* [phrase library..[@/libs/any/ Any]:]
* [*Initial support for C++20 Modules]. See the docs for more info.
* [phrase library..[@/libs/atomic/ Atomic]:]
* Added TSAN instrumentation in asm-based x86, AArch32, AArch64 and PPC backends. This silences TSAN false errors for code using Boost.Atomic for thread synchronization.
* Following the announcement in Boost 1.84, removed support for Windows versions older than Windows 10.
* A note to MinGW-w64 users. Since Windows SDK headers on MinGW-w64 define `_WIN32_WINNT` to an older Windows version by default, you may need to define `_WIN32_WINNT=0x0A00` or `BOOST_USE_WINAPI_VERSION=0x0A00` when compiling Boost.Atomic and the code that uses Boost.Atomic.
* Support for Windows CE is deprecated and will be removed in a future release.
* Added support for timed waiting operations.
* Exposed `thread_pause` operation, which can be used as a backoff measure in spin loops. Added support for PowerPC and improved support for AArch64 in `thread_pause`.
* Removed `BOOST_ATOMIC_NO_ATOMIC_FLAG_INIT` macro definition. Since the library now requires C++11, `BOOST_ATOMIC_FLAG_INIT` is always supported.
* Enabled bitwise operations for atomic enumerations. This can be useful when enumerations are used to implement bit masks.
* [phrase library..[@/libs/beast/ Beast]:]
* Fixes
* Conditionally defined `immediate_executor_type` in `async_base`.

* [phrase library..[@/libs/conversion/ Conversion]:]
* Added an ability to use `polymorphic_downcast` and `polymorphic_cast` in constexpr (requires C++20).
* [phrase library..[@/libs/core/ Core]:]
* Fixed `bit_ceil` to return 1 for input 0 as per specification. ([github_pr core 199])
* Added support for `std::format` to `boost::core::string_view`. ([github core 190])
* [phrase library..[@/libs/detail/ Detail]:]
* Operators generated by `BOOST_BITMASK` now use underlying type of the enum to implement bitwise operators. The operators are marked `noexcept` and `constexpr`, when possible.
* The function `bitmask_set` generated by `BOOST_BITMASK` is marked deprecated. In a future release, `BOOST_BITMASK` will stop producing this function. Users are recommended to use double negation (`!!mask`) to test if the value is zero. This affects e.g. enums defined in Boost.Filesystem.
* [phrase library..[@/libs/dll/ DLL]:]
* Fixed compiling and exporting on Cygwin. Many thanks to [@https://github.com/Luohaothu Luohao Wang]
for the PR!

* Added `BOOST_DLL_USE_STD_FS` CMake option to match the preprocessor option. Thanks to
[@https://github.com/yurybura Yury Bura] for the PR!
* [phrase library..[@/libs/filesystem/ Filesystem]:]
* Corrected ASAN warnings about comparing pointers to potentially unrelated objects in `path::append`. ([github filesystem 335])
* [phrase library..[@/libs/hash2/ Hash2]:]
* Added Blake2 algorithm (`blake2s_256`, `blake2b_512`).
* Added XXH3 algorithm (`xxh3_128`).
* [phrase library..[@/libs/iterator/ Iterator]:]
* Fixed `filter_iterator` copy/converting constructor, which could previously produce an invalid iterator. ([github iterator 92])
* Removed usage of `is_trivial` in `iterator_facade` as it is deprecated in C++26. ([github iterator 93])
* `iterator_facade::operator[]` now always returns a proxy rather than conditionally returning a value or a proxy. This allows users to bind a reference to the result of the operator, regardless of whether the value type is trivially-copyable. ([github iterator 61])
* The proxy returned by `iterator_facade::operator[]` now supports forwarding dereferencing operators to the referenced value. This allows `it[n]->foo()` and `(*it[n]).foo()` expressions to compile.
* The proxy returned by `iterator_facade::operator[]` now implementes perfect forwarding in its assignment operator.
* [phrase library..[@/libs/log/ Log]:]
* Added support for `BOOST_LOG_WITHOUT_ASIO` configuration macro, which can be used to remove the dependency on Boost.Asio and disable the related functionality.
* Use locale-independent formatting of the file counter in `text_file_backend` when composing log file names. This fixes failures in the subsequent parsing of the file names in `file_collector::scan_for_files`. ([github_pr log 246])
* Added a new `wrap_filter` utility that simplifies injecting user-defined function objects in filtering expressions. ([github log 195])
* [phrase library..[@/libs/mysql/ MySQL]:]
* The `caching_sha2_password` authentication plugin can now be used without TLS.
