General changes =============== - Added a CMake option to assume that all types are bitwise serializable by default: ``HPX_SERIALIZATION_WITH_ALL_TYPES_ARE_BITWISE_SERIALIZABLE``. The default value ``OFF`` corresponds to the old behaviour. - Added a version check for Asio. The minimum Asio version supported by |hpx| is 1.12.0. - Fixed a bug affecting usage of actions, where the internals of |hpx| relied on function addresses being unique. This was fixed by relying on variable addresses being unique instead. - Made ``hpx::util::bind`` more strict in checking the validity of placeholders. - Small performance improvement to spinlocks. - Adapted the following parallel algorithms to C++20: ``inclusive_scan``, ``exclusive_scan``, ``transform_inclusive_scan``, ``transform_exclusive_scan``. Breaking changes ================ - The experimental ``hpx::execution::simdpar`` execution policy (introduced in 1.7.0) was renamed to ``hpx::execution::par_simd`` for consistency with the other parallel policies. Closed issues ============= * :hpx-issue:`5494` - Rename `simdpar` execution policy to `par_simd` * :hpx-issue:`5488` - `hpx::util::bind` doesn't bounds-check placeholders * :hpx-issue:`5486` - Possible V1.7.1 release Closed pull requests ==================== * :hpx-pr:`5500` - Minor bug fix in transform exclusive and inclusive scan tests * :hpx-pr:`5499` - Rename simdpar to par_simd * :hpx-pr:`5489` - Adding bound-checking for bind placeholders * :hpx-pr:`5485` - Add Asio version check * :hpx-pr:`5482` - Change extra archive data to rely on uniqueness of a variable address, not a function address * :hpx-pr:`5448` - More fixes to enable for all types to be assumed to be bitwise copyable * :hpx-pr:`5445` - Improve performance of Spinlocks * :hpx-pr:`5444` - Adapt transform_inclusive_scan to C++ 20 * :hpx-pr:`5440` - Adapt transform_exclusive_scan to C++ 20 * :hpx-pr:`5439` - Adapt inclusive_scan to C++ 20 * :hpx-pr:`5436` - Adapt exclusive_scan to C++20
