v2.0
- this version is optimized for decompression speed (instead of ratio for previous versions)
- LZ5 v2.0 contains 4 compression methods:
  fastLZ4 : compression levels -10...-19 are designed to give better decompression speed than LZ4 i.e. over 2000 MB/s
  LZ5v2 : compression levels -20...-29 are designed to give better ratio than LZ4 keeping 75% decompression speed
  fastLZ4 + Huffman : compression levels -30...-39 add Huffman coding to fastLZ4
  LZ5v2 + Huffman : compression levels -40...-49 give the best ratio (comparable to zlib and low levels of zstd/brotli) at decompression speed of 1000 MB/s

v1.5
- introduced compatibility with Visual C++ 2010 and newer
- attached Visual Studio 2010 project
- thoroughly tested with 21 Travis CI and 7 AppVeyor CI tests
- fixed bug with reusing a context in lz5frame.c (LZ5F_compressBegin and LZ5_compress_HC_continue)
- fixed rare bug in match finder (concerns levels 4 - 15)

v1.4.1
- fixed bug with a backward match extension (level 11 and 12)

v1.4
- improved: levels from 13 to 15 (maximum compression ratio)
- added a new parser: LZ5HC_optimal_price_bt
- updated documentation: lz5_Block_format.md and lz5_Frame_format.md 
- changed lz5.exe: the "-B" option with block size [1-7] = 64KB, 256KB, 1MB, 4MB, 16MB, 64MB, 256MB (default : 4 = 4MB)
 
v1.3.3
- added: new levels from 11 to 18 (maximum compression ratio)
- added: a new parser: LZ5HC_optimal_price
- fixed: buffer-overflow during decompression (thanks to m^2)

r132
- improved compression ratio
- added: new parsers: LZ5HC_fast, LZ5HC_price_fast, LZ5HC_lowest_price
- added: a special 1-byte codeword for the last occured offset
- added: support for 3-byte long matches (MINMATCH = 3)

r131
The first release based on LZ4 r132 dev
