| Lizard v1.0 | |
| - LZ5 v2.0 was renamed to Lizard v1.0 | |
| - improved compression speed with many small files | |
| LZ5 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 | |
| LIZv1 : 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 | |
| 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 | |
| LZ5 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 lizard_frame.c (LizardF_compressBegin and Lizard_compress_HC_continue) | |
| - fixed rare bug in match finder (concerns levels 4 - 15) | |
| LZ5 v1.4.1 | |
| - fixed bug with a backward match extension (level 11 and 12) | |
| LZ5 v1.4 | |
| - improved: levels from 13 to 15 (maximum compression ratio) | |
| - added a new parser: LizardHC_optimal_price_bt | |
| - updated documentation: lizard_Block_format.md and lizard_Frame_format.md | |
| - changed lizard.exe: the "-B" option with block size [1-7] = 64KB, 256KB, 1MB, 4MB, 16MB, 64MB, 256MB (default : 4 = 4MB) | |
| LZ5 v1.3.3 | |
| - added: new levels from 11 to 18 (maximum compression ratio) | |
| - added: a new parser: LizardHC_optimal_price | |
| - fixed: buffer-overflow during decompression (thanks to m^2) | |
| LZ5 r132 | |
| - improved compression ratio | |
| - added: new parsers: LizardHC_fast, LizardHC_price_fast, LizardHC_lowest_price | |
| - added: a special 1-byte codeword for the last occured offset | |
| - added: support for 3-byte long matches (MINMATCH = 3) | |
| LZ5 r131 | |
| The first release based on LZ4 r132 dev |
