Release Notes: There are no major new features, but rather a large set of memory footprint and performance optimizations and several minor additions, like the quick_erase() method. Empty hash tables no longer use any dynamic memory, which makes them more suitable for a "many tables, many of them empty" use case. Updated documentation lists complexity for all functions, and test collection is half again as large.
Release Notes: This is another bugfix release in 1.6 branch. It fixes several bugs with compilation in the main code (mostly C++11) and the test suite (on certain POSIX systems).
Release Notes: This new release in the 1.6 branch fixes several bugs with compilation (both on some POSIX systems and Visual C++ 2008), as well as custom pointer support which caused crashes with certain versions of Boost.Interprocess.
Release Notes: Compared to the 1.4 stable branch there is much improved custom allocator support, specifically targeted at Boost.Interprocess allocators. Containers can be serialized with Boost.Serialization. MCT can now be configured, tested, and installed with GNU Make in addition to SCons.
Release Notes: Linked and forward hash tables have been given a sort() function which changes element iteration order. MCT can now be configured, tested, and installed with GNU Make in addition to SCons. This is likely the last release before stable 1.6.
Release Notes: MCT now supports the Boost Serialization library (but doesn't depend on its presence). New public type properties like mct::is_set can help with template metaprogramming.
