2015-07-08 Antonio Diaz Diaz <antonio@gnu.org>
* Version 1.7 released.
* Ported fast encoder and option '-0' from lzip.
* If open-->write-->finish, produce same dictionary size as lzip.
* Makefile.in: Added new targets 'install*-compress'.
2014-08-27 Antonio Diaz Diaz <antonio@gnu.org>
* Version 1.6 released.
* Compression ratio of option '-9' has been slightly increased.

* License changed to "GPL version 2 or later with link exception".
2013-09-15 Antonio Diaz Diaz <antonio@gnu.org>
* Version 1.5 released.
* Removed decompression support for version 0 files.
* The LZ_compress_sync_flush mechanism has been fixed (again).
* Minor fixes.
2013-05-28 Antonio Diaz Diaz <antonio@gnu.org>
* Version 1.4 released.
* Multi-step trials have been implemented.
* Compression ratio has been slightly increased.
* Compression time has been reduced by 8%.
* Decompression time has been reduced by 7%.
* lzlib.h: Changed 'long long' values to 'unsigned long long'.
* encoder.c (Mf_init): Reduce minimum buffer size to 64KiB.
* lzlib.c (LZ_decompress_read): Tell LZ_header_error from
LZ_unexpected_eof the same way as lzip does.
* Makefile.in: Added new target 'install-as-lzip'.
* Makefile.in: Added new target 'install-bin'.
* main.c: Use 'setmode' instead of '_setmode' on Windows and OS/2.
* main.c: Define 'strtoull' to 'strtoul' on Windows.
2012-02-29 Antonio Diaz Diaz <ant_diaz@teleline.es>

2011-10-25 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.2 released.
* encoder.h (Lee_update_prices): Update high length symbol prices
independently of the value of 'pos_state'. This gives better
compression for large values of '--match-length' without being
slower.
* encoder.h encoder.cc: Optimize pair price calculations. This
reduces compression time for large values of '--match-length'
by up to 6%.
* main.cc: Added new option '-F, --recompress'.
