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
	  multi-member 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): Do not show the message
	  " and '--stdout' was not specified" for directories, etc.
	* New examples have been added to the manual.
