Intel Threading Building Blocks - History

History

Version 1.0 was introduced by Intel on August 29, 2006, the year after the introduction of Intel's first dual-core x86 processor, the Pentium D.

Version 1.1 was introduced on April 10, 2007. This version introduced auto_partitioner which offered an automatic alternative to specifying a grain size parameter to estimate the best granularity for particular tasks. This version was added to the Intel C++ Compiler 10.0 with the new Professional Edition later that year on June 5.

Version 2.0 was introduced on July 24, 2007. This version included the release of the source code and the creation of an open source project. The license used for open source is the same as the one previously used by the GNU Compiler Collection C++ standard library, a GPLv2 with a "runtime exception" (because of being template heavy code that usually becomes part of the executable after compilation). TBB is still available in a commercial version (without source code) with support but with no differences in functionality from the open source version.

Version 2.1 was introduced on July 22, 2008. Version 2.1 features included task-to-thread affinity, cancellation support, exception handling, and a portable thread wrapper. Version 2.2 features support for lambda functions in C++0x.

Version 3.0 was introduced on May 4, 2010. It has a number of improvements, see (http://software.intel.com/en-us/blogs/2010/05/04/tbb-30-new-today-version-of-intel-threading-building-blocks/)

Version 4.0 was introduced on September 8, 2011. It has several new features, see (http://threadingbuildingblocks.org/whatsnew.php)

Version 4.1 was introduced on September 5, 2012. It has improvements in TBB memory allocator, full support of parallel_deterministic_reduce template function and other updates, see (http://threadingbuildingblocks.org/uploads/77/188/4.1/CHANGES.txt)
