      Release Notes: A bug introduced in version 1.6 that prevented lzip from decompressing some rare files has been fixed. The integrity checking code catches it, so there is no risk of data loss.

        Release Notes: Decompression time has been reduced by 17%. Decompression support for the "Sync Flush marker" from lzlib has been added. Man pages for lzdiff, lzgrep, and lziprecover have been added to the distribution. Memory use has been reduced to 9x if the input file is smaller than dictionary size limit. Flush calls have been added to decompressor to allow partial recovery of the uncompressed data when decompressing a corrupt file. The dependence of "--test" on the existence of "/dev/null" has been removed. Some "bashisms" have been removed from lzdiff and lzgrep.

                Release Notes: Flush calls have been added to the decompressor to allow partial recovery of uncompressed data when decompressing a corrupt file. Lzdiff, lzgrep, and lziprecover are now installed by default. The dependence of "--test" on the existence of "/dev/null" has been removed.

                  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: Compression speed has been improved for very repetitive files. Lzdiff and lzgrep now accept "-h" for "--help" and "-V" for "--version".
