          Release Notes: Several fatal bugs in LZX, Quantum, CAB, and CHM decoding have been fixed. Searching for cabinets now works correctly for files over two gigabytes in size. New features include a rewritten, faster MSZIP decoder, a versioned ABI, and a sample mspack_system implementation that can concurrently read/write files in memory, regular disk files, file handles, and file descriptors.
