Bibliotekat e kompresimit LZHAM dhe Crunch janë kaluar në domenin publik

Rich Geldreich translated libraries he developed for compression LZHAM dhe Crunch to the public domain (Public Domain), meaning he has completely waived all proprietary rights and provided the opportunity for distribution and use in any form by anyone without restrictions. For jurisdictions where the public domain category is not recognized, appropriate reservations have been made. Previously, projects were distributed under the MIT and ZLIB licenses. The Crunch library provides means for compressing and transcoding textures without loss of quality using algorithms

DXTn . Crunch supports texture formats DXT1/5/N and 3DC, and can save the results in DDS, CRN, and KTX formats.LZHAM provides a compression algorithm optimized for packaging resources included in game applications. An API compatible with Zlib is supported. Features of LZHAM include

the use of lookup tables (up to 64 KB), dictionaries (up to 500 MB), parallel operations across multiple threads, and the application of delta changes, allowing changes to be distributed without repacking already compressed files.
In terms of compression level and packaging speed, the LZHAM implementation is comparable to LZMA, but in terms of unpacking speed, it outperforms LZMA by 1.5-8 times (though it is slower than zlib). When compared to ZSTD, LZHAM surpasses this algorithm in compression efficiency but falls behind in encoding speed by almost an order of magnitude and slightly lags in decoding speed.
