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.

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.
