is no longer supported.

Notable changes:

• string: fix max_size() return value
• allocation_flag: mark constructor as explicit
• peristent_ptr: change ptr_offset_magic to be properly aligned
• fix few headers' includes

Libpmemobj-cpp Version 1.5.2

This release fixes minor bugs.

This is the last patch release for libpmemobj-cpp 1.5 version.
Maintenance of this version is no longer supported.

Notable changes:

• operator[] for contiguous_iterator takes signed integral instead of unsigned
• throw an exception when pmemobj_mutex_unlock fail
• fix crash when a previous transaction failed to start because of already taken lock.

Libpmemobj-cpp Version 1.12

This release introduces new transaction handler type (flat_transaction) which solves #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 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

Libpmemobj-cpp 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 offseted 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)
