Release Notes: Fixes -O not working on lrztar. Makes it less likely to run out of RAM when working with STDIO or using -U on huge files. Fixes corrupt archives being generated from incompressible data or very small files. Fixes endianness on various platforms for MD5 calculation to work. Fixes rare corruption when compressing with lzma from STDIN. Fixes all blank data being generated when compressing from STDIN on OS X. Performance micro-optimizations. Fixes corrupt archives being generated when all the same non-zero bytes exist on large files.
Release Notes: A massive code rewrite was done. Compression windows should be limited by available RAM now on 64-bit systems. The compression advantages on large files on 64-bit machines with large RAM are massive. The limit on 32-bit is still 2GB. The file format is no longer compatible with earlier versions of lrzip. Support for decompressing older formats is present, but all new files will be generated in the new format. Minor speedups were done. Decompression should no longer stall at 4GB boundaries for extended periods, making decompression much faster for files larger than 4GB. Many documentation and benchmark updates were made.
Release Notes: Updated to be in sync with lzma SDK 9.07beta. Cleanups and fixes of the configure scripts to use the correct package version name. Massive fixes to the memory management code, fixing many 32-bit overflow errors. The window size limit is now 2GB on both 32-bit and 64-bit, which improves compression further. Flushing of data to disk between compression windows was implemented to minimize disk thrashing of read vs write.
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.
