12017-04-13 Antonio Diaz Diaz <antonio@gnu.org> 2 3 * Version 1.9 released. 4 * The option '-l, --list' has been ported from lziprecover. 5 * Don't allow mixing different operations (-d, -l or -t). 6 * Compression time of option '-0' has been reduced by 6%. 7 * Compression time of options -1 to -9 has been reduced by 1%. 8 * Decompression time has been reduced by 7%. 9 * main.c: Continue testing if any input file is a terminal. 10 * main.c: Show trailing data in both hexadecimal and ASCII. 11 * file_index.c: Improve detection of bad dict and trailing data. 12 * lzip.h: Unified messages for bad magic, trailing data, etc. 13 * clzip.texi: Added missing chapters from lzip.texi. 14 152016-05-13 Antonio Diaz Diaz <antonio@gnu.org> 16 17 * Version 1.8 released. 18 * main.c: Added new option '-a, --trailing-error'. 19 * main.c (decompress): Print up to 6 bytes of trailing data 20 when '-vvvv' is specified. 21 * decoder.c (LZd_verify_trailer): Removed test of final code. 22 * main.c (main): Delete '--output' file if infd is a terminal. 23 * main.c (main): Don't use stdin more than once. 24 * clzip.texi: Added chapter 'Trailing data'. 25 * configure: Avoid warning on some shells when testing for gcc. 26 * Makefile.in: Detect the existence of install-info. 27 * testsuite/check.sh: A POSIX shell is required to run the tests. 28 * testsuite/check.sh: Don't check error messages. 29 302015-07-07 Antonio Diaz Diaz <antonio@gnu.org> 31 32 * Version 1.7 released. 33 * Ported fast encoder and option '-0' from lzip. 34 * Makefile.in: Added new targets 'install*-compress'. 35 362014-08-28 Antonio Diaz Diaz <antonio@gnu.org> 37 38 * Version 1.6 released. 39 * Compression ratio of option '-9' has been slightly increased. 40 * main.c (close_and_set_permissions): Behave like 'cp -p'. 41 * clzip.texinfo: Renamed to clzip.texi. 42 * License changed to GPL version 2 or later. 43 442013-09-17 Antonio Diaz Diaz <antonio@gnu.org> 45 46 * Version 1.5 released. 47 * Show progress of compression at verbosity level 2 (-vv). 48 * main.c (show_header): Don't show header version. 49 * Ignore option '-n, --threads' for compatibility with plzip. 50 * configure: Options now accept a separate argument. 51 522013-02-18 Antonio Diaz Diaz <ant_diaz@teleline.es> 53 54 * Version 1.4 released. 55 * Multi-step trials have been implemented. 56 * Compression ratio has been slightly increased. 57 * Compression time has been reduced by 10%. 58 * Decompression time has been reduced by 8%. 59 * Makefile.in: Added new target 'install-as-lzip'. 60 * Makefile.in: Added new target 'install-bin'. 61 * main.c: Use 'setmode' instead of '_setmode' on Windows and OS/2. 62 * main.c: Define 'strtoull' to 'strtoul' on Windows. 63 642012-02-25 Antonio Diaz Diaz <ant_diaz@teleline.es> 65 66 * Version 1.3 released. 67 * main.c (close_and_set_permissions): Inability to change output 68 file attributes has been downgraded from error to warning. 69 * encoder.c (Mf_init): Return false if out of memory instead of 70 calling cleanup_and_fail. 71 * Small change in '--help' output and man page. 72 * Changed quote characters in messages as advised by GNU Standards. 73 * configure: 'datadir' renamed to 'datarootdir'. 74 752011-05-18 Antonio Diaz Diaz <ant_diaz@teleline.es> 76 77 * Version 1.2 released. 78 * main.c: Added new option '-F, --recompress'. 79 * main.c (decompress): Print only one status line for each 80 multimember file when only one '-v' is specified. 81 * encoder.h (Lee_update_prices): Update high length symbol prices 82 independently of the value of 'pos_state'. This gives better 83 compression for large values of '--match-length' without being 84 slower. 85 * encoder.h encoder.c: Optimize pair price calculations. This 86 reduces compression time for large values of '--match-length' 87 by up to 6%. 88 892011-01-11 Antonio Diaz Diaz <ant_diaz@teleline.es> 90 91 * Version 1.1 released. 92 * Code has been converted to 'C89 + long long' from C99. 93 * main.c: Fixed warning about fchown return value being ignored. 94 * decoder.c: '-tvvvv' now shows compression ratio. 95 * main.c: Match length limit set by options -1 to -8 has been 96 reduced to extend range of use towards gzip. Lower numbers now 97 compress less but faster. (-1 now takes 43% less time for only 98 20% larger compressed size). 99 * Compression ratio of option '-9' has been slightly increased. 100 * main.c (open_instream): Don't show the message 101 " and '--stdout' was not specified" for directories, etc. 102 * New examples have been added to the manual. 103 1042010-04-05 Antonio Diaz Diaz <ant_diaz@teleline.es> 105 106 * Version 1.0 released. 107 * Initial release. 108 * Translated to C from the C++ source of lzip 1.10. 109 110 111Copyright (C) 2010-2017 Antonio Diaz Diaz. 112 113This file is a collection of facts, and thus it is not copyrightable, 114but just in case, you have unlimited permission to copy, distribute and 115modify it. 116
