QuickLZ v1.31

Compression at 167 Mbyte/s. Copyright 2006-2008 Lasse Reinhold


Introduction

QuickLZ is a data compression library in portable standard C which gives light but fast compression and is intended for real time compression. QuickLZ can be used for free under the GPL-1 or GPL-2 license (where anything released into public must be open source) or under a commercial license if such has been acquired. Some properties:

* World's fastest compression speed (level 0) for its class of compression ratio. Really.

* A streaming mode for optimal compression ratio of small packets down to 200 - 300 bytes in size.

* Speed is favoured over backwards compatibility. New algorithms and data formats are taken in use for uncompromised performance.


To test if QuickLZ suits your needs, try the file archiver 'quick.exe' with the -mem flag.


Version 1.30 (Released 14th Aug 2007)

Features: Now supporting four compression levels. Level 0 is using a new algorithm which is compressing both faster and better than version 1.20, but on the cost of decompression speed.
API: Large changes - see the manual.
Backwards compatibility: 1.30 can decompress 1.20 data and 1.20 can decompress level 1, 2 and 3 of version 1.30.
Bugs fixed since previous version: None


Version 1.31 (Released 4th Feb 2008)

Bugfix version: Version 1.30 contains a bug which may corrupt data.
