a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - the fix from 3.3 introduced a compression bug, which is fixed in
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync this release (which explains the mysterious prerelease...). thanls
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync once more to Clément Calmels.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync3.3 Mon Aug 25 03:17:42 CEST 2008
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - lzf_compress could access memory after the given input buffer
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync when outputting back references. reported with nice testcase
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync by Clément Calmels.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync3.2 Fri May 9 18:52:23 CEST 2008
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - include a workaround for failing POSIX and real-world compliance
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync on 64 bit windows (microsoft claims to support POSIX, but is far
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync from it). (bug found and analysed nicely by John Lilley).
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync3.1 Fri Nov 30 11:33:04 CET 2007
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - IMPORTANT BUGFIX: a too long final literal run would corrupt data
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync in the encoder (this was introduced in 3.0 only, earlier versions
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync3.0 Tue Nov 13 22:13:09 CET 2007
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - switched to 2-clause bsd with "GPL v2 or any later version" option.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - speed up compression by ~10-15% in common cases
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync by some manual unrolling.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - import some compiler tricks from JSON::XS, for further speed-ups.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - tune hash functions depending on ULTRA_FAST or VERY_FAST settings.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - for typical binary data (e.g. /bin/bash, memory dumps,
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync canterbury corpus etc.), speed is now comparable to fastlz, but
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync with better compression ratio. with ULTRA_FAST, it's typically
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync 3-15% faster than fastlz while still maintaining a similar ratio.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync (amd64 and core 2 duo, ymmv). thanks a lot for the competition :)
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - undo inline assembly in compressor, it is no longer helpful.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - no changes to the decompressor.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - use a HLOG of 16 by default now (formerly 15).
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync2.1 Fri Nov 2 13:34:42 CET 2007
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - switched to a 2-clause bsd license with GPL exception.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - get rid of memcpy.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - tentatively use rep movsb on x86 and x86_64 (gcc only) for a
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync moderate speed improvement.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - applied patch by Kein-Hong Man to maske lzf.c compile under
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync the crippled mingw32 environment.
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync2.0 Fri Feb 16 23:11:18 CET 2007
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - replaced lzf demo by industrial-strength lzf utility with behaviour
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync similar other compression utilities. Thanks for Stefan Traby for
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync rewriting it!
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - fix state arg prototype.

a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - the lzf example utility will now uncompress if invoked
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync as "unlzf" (patch by Scott Feeney).
a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync - add CHECK_INPUT option that adds more checks for input

a260560bdbc7bd737d59547882cd5e8d77b80d0avboxsync which includes a new VERY_FAST mode which is
