* Version 1.9 released.
* The option '-l, --list' has been ported from lziprecover.
* Don't allow mixing different operations (-d, -l or -t).
* Compression time of option '-0' has been reduced by 6%.
* Compression time of options -1 to -9 has been reduced by 1%.
* Decompression time has been reduced by 7%.
* main.c: Continue testing if any input file is a terminal.
* main.c: Show trailing data in both hexadecimal and ASCII.
* file_index.c: Improve detection of bad dict and trailing data.
* lzip.h: Unified messages for bad magic, trailing data, etc.
* clzip.texi: Added missing chapters from lzip.texi.
2016-05-13 Antonio Diaz Diaz <antonio@gnu.org>
* Version 1.8 released.
* main.c: Added new option '-a, --trailing-error'.
* main.c (decompress): Print up to 6 bytes of trailing data
when '-vvvv' is specified.
* decoder.c (LZd_verify_trailer): Removed test of final code.
* main.c (main): Delete '--output' file if infd is a terminal.
* main.c (main): Don't use stdin more than once.
* clzip.texi: Added chapter 'Trailing data'.
* configure: Avoid warning on some shells when testing for gcc.
* Makefile.in: Detect the existence of install-info.
* testsuite/check.sh: A POSIX shell is required to run the tests.
* testsuite/check.sh: Don't check error messages.
2015-07-07 Antonio Diaz Diaz <antonio@gnu.org>
* Version 1.7 released.
* Ported fast encoder and option '-0' from lzip.
* Makefile.in: Added new targets 'install*-compress'.
2014-08-28 Antonio Diaz Diaz <antonio@gnu.org>
* Version 1.6 released.
* Compression ratio of option '-9' has been slightly increased.
* main.c (close_and_set_permissions): Behave like 'cp -p'.
* clzip.texinfo: Renamed to clzip.texi.
* License changed to GPL version 2 or later.
2013-09-17 Antonio Diaz Diaz <antonio@gnu.org>
* Version 1.5 released.
* Show progress of compression at verbosity level 2 (-vv).
* main.c (show_header): Don't show header version.
* Ignore option '-n, --threads' for compatibility with plzip.
* configure: Options now accept a separate argument.
2013-02-18 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.4 released.
* Multi-step trials have been implemented.
* Compression ratio has been slightly increased.
* Compression time has been reduced by 10%.
* Decompression time has been reduced by 8%.
* 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.
2012-02-25 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.3 released.
* main.c (close_and_set_permissions): Inability to change output
file attributes has been downgraded from error to warning.
* encoder.c (Mf_init): Return false if out of memory instead of
calling cleanup_and_fail.
* Small change in '--help' output and man page.
* Changed quote characters in messages as advised by GNU Standards.
* configure: 'datadir' renamed to 'datarootdir'.
2011-05-18 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.2 released.
* main.c: Added new option '-F, --recompress'.
* main.c (decompress): Print only one status line for each
multimember file when only one '-v' is specified.
* 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.c: Optimize pair price calculations. This
reduces compression time for large values of '--match-length'
by up to 6%.
2011-01-11 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.1 released.
* Code has been converted to 'C89 + long long' from C99.
* main.c: Fixed warning about fchown return value being ignored.
* decoder.c: '-tvvvv' now shows compression ratio.
* main.c: Match length limit set by options -1 to -8 has been
reduced to extend range of use towards gzip. Lower numbers now
compress less but faster. (-1 now takes 43% less time for only
20% larger compressed size).
* Compression ratio of option '-9' has been slightly increased.
* main.c (open_instream): Don't show the message
" and '--stdout' was not specified" for directories, etc.
