v2.3.0

• Bug fixes
• Performance improvements (Huffman, ANS, ROLZ, TPAQ, ...)
• Code cleanup (dead code removal, internal package creation, refactoring, ...)
• New CLI options (delete source, skip dot files or links)
• The decompressor now checks decompressed size vs original size
• Headerless mode (via API only)

v2.2.0

• Level 4 was too slow and has been replaced: Level 1 to 3 have been promoted and a new Level 1 with no entropy codec has been added
• Rewritten Huffman codec (30% faster)
• Improved LZ codec (better compression)
• Faster UTF transform (>25% faster)
• Many other performance improvements (ANS, ROLZ, CM, ...)
• Bug fixes

v2.1.0

• Improved LZ codec
• Rewritten EXE codec supports X86 and ARM64
• New UTF codec
• Multi threaded mode is now the default
• Faster Huffman decompression

v2.0.0

• Many performance improvements (all levels)
• Level 4, 5, 6, 7 decompress significantly faster
• Reduced memory usage during compression and decompression
• Improve scalability of parallel tasks with huge blocks

v1.9.0

• Level 1 compresses better
• New level 2 to fill a compression/speed gap
• Level 3 compresses slightly better and faster
• Level 5, 6, 7 decompress faster
• Level 8 uses less memory (a bit weaker and faster)
• Partial decompression available (only some blocks)
• Bitstream format frozen

v1.8.0

• Corner cases fixed and code improvements
• Level 1 compresses a lot better
• New codec for some multimedia files added to levels 2 & 3
• Multi-threading rewritten to parallelize entropy (de)coding
• Level 5 faster & level 6 faster (but a bit weaker)

v1.7.0

• Bug fixes and code improvements
• Small compression gains throughout
• Level 1 compresses better (a bit slower)
• Level 6 has been redefined (faster for text files)
• Better handling of small files

v1.6.0

• Bug fixes & code cleanup
• Decompression speed improvements, especially level 4, 5 and 6 (new inverse BWT)
• Better compression ratio at level 1, 2, 5 and 8.
• New Sorted Ranks Transform
• Improved code quality (refactored test code, improved docs, fixed linter warnings, ...)

v1.5.0

• Two new levels (2 and 8) have been introduced to remove gaps in the compression ratio/time curve.
• Many speed improvements for compression ratios similar to 1.4.
• Better text compression at level 0.
• Inverse BWT is now multi-threaded.
• Reduced memory usage of forward BWT.

v1.4.0

• Bug fixes
• Code reorganization: split into 3 repositories (1 per language): kanzi. kanzi-go, kanzi-cpp.
• Code is now go gettable for easy install.
• New ROLZ based compression level 2
• Compression improved in (ex) levels 1, 3 and 5. Level 5 is also faster
• First stage allows up to 8 functions (instead of 4).
