1N/A3.4 Tue Sep 2 06:45:00 CEST 2008
1N/A - the fix from 3.3 introduced a compression bug, which is fixed in
1N/A this release (which explains the mysterious prerelease...). thanls
1N/A once more to Clément Calmels.
1N/A
1N/A3.3 Mon Aug 25 03:17:42 CEST 2008
1N/A - lzf_compress could access memory after the given input buffer
1N/A when outputting back references. reported with nice testcase
1N/A by Clément Calmels.
1N/A
1N/A3.2 Fri May 9 18:52:23 CEST 2008
1N/A - include a workaround for failing POSIX and real-world compliance
1N/A on 64 bit windows (microsoft claims to support POSIX, but is far
1N/A from it). (bug found and analysed nicely by John Lilley).
1N/A
1N/A3.1 Fri Nov 30 11:33:04 CET 2007
1N/A - IMPORTANT BUGFIX: a too long final literal run would corrupt data
1N/A in the encoder (this was introduced in 3.0 only, earlier versions
1N/A are safe).
1N/A
1N/A3.0 Tue Nov 13 22:13:09 CET 2007
1N/A - switched to 2-clause bsd with "GPL v2 or any later version" option.
1N/A - speed up compression by ~10-15% in common cases
1N/A by some manual unrolling.
1N/A - import some compiler tricks from JSON::XS, for further speed-ups.
1N/A - tune hash functions depending on ULTRA_FAST or VERY_FAST settings.
1N/A - for typical binary data (e.g. /bin/bash, memory dumps,
1N/A canterbury corpus etc.), speed is now comparable to fastlz, but
1N/A with better compression ratio. with ULTRA_FAST, it's typically
1N/A 3-15% faster than fastlz while still maintaining a similar ratio.
1N/A (amd64 and core 2 duo, ymmv). thanks a lot for the competition :)
1N/A - undo inline assembly in compressor, it is no longer helpful.
1N/A - no changes to the decompressor.
1N/A - use a HLOG of 16 by default now (formerly 15).
1N/A
1N/A2.1 Fri Nov 2 13:34:42 CET 2007
1N/A - switched to a 2-clause bsd license with GPL exception.
1N/A - get rid of memcpy.
1N/A - tentatively use rep movsb on x86 and x86_64 (gcc only) for a
1N/A moderate speed improvement.
1N/A - applied patch by Kein-Hong Man to maske lzf.c compile under
1N/A the crippled mingw32 environment.
1N/A
1N/A2.0 Fri Feb 16 23:11:18 CET 2007
1N/A - replaced lzf demo by industrial-strength lzf utility with behaviour
1N/A similar other compression utilities. Thanks for Stefan Traby for
1N/A rewriting it!
1N/A - fix state arg prototype.
1N/A
1N/A1.7 Wed Sep 27 17:29:15 CEST 2006
1N/A - remove bogus "unlzf" patch.
1N/A note to self: never accept well-meant patches.
1N/A - make lzf more robust in presence of padding bytes or sudden eof.
1N/A
1N/A1.6 Fri Jul 7 17:31:26 CEST 2006
1N/A - the lzf example utility will now uncompress if invoked
1N/A as "unlzf" (patch by Scott Feeney).
1N/A - add CHECK_INPUT option that adds more checks for input
1N/A data validity.
1N/A - help applications that do not pass in the correct length
1N/A (such as php) by returning either EINVAL or E2BIG.
1N/A - default HLOG size is now 15 (cpu caches have increased).
1N/A - documentation fixes.
1N/A
1N/A1.51 Thu Apr 14 22:15:46 CEST 2005
1N/A - incorporated C♯ implementation of both the en- and decoder,
1N/A written by "Oren J. Maurice".
1N/A You can find it in the cs/ subdirectory.
1N/A - make FRST, NEXT IDX overridable if lzf_c.c is directly included
1N/A in the code.
1N/A
1N/A1.5 Tue Mar 8 20:23:23 CET 2005
1N/A - incorporated improvements by Adam D. Moss,
1N/A which includes a new VERY_FAST mode which is
1N/A a bit slower than ULTRA_FAST but much better,
1N/A and enabled it as default.
1N/A
1N/A1.401 Thu Mar 3 18:00:52 CET 2005
1N/A - use cstring in c++, not string.h.
1N/A - change of contact address.
1N/A
1N/A1.4 Wed Dec 15 08:08:49 CET 2004
1N/A - very very slight tuning of the hashing function.
1N/A
1N/A1.3 Thu Mar 25 15:41:17 CET 2004
1N/A - changed license of lzf core code to explicitly allow
1N/A relicensing under the GPLv2.
1N/A - added VPATH support as suggested by Björn Eriksson.
1N/A
1N/A1.2 Mon Dec 29 13:47:28 CET 2003
1N/A - avoid spurious memory accesses after the to-be-compressed
1N/A memory region. originally reported by Michal Zalewski.
1N/A - flip LZF_STACK_ARG meaning (to be correct).
1N/A
1N/A1.1 Tue Dec 23 05:48:32 CET 2003
1N/A - removed #warn directive, it's not worth the hassle.
1N/A - add LZF_STACK_ARG and AVOID_ERRNO configurations
1N/A for embedded systems.
1N/A - make it compile cleanly as c++.
1N/A - some small documentation and code fixes.
1N/A
1N/A1.0 Sun Nov 17 12:37:37 CET 2002
1N/A - slightly better compression ratio, almost unmeasurably
1N/A slower.
1N/A - some documentation fixes.
1N/A
1N/A0.4 Thu Jun 13 14:11:10 CEST 2002
1N/A - typoe fix.
