Show dictionary size at verbosity level 4 (-vvvv). * lzip.texi: Added chapter 'Output'. 2017-04-13 Antonio Diaz Diaz * 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. * lzip_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 * Version 1.8 released. * 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. * check.sh: A POSIX shell is required to run the tests. * check.sh: Don't check error messages. 2015-07-07 Antonio Diaz Diaz * 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 * 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 * 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 * 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 * 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 * Version 1.2 released. * 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 * 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. * New examples have been added to the manual. 2010-04-05 Antonio Diaz Diaz * Version 1.0 released. * Initial release. * Translated to C from the C++ source of lzip 1.10.
