2 - fixed hash calculation in C♯ version (Tiago Freitas Leal).
3 - unroll copy for small sizes, use memcpy for larger sizes,
4 greatly speeding up decompression in most cases.
5 - finally disable rep movsb - it's a big loss on modern intel cpus,
6 and only a small win on amd cpus.
7 - improve c++ compatibility of the code.

10 - lzf_compress did sometimes write one octet past the given output
11 buffer (analyzed and nice testcase by Salvatore Sanfilippo).

133.4 Tue Sep 2 06:45:00 CEST 2008
14 - the fix from 3.3 introduced a compression bug, which is fixed in
15 this release (which explains the mysterious prerelease...). Thanks
16 once more to Clément Calmels.

19 - lzf_compress could access memory after the given input buffer
20 when outputting back references. reported with nice testcase
21 by Clément Calmels.

233.2 Fri May 9 18:52:23 CEST 2008
24 - include a workaround for failing POSIX and real-world compliance
25 on 64 bit windows (microsoft claims to support POSIX, but is far
26 from it). (bug found and analysed nicely by John Lilley).

283.1 Fri Nov 30 11:33:04 CET 2007
29 - IMPORTANT BUGFIX: a too long final literal run would corrupt data
30 in the encoder (this was introduced in 3.0 only, earlier versions
31 are safe).

2 - switched to 2-clause bsd with "GPL v2 or any later version" option. 34 - switched to 2-clause bsd with "GPL v2 or any later version" option.

4 by some manual unrolling. 36 by some manual unrolling.
5 - import some compiler tricks from JSON::XS, for further speed-ups. 37 - import some compiler tricks from JSON::XS, for further speed-ups.
42 - default HLOG size is now 15 (cpu caches have increased). 74 - default HLOG size is now 15 (cpu caches have increased).
