    20090511 development release was posted on our open source site.
    Hi all!

    open-source development release was posted to the http://www.threadingbuildingblocks.org/ open source TBB site. The list of changes:

    - Basic support for MinGW32 development kit.
    - Added tbb::zero_allocator class that initializes memory with zeros.
        It can be used as an adaptor to any STL-compatible allocator class.
    - Added tbb::parallel_for_each template function as alias to parallel_do.
    - Added more overloads for tbb::parallel_for.
    - Added support for exact exception propagation (can only be used with
        compilers that support C++0x std::exception_ptr).
    - tbb::atomic template class can be used with enumerations.
    - mutex, recursive_mutex, spin_mutex, spin_rw_mutex classes extended
        with explicit lock/unlock methods.
    - Fixed size() and grow_to_at_least() methods of tbb::concurrent_vector
        to provide space allocation guarantees. More methods added for
        compatibility with std::vector, including some from C++0x.
    - Preview of a lambda-friendly interface for low-level use of tasks.
    - scalable_msize function added to the scalable allocator (Windows only).
    - Rationalized internal auxiliary functions for spin-waiting and backoff.
    - Several tests undergo decent refactoring.

    Changes affecting backward compatibility:

    - Improvements in concurrent_queue, including limited API changes.
        The previous version is deprecated; its functionality is accessible
        via methods of the new tbb::concurrent_bounded_queue class.
    - grow* and push_back methods of concurrent_vector changed to return
        iterators; old semantics is deprecated.


    welcome,
    Vladimir
