Release Notes: Codification of dictionary size in the file header has been changed. At least lzip 1.4 is needed to decompress files produced by lzip 1.5. A problem that prevented compilation with GCC 4.4 has been fixed. Compression speed has been improved for all files, and has even doubled for dictionary sizes of less than 64KiB. Lzdiff and lzgrep now accept "-h" for "--help" and "-V" for "--version". "--member-size" and "--volume-size" have been made more accurate. The chapter "Algorithm" has been added to the manual.
Release Notes: The new option "--output", which sends output to a file when reading from standard input, allowing the direct creation of multivolume compressed tar archives, has been added. The new options "--member-size" and "--volume-size" have been added. This version is able to read from non-regular files. Support for safe recovery of undamaged members from multi-member files has been added. Lziprecover, a member recoverer program, has been added to the distribution.
Release Notes: This version automatically chooses the smallest possible dictionary size for each file during compression, saving memory during decompression. This version is able to decompress version 1 files that will be produced by lzip 1.4. Version 1 files include the size of the compressed data. This will facilitate safe recovery of undamaged members from multimember files.
Release Notes: A 1-byte read outside allocated memory that could theoretically produce a bad compressed file has been fixed. Dictionary size limit has been reduced to 512MiB because setting it to 1GiB causes overflow of a 32-bit integer. Lzdiff and lzgrep have been added to the distribution. "make install-info" should now work on Debian and OS X.
Release Notes: The short name of the option "--dictionary-size" has been changed to "-s". The short name of the option "--match-length" has been changed to "-m". A couple of build problems on BSD have been fixed. Some user messages have been improved.
Release Notes: Small changes have been made to the documentation and user messages.
Release Notes: The decompression speed has been improved by 1%.
Release Notes: This release regains the compression ratio of version 0.2 with a speed that is a 5% faster. A compilation problem on systems where "size_t" is different from "unsigned int" has been fixed.
Release Notes: This release compresses 15% faster but produces files that are 1% larger. The "--test" option now takes precedence over the "--stdout" option.
Release Notes: Some small efficiency improvements and documentation changes have been made.
