+3.4 Tue Sep 2 06:45:00 CEST 2008
+ - the fix from 3.3 introduced a compression bug, which is fixed in
+ this release (which explains the mysterious prerelease...). thanls
+ once more to Clément Calmels.
+
+3.3 Mon Aug 25 03:17:42 CEST 2008
+ - lzf_compress could access memory after the given input buffer
+ when outputting back references. reported with nice testcase
+ by Clément Calmels.
+
+3.2 Fri May 9 18:52:23 CEST 2008
+ - include a workaround for failing POSIX and real-world compliance
+ on 64 bit windows (microsoft claims to support POSIX, but is far
+ from it). (bug found and analysed nicely by John Lilley).
+
+3.1 Fri Nov 30 11:33:04 CET 2007
+ - IMPORTANT BUGFIX: a too long final literal run would corrupt data
+ in the encoder (this was introduced in 3.0 only, earlier versions
+ are safe).
+
+3.0 Tue Nov 13 22:13:09 CET 2007
+ - switched to 2-clause bsd with "GPL v2 or any later version" option.
+ - speed up compression by ~10-15% in common cases
+ by some manual unrolling.
+ - import some compiler tricks from JSON::XS, for further speed-ups.
+ - tune hash functions depending on ULTRA_FAST or VERY_FAST settings.
+ - for typical binary data (e.g. /bin/bash, memory dumps,
+ canterbury corpus etc.), speed is now comparable to fastlz, but
+ with better compression ratio. with ULTRA_FAST, it's typically
+ 3-15% faster than fastlz while still maintaining a similar ratio.
+ (amd64 and core 2 duo, ymmv). thanks a lot for the competition :)
+ - undo inline assembly in compressor, it is no longer helpful.
+ - no changes to the decompressor.
+ - use a HLOG of 16 by default now (formerly 15).
+
+2.1 Fri Nov 2 13:34:42 CET 2007
+ - switched to a 2-clause bsd license with GPL exception.
+ - get rid of memcpy.
+ - tentatively use rep movsb on x86 and x86_64 (gcc only) for a
+ moderate speed improvement.
+ - applied patch by Kein-Hong Man to maske lzf.c compile under
+ the crippled mingw32 environment.
+
+2.0 Fri Feb 16 23:11:18 CET 2007
+ - replaced lzf demo by industrial-strength lzf utility with behaviour
+ similar other compression utilities. Thanks for Stefan Traby for
+ rewriting it!
+ - fix state arg prototype.
+
+1.7 Wed Sep 27 17:29:15 CEST 2006
+ - remove bogus "unlzf" patch.
+ note to self: never accept well-meant patches.
+ - make lzf more robust in presence of padding bytes or sudden eof.
+
+1.6 Fri Jul 7 17:31:26 CEST 2006
+ - the lzf example utility will now uncompress if invoked
+ as "unlzf" (patch by Scott Feeney).
+ - add CHECK_INPUT option that adds more checks for input
+ data validity.
+ - help applications that do not pass in the correct length
+ (such as php) by returning either EINVAL or E2BIG.
+ - default HLOG size is now 15 (cpu caches have increased).
+ - documentation fixes.
+
+1.51 Thu Apr 14 22:15:46 CEST 2005
+ - incorporated C♯ implementation of both the en- and decoder,
+ written by "Oren J. Maurice".
+ You can find it in the cs/ subdirectory.
+ - make FRST, NEXT IDX overridable if lzf_c.c is directly included
+ in the code.
+
+1.5 Tue Mar 8 20:23:23 CET 2005
+ - incorporated improvements by Adam D. Moss,
+ which includes a new VERY_FAST mode which is
+ a bit slower than ULTRA_FAST but much better,
+ and enabled it as default.
+
+1.401 Thu Mar 3 18:00:52 CET 2005
+ - use cstring in c++, not string.h.
+ - change of contact address.
+
+1.4 Wed Dec 15 08:08:49 CET 2004
+ - very very slight tuning of the hashing function.
+
+1.3 Thu Mar 25 15:41:17 CET 2004
+ - changed license of lzf core code to explicitly allow
+ relicensing under the GPLv2.
+ - added VPATH support as suggested by Björn Eriksson.
+
+1.2 Mon Dec 29 13:47:28 CET 2003
+ - avoid spurious memory accesses after the to-be-compressed
+ memory region. originally reported by Michal Zalewski.
+ - flip LZF_STACK_ARG meaning (to be correct).
+
+1.1 Tue Dec 23 05:48:32 CET 2003
+ - removed #warn directive, it's not worth the hassle.
+ - add LZF_STACK_ARG and AVOID_ERRNO configurations
+ for embedded systems.
+ - make it compile cleanly as c++.
+ - some small documentation and code fixes.
+
+1.0 Sun Nov 17 12:37:37 CET 2002
+ - slightly better compression ratio, almost unmeasurably
+ slower.
+ - some documentation fixes.
+
+0.4 Thu Jun 13 14:11:10 CEST 2002
+ - typoe fix.
+ - lzf demo program now properly decompresses small files.
+ - fix another 64 bit issue, found by Laurent Deniel.
+
+0.3 Tue Jan 16 13:21:14 CET 2001
+ - fix silly beginners 32/64 bit mistake.
+
+0.2 Thu Jan 4 05:56:42 CET 2001
+ - now totally independent of autoconfig, for
+ easy inclusion into other programs.
+ - much better fine-tuning, faster and better than 0.1.
+
+0.1 2000
+ - initial release.
