Comparing liblzf/Changes (file contents):
Revision 1.14 by root, Thu Mar 3 17:08:17 2005 UTC vs.
Revision 1.33 by root, Tue Nov 13 10:41:52 2007 UTC

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

132.1 Fri Nov 2 13:34:42 CET 2007
14 - switched to a 2-clause bsd license with GPL exception.
15 - get rid of memcpy.
16 - tentatively use rep movsb on x86 and x86_64 (gcc only) for a
17 moderate speed improvement.
18 - applied patch by Kein-Hong Man to maske lzf.c compile under
19 the crippled mingw32 environment.

212.0 Fri Feb 16 23:11:18 CET 2007
22 - replaced lzf demo by industrial-strength lzf utility with behaviour
23 similar other compression utilities. Thanks for Stefan Traby for
24 rewriting it!
25 - fix state arg prototype.
26
271.7 Wed Sep 27 17:29:15 CEST 2006
28 - remove bogus "unlzf" patch.
29 note to self: never accept well-meant patches.
30 - make lzf more robust in presence of padding bytes or sudden eof.
31
321.6 Fri Jul 7 17:31:26 CEST 2006
33 - the lzf example utility will now uncompress if invoked
34 as "unlzf" (patch by Scott Feeney).
35 - add CHECK_INPUT option that adds more checks for input
36 data validity.
37 - help applications that do not pass in the correct length
38 (such as php) by returning either EINVAL or E2BIG.
39 - default HLOG size is now 15 (cpu caches have increased).
40 - documentation fixes.
41
421.51 Thu Apr 14 22:15:46 CEST 2005
43 - incorporated C♯ implementation of both the en- and decoder,
44 written by "Oren J. Maurice <oymaurice@hazorea.org.il>".
45 You can find it in the cs/ subdirectory.
46 - make FRST, NEXT IDX overridable if lzf_c.c is directly included
47 in the code.
48
491.5 Tue Mar 8 20:23:23 CET 2005
50 - incorporated improvements by Adam D. Moss,
51 which includes a new VERY_FAST mode which is
52 a bit slower than ULTRA_FAST but much better,
53 and enabled it as default.
