oneTBB 2021.6.0

oneTBB is happy to introduce 2021.6.0 release!

What's New

✅ 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.

🔨 Fixed Issues

• Memory allocator crash on a system with an incomplete /proc/meminfo (GitHub* #584).
• Incorrect blocking of task stealing (GitHub* #478).
• Hang due to incorrect decrement of a limiter_node (GitHub* #634).
• Memory corruption in some rare cases when passing big messages in a flow graph (GitHub* #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).
• Crash when obtaining a range from empty ordered and unordered containers (GitHub* #641).
• Deadlock in a concurrent_vector resize() that could happen when the new size is less than the previous size (GitHub* #733).

See our Release Notes to learn more about known limitations and new features.
