## :tada: Preview Features
- Extended the Flow Graph receiving nodes with a new ``try_put_and_wait`` API that submits a message to the graph and waits for its completion.

## :rotating_light: Known Limitations
- The ``oneapi::tbb::info`` namespace interfaces might unexpectedly change the process affinity mask on Windows* OS systems (see https://github.com/open-mpi/hwloc/issues/366 for details) when using hwloc version lower than 2.5.

- On Windows OS on ARM64*, when compiling an application using oneTBB with the Microsoft* Compiler, the compiler issues a warning C4324 that a structure was padded due to the alignment specifier. Consider suppressing the warning by specifying /wd4324 to the compiler command line.
- C++ exception handling mechanism on Windows* OS on ARM64* might corrupt memory if an exception is thrown from any oneTBB parallel algorithm (see Windows* OS on ARM64* compiler issue: https://developercommunity.visualstudio.com/t/ARM64-incorrect-stack-unwinding-for-alig/1544293.
- When CPU resource coordination is enabled, tasks from a lower-priority ``task_arena`` might be executed before tasks from a higher-priority ``task_arena``.
- Using oneTBB on WASM*, may cause applications to run in a single thread. See [Limitations of WASM Support](https://github.com/oneapi-src/oneTBB/blob/master/WASM_Support.md#limitations).

> **_NOTE:_** To see known limitations that impact all versions of oneTBB, refer to [oneTBB Documentation](https://oneapi-src.github.io/oneTBB/main/intro/limitations.html).


## :hammer: Fixed Issues
- Fixed ``parallel_for_each`` algorithm behavior for iterators defining ``iterator_concept`` trait instead of ``iterator_category``.
- Fixed the redefinition issue for ``std::min`` and ``std::max`` on Windows* OS ([GitHub* #832](https://github.com/oneapi-src/oneTBB/issues/832)).
- Fixed the incorrect binary search order in ``TBBConfig.cmake``.
- Enabled the oneTBB library search using the pkg-config tool in Conda packages.
## :hammer: Issues Fixed
- Fixed the missed signal for thread request for enqueue operation.
- Significantly improved scalability of ``task_group``, ``flow_graph``, and ``parallel_for_each``.
- Removed usage of ``std::aligned_storage`` deprecated in C++23 (Inspired by Valery Matskevich https://github.com/oneapi-src/oneTBB/pull/1394).
- Fixed the issue where ``oneapi::tbb::info`` interfaces might interfere with the process affinity mask on the Windows* OS systems with multiple processor groups.


## :octocat: Open-source Contributions Integrated
