Tbb

oneTBB is happy to introduce 2021.6.0 release!

What's New
:white_check_mark: New Features
- Improved support and use of the latest C++ standards for parallel_sort that allows using this algorithm with user-defined and standard library-defined objects with modern semantics.
- The following features are now fully functional: task_arena extensions, collaborative_call_once, adaptive mutexes, heterogeneous overloads for concurrent_hash_map, and task_scheduler_handle.
- Added support for Windows* Server 2022 and Python 3.10.

:hammer: Fixed Issues
- Memory allocator crash on a system with an incomplete /proc/meminfo (GitHub* [584](https://github.com/oneapi-src/oneTBB/issues/584)).
- Incorrect blocking of task stealing (GitHub* [478](https://github.com/oneapi-src/oneTBB/issues/478)).
- Hang due to incorrect decrement of a limiter_node (GitHub* [634](https://github.com/oneapi-src/oneTBB/issues/634)).
- Memory corruption in some rare cases when passing big messages in a flow graph (GitHub* [639](https://github.com/oneapi-src/oneTBB/issues/639)).
- Possible deadlock in a throwable flow graph node with a lightweight policy. The lightweight policy is now ignored for functors that can throw exceptions (GitHub* [420](https://github.com/oneapi-src/oneTBB/issues/420)).
- Crash when obtaining a range from empty ordered and unordered containers (GitHub* [641](https://github.com/oneapi-src/oneTBB/issues/641)).
- Deadlock in a concurrent_vector resize() that could happen when the new size is less than the previous size (GitHub* [733](https://github.com/oneapi-src/oneTBB/issues/733)).
