v1.9.1

• mem_streambuf: rearrange code to avoid adding int to nullptr which is UB
• poly_span: disable UB sanitizer for calls to m_poly_func
• added some .natvis files

v1.9.0

• New library: pmr_allocator. A C++17 wrapper of std::pmr::polymorphic_allocator with a C++20 interface
• New library: any. An alternative implementation of C++17's std::any
• Proper iterator support in poly_span and stride_span
• utility: added make_nullptr
• type_traits: added type_identity

v1.8.3

• New library: data_mutex. A template pair of an object and a mutex used to synchronize access to it. It makes it hard to cause bugs by forgetting to lock a mutex associated with an object.
• static_vector: added resize with an initializer
• pod_vector: use some algorithms from <alorithm> which improves code generation with MSVC
• atomic: improvements to the interface of atomic_relaxed_counter
• qalgorithm new algorithms:
  • qall_of wraps std::all_of
  • qany_of wraps std::any_of,
  • qnone_of wraps std::none_of
  • New type identity: and identity function similar to std::identity from C++23

v1.8.2

• flat_map:
  • BUGFIX: proper throwing of exceptions in at. #17
  • added a constructor from Container
  • added constructors form iterator ranges
• static_vector:
  • added shim allocator argument to constructors to be used in template code
  • added missing overloads of erase and insert like the ones in std::vector
• flat_set: added constructors from iterator ranges

v1.8.1

• flat_map:
  • fixed transparent lookups for std::string_view (it wouldn't compile)
  • inherit from Compare to make use of EBO
• flat_set:
  • BUGFIX: fixed construction from range when a custom Compare whose equivalence is not the same as operator== for the type
  • inherit from Compare to make use of EBO

v1.8.0

• New library: atomic. Utility extensions for <atomic>
• New library: atomic_shared_ptr_storage. Atomic load and store for std::shared_ptr
• shared_from: fixed bad semicolon paste remnant
• make_ptr: added make_aliased
• General: updated GitHub actions

v1.7.0

• New library: utility. Several generally unrelated utility functions
• New library: shared_from. Replacement for std::enable_shared_from_this
• qalgorithm: span-compatible pfind functions
• small_vector: more tests and unused var fix
• mem_streambuf: fixed typo in static assertion text
• Dev mode: Enable more warnings for msvc
• General: Added several build failure tests

v1.6.3

• expected:
  • specialization for void and reference values and errors
  • alias template eoptional<T> for expected<T, void>
• flat_map and flat_set: added upper_bound and equal_range
• ufunction: fixed issue which was preventing construction from free functions
• Added alias target itlib::itlib to CMakeLists.txt
• Minor typos, docs, test improvements

v1.6.1

• span: constructor deduction from containers
• Updated tests, based on CPM.cmake and iboB/doctest-util
• Minor comments and doc updates

v1.6.0

• small_vector redesign:
  • Smaller size
  • No more passive dynamic buffer
• pod_vector: inherit from allocator to make use of Empty Base Optimization
