1 | 2.2 |
|
|
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. |
|
|
13 | - no changes to the decompressor. |
|

15 | 2.1 Fri Nov 2 13:34:42 CET 2007 |
|
|
16 | - switched to a 2-clause bsd license with GPL exception. |
|
|
17 | - get rid of memcpy. |
|
|
18 | - tentatively use rep movsb on x86 and x86_64 (gcc only) for a |
|
|
19 | moderate speed improvement. |
|
|
20 | - applied patch by Kein-Hong Man to maske lzf.c compile under |
|
|
21 | the crippled mingw32 environment. |
|
|
22 | |
|
|
23 | 2.0 Fri Feb 16 23:11:18 CET 2007 |
|
|
24 | - replaced lzf demo by industrial-strength lzf utility with behaviour |
|
|
25 | similar other compression utilities. Thanks for Stefan Traby for |
|
|
26 | rewriting it! |
|
|
27 | - fix state arg prototype. |
|
|
28 | |
|
|
29 | 1.7 Wed Sep 27 17:29:15 CEST 2006 |
|
|
30 | - remove bogus "unlzf" patch. |
|
|
31 | note to self: never accept well-meant patches. |
|
|
32 | - make lzf more robust in presence of padding bytes or sudden eof. |
|
|
33 | |
|
|
34 | 1.6 Fri Jul 7 17:31:26 CEST 2006 |
|
|
35 | - the lzf example utility will now uncompress if invoked |
|
|
36 | as "unlzf" (patch by Scott Feeney). |
|
|
37 | - add CHECK_INPUT option that adds more checks for input |
|
|
38 | data validity. |
|
|
39 | - help applications that do not pass in the correct length |
|
|
40 | (such as php) by returning either EINVAL or E2BIG. |
|
|
41 | - default HLOG size is now 15 (cpu caches have increased). |
|
|
42 | - documentation fixes. |
