  1. Lizard v1.0
  2. - LZ5 v2.0 was renamed to Lizard v1.0
  3. - improved compression speed with many small files
  4. LZ5 v2.0
  5. - this version is optimized for decompression speed (instead of ratio for previous versions)
  6. - LZ5 v2.0 contains 4 compression methods:
  7. fastLZ4 : compression levels -10...-19 are designed to give better decompression speed than LZ4 i.e. over 2000 MB/s
  8. LIZv1 : compression levels -20...-29 are designed to give better ratio than LZ4 keeping 75% decompression speed
  9. fastLZ4 + Huffman : compression levels -30...-39 add Huffman coding to fastLZ4
  10. LIZv1 + 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
  11. LZ5 v1.5
  12. - introduced compatibility with Visual C++ 2010 and newer
  13. - attached Visual Studio 2010 project
  14. - thoroughly tested with 21 Travis CI and 7 AppVeyor CI tests
  15. - fixed bug with reusing a context in lizard_frame.c (LizardF_compressBegin and Lizard_compress_HC_continue)
  16. - fixed rare bug in match finder (concerns levels 4 - 15)
  17. LZ5 v1.4.1
  18. - fixed bug with a backward match extension (level 11 and 12)
  19. LZ5 v1.4
  20. - improved: levels from 13 to 15 (maximum compression ratio)
  21. - added a new parser: LizardHC_optimal_price_bt
  22. - updated documentation: lizard_Block_format.md and lizard_Frame_format.md
  23. - changed lizard.exe: the "-B" option with block size [1-7] = 64KB, 256KB, 1MB, 4MB, 16MB, 64MB, 256MB (default : 4 = 4MB)
  24. LZ5 v1.3.3
  25. - added: new levels from 11 to 18 (maximum compression ratio)
  26. - added: a new parser: LizardHC_optimal_price
  27. - fixed: buffer-overflow during decompression (thanks to m^2)
  28. LZ5 r132
  29. - improved compression ratio
  30. - added: new parsers: LizardHC_fast, LizardHC_price_fast, LizardHC_lowest_price
  31. - added: a special 1-byte codeword for the last occured offset
  32. - added: support for 3-byte long matches (MINMATCH = 3)
  33. LZ5 r131
  34. The first release based on LZ4 r132 dev
