Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses more than bzip2, which makes it well suited for software distribution and data archiving. Lzip is a clean implementation of the LZMA algorithm. The Lzip file format is designed for long-term data archiving. It is clean, provides very safe four factor integrity checking, and is backed by the recovery capabilities of lziprecover.
Release Notes: The compression ratio of option "-9" has been slightly increased. The compression time of option "-0" has been reduced by 2%. "lzip -0" is now comparable in compression speed and ratio to "gzip -6".
Release Notes: Copying of file dates, permissions, and ownership now behaves like "cp -p". (If the user ID or the group ID can't be duplicated, the file permission bits S_ISUID and S_ISGID are cleared). Compression time has been reduced by 4%. Some minor improvements have been made. "lzip.texinfo" has been renamed "lzip.texi".
Release Notes: This release shows the progress of compression at verbosity level 2 (-vv). Decompressing and testing no longer show file version. The option "-n, --threads" is now accepted and ignored for compatibility with plzip. The configure script now accepts options with a separate argument. The chapter "Stream format" and the appendix "Reference source code" have been added to the manual.
Release Notes: Decompressing and testing no longer shows the file version. The "Reference source code" appendix of the manual has been updated to version 0.4 of lzd. Minor fixes have been made.
