Release Notes: Major bugfixes to deal with numerous memory issues on 32-bit systems, and improved use of extra memory on 64-bit systems by removing old restrictions on window sizes. Compression capabilities were expanded to make the most of LZMA compression modes with more RAM. A failure to compress larger files with large amounts of RAM on 32-bit systems was fixed. A config file option, numerous minor fixes, documentation updates, and minor requested features were added.

Release Notes: The LZMA SDK was updated to the latest version, 4.57. Multithreading support for LZMA was added, which nearly doubles speed. A gzip compression option was added. An assembler module for CRC computation was added, but this is dependent on the processor. More enhancements were made to the lzo_compresses function to avoid LZMA errors. File cleanup was done. was changed to improve compiling. Code cleanup was done. Documentation with benchmarks was improved and expanded. Major bugs were fixed to work on big RAM machines. A major fix was made to prevent copying all data above 4GB uncompressed.

Release Notes: Numerous updates. lzma hanging on incompressible data has been fixed with improved lzo testing. An output directory option, a greater verbosity option, a decompression progress indicator, and nice support have been added. There are numerous minor fixes.

Release Notes: Blocks to be compressed by lzma are now scanned by lzo in advance to find incompressible data and bypass attempting to compress them. This speeds up substantially attempting to compress incompressible files, and should fix the "lzma getting stuck on an incompressible block" bug. Basic Darwin support was added. Compression mode was stratified for lower levels of lzma compression.

Release Notes: The default lzma compression window was increased to improve default compression of very large files. An option for maximum window and compression settings were added. An option for static build was added. The lzma source tree was trimmed, making the lrzip tarball much smaller. A much more informative README was written.
