Changes (w.r.t. Intel TBB 4.3 Update 5):
- Supported zero-copy realloc for objects >1MB under Linux* via
mremap system call.
- C++11 move-aware insert and emplace methods have been added to
concurrent_hash_map container.
- install_name is set to @rpath/<library name> on OS X*.
Preview Features:
- Added template class async_node to the flow graph API. It allows a
flow graph to communicate with an external activity managed by
the user or another runtime.
- Improved speed of flow::graph::reset() clearing graph edges.
rf_extract flag has been renamed rf_clear_edges.
- extract() method of graph nodes now takes no arguments.
Bugs fixed:
- concurrent_unordered_{set,map} behaves correctly for degenerate
hashes.
- Fixed a race condition in the memory allocator that may lead to
excessive memory consumption under high multithreading load.
