Fast LZMA2 DLL v1.0.1

• Fixed a potential crash on memory allocation failure during structure allocations for multi-threaded decoding.
• Renamed DLL for Windows (the POSIX build targets a different name conforming to POSIX conventions).

Fast LZMA2 DLL v1.0.0

• Breaking changes have been made to the API functions.
• Some of the options have been renamed.
• Optimized the encoder, incorporating some of Igor Pavlov's improvements to 7-Zip 18.05, and some novel ones. The speed increase is
  about 5% - 8%.
• Moved detection of repeats from the single-threaded initialization stage to a later, multi-threaded stage to increase speed.
• Removed two compression levels, reducing the total to 10, and tweaked the parameters.
• Improved calculation of the match buffer size. It can still be changed in the options, but the meaning of the value is different.
• Replaced the callbacks for writing and progress with timeouts and new functions to gain direct access to the dictionary buffer and
  the compressed data buffers.
• Added Igor Pavlov's assembler-optimized decoder.
• Multi-threaded decompression.

Fast LZMA2 DLL v0.9.2 beta

Fixed excess memory allocation when the dictionary size is > 64Mb

Fast LZMA2 DLL v0.9.1 beta

Changes in v0.9.1:

• Fixed a bug in compression of very small files when using a high search depth.
• Added an incompressibility checker which processes high-entropy (e.g. encrypted or
  already compressed) data about twice as fast as before.
