2009-09-02 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.8 released.
* Compression time has been reduced by 4%.
* Lzdiff and lzgrep have been moved to the new package zutils.
* Fixed warnings on sistems where uint32_t != unsigned int.
2009-06-25 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.7 released.
* decoder.h (copy_block): Fixed memcpy overlap introduced in 1.6.
2009-06-22 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.6 released.
* Decompression time has been reduced by 17%.
* Added decompression support for Sync Flush marker.
* Added support for .tbz extension to lzdiff and lzgrep.
* Added man pages for lzdiff, lzgrep and lziprecover.
* encoder.cc (Matchfinder): Reduce memory use to 9x if input file
is smaller than dictionary size limit.
* decoder.cc: Added extra flush calls to improve partial
decompression of corrupt files.
* "--test" no more needs "/dev/null".
* Removed some "bashisms" from lzdiff and lzgrep.
* Dictionary size for options "-1" to "-4" has been changed.
* main.cc (signal_handler): Declared as `extern "C"'.
* Makefile.in: Extra files are now installed by default.
* testsuite/check.sh: Test lziprecover.
* Added "export LC_ALL=C" to all scripts.
2009-04-12 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.5 released.
* lzip.h: Coded dictionary size implemented in File_header.
* Fixed some includes that prevented compilation with GCC 4.4.
* "member_size" and "volume_size" are now accurate limits.
* Compression speed has been improved.
* Implemented bt4 type matchfinder.
* Added chapter "Algorithm" to the manual.
* Lzdiff and lzgrep now accept "-h" for "--help" and
"-V" for "--version".
* Makefile.in: Man page is now installed by default.
* testsuite/check.sh: Verify that files are open in binary mode.
2009-01-24 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.4 released.
* Implemented compression of version 1 files.
* Added new option "--member-size".
* Added new option "--volume-size".
* Added new option "--output".
* main.cc: Read from non regular files if "--stdout" is specified.
* Added "lziprecover", a member recoverer program.
* testsuite/unzcrash.cc: Test all 1-byte errors.
2008-12-21 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.3 released.
* This version automatically chooses the smallest possible
dictionary size for each file during compression, saving
memory during decompression.
* Implemented decompression of version 1 files.
* testsuite/check.sh: Replaced "diff -q" with "cmp".
2008-12-10 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.2 released.
* encoder.cc: A 1-byte read outside allocated memory has been fixed.
* lzip.h: Dictionary size limit has been reduced to 512MiB because
setting it to 1GiB causes overflow of a 32 bit integer.
* Added "lzdiff", a diff/cmp wrapper for gzip, bzip2, lzip and
non-compressed files.
* Added "lzgrep", a grep wrapper for gzip, bzip2, lzip and
non-compressed files.
