Change log
The version numbering of QuickLZ is on the form a.bc. The digit c is the revision number which is reserved to indicate bug fix releases such that if a bug is found in version a.bc, then version a.b(c + 1) is released fixing the bug.
The digit b is the minor version number which is incremented at releases introducing new features or speed or compression ratio improvements. Backwards compatibility for data format and API can be lost. In this case, any bugs occurring will be fixed in the old versions.
The digit a is the major version number. Note that when digit a is incremented, a new commercial license must be purchased in order to use the new major version commercially.

Version 1.30 14-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 1.20 15-Mar-2007
Features: Now with streaming
compression for optimal compression ratio of small packets down
to 400-500 bytes in size. Also removed size and time overhead
from the normal qlz_compress() so that it is suitable for
smaller data sources.
API: Added the functions stream_compress() and stream_decompress().
Backwards compatibility: Backwards compatibility is lost. Data compressed with version 1.00 or 1.10
cannot be decompressed with version 1.20 or vice versa.
Bugs fixed since previous version: None.

Version 1.10 26-Nov-2006
Features: Now compatible with
x86, x64, IA64, Alpha, SPARC, MIPS, POWER, ARM and the like. For
x86/x64: Increased average speed of compression by 3 Mbyte/s and
decompression by 19 Mbyte/s on the test machines.
API: Some arguments are now void* instead of char*.
Backwards compatibility: Fully compatible. 1.10 can decompress 1.00 data and
vice versa.
Bugs fixed since previous version: None.
