2 - switched to GPL v2 or any later version.
3 - speed up compression by ~10-15% in common cases
4 by some manual unrolling.
5 - import some compiler tricks from JSON::XS.
6 - tune hash functions depending on ULTRA_FAST or VERY_FAST settings.
7 - for typical binary data (e.g. /bin/bash, memory dumps,
8 canterbury corpus etc.), speed is now comparable to fastlz, but
9 with better compression ratio. with ULTRA_FAST, it's typically
10 3-15% faster than fastlz while still maintaining a similar ratio.
11 (amd64 and core 2 duo, ymmv). thanks a lot for the competition :)
12 - undo inline assembly, it is no longer helpful.
