- 0.35g (10-Oct-00)
- bug fixes

- compression and uncompression are somewhat faster (5% I think for regular processors)
- a new filter for text files (phrase replacement) has been implemented
- better detection of multimedia files
- bug fixes
- 0.35e (21-Aug-00)
- compression is 5% faster, uncompression is 20% faster
- the three algorithms have been merged into a single, please use now '-mx' to get the best compression ratio
- memory footprint has been reduced, the new memory usage is :
- 6 times block_size during compression
- 5 times block_size during uncompression
- the range of block size has been enlarged up to 20*256kb=4Mb (-b20)
- a new switch (-mm) enables a new algorithm for image and wav files
- 0.35d (06-Aug-00)
- a lot of functions have been added to the dll to manipulate archives
- you can specify now which files you want to extract
- Linux and Solaris versions have been updated
- 0.35c (27-Jul-00)
- zzip has been turned into a dll, zzlib, so that you can use zzip as a command line software or as a library in your program
- compression/uncompression is slightly faster
- 0.35b (19-Jul-00)
- the compression ratio has improved by about 1%, especially with Win32 exe and text files ; I can now compress the Calgary Corpus within 816,000 bytes and the Canterbury Corpus within 471,000 bytes
- 0.35a (09-Jun-00)
- a major release
- some nice commands have been added : deleting files in an archive, adding files (recursively or not) to an existing/new archive, extracting files with full pathname, listing contents of archive, testing archives (command line options have changed !)
- some bug fixes (as usual ;)
- 0.34f (15-May-00)
- some important bug fixes
- the compression ratio improved by 1% thanks to Szymon Grabowski
- 0.34e (27-Apr-00)
- compression is about 5% faster
- some bug fixes
- 0.34d (14-Apr-00)
- (un)compression is about 10% faster
- the compression ratio improved slightly (0.5%)
- some bugfixes
- options -b256,-b512... have been replaced by -b1,-b2...
- a new compression mode for multimedia files (-mm)
- 0.34c (05-Apr-00)
- uncompression is 10% faster
- the algorithm selection is more efficient and faster
- 0.34b (02-Apr-00)
- Another speed improvement, Zzip **0.34b is 15% faster than **0.34a, but memory usage has increased, so that there is now a new option '-lowmem' which limits memory usage
- 0.34a (27-Mar-00)
- Zzip is now 15% faster
- Zzip uses now 40% less memory, 7x block size instead of 10x
- bugfixes concerning the archive feature and the i/o error handler
- 0.33b (24-Mar-00)
- some various bug fixes
- speed improvements (about 5% faster)
