+TBB 4.0 commercial-aligned release
+
+Changes (w.r.t. TBB 3.0 Update 8 commercial-aligned release):
+
+Improvements:
+- concurrent_priority_queue is now a supported feature. Capacity control methods were removed.
+- Flow graph is now a supported feature of TBB, rather than being a community preview feature.
+- A new memory backend has been implemented in the TBB allocator. It can return small memory blocks to the OS and thus later reuse that memory for large object allocation.
+- Improved partitioning algorithms for parallel_for and parallel_reduce to better handle load imbalance.
+- The convex_hull example has been refactored to produce reproducible performance results.
+- The Major Interface version has changed from 5 to 6. Deprecated interfaces might be removed in future releases.
+
+Community Preview Features:
+- Added Community Preview Feature: serial subset of TBB for modeling a sequential execution of a parallel algorithm. This release introduces serial parallel_for.
+- Added Community Preview Feature: or_node (accepts multiple inputs, forwarding each input separately to successors), split_node (accepts tuples, and forwards each element to a corresponding successor), and multioutput_function_node (accepts one input, and passes the input and a tuple of output ports to the function body to support outputs to multiple successors).
+- Added Community Preview Feature: Scalable Memory Pools (more control on memory source, grouping, collective deallocatation).
+
+------------------------------------------------------------------------
+TBB 3.0 Update 8 commercial-aligned release
+
+Changes (w.r.t. TBB 3.0 Update 7 commercial-aligned release):
+
+- Task priorities has become an official feature of TBB,

+- Added task::set_parent() method.
+- Added concurrent_unordered_set container.
+
+Open-source contributions integrated:
+
+- PowerPC support by Raf Schietekat.
+- Fix of potential task pool overrun and other improvements
+ in the task scheduler by Raf Schietekat.
+- Fix in parallel_for_each to work with std::set in Visual* C++ 2010.

+ compiler on Linux.
+- Inconsistency of exception propagation mode possible when application
+ built with Microsoft* Visual Studio* 2008 or earlier uses TBB built
+ with Microsoft* Visual Studio* 2010.
+- Affinitizing master thread to a subset of available CPUs after TBB
+ scheduler was initialized tied all worker threads to the same CPUs.
+- Method is_stolen_task() always returned 'false' for affinitized tasks.
+- write_once_node and overwrite_node did not immediately send buffered
