2013-10-07  Antonio Diaz Diaz  <antonio@gnu.org>

	* Version 1.6-pre1 released.

	* Makefile.in: Ignore errors from ldconfig.

2013-09-15  Antonio Diaz Diaz  <antonio@gnu.org>

	* Version 1.5 released.
	* Removed decompression support for version 0 files.
	* The LZ_compress_sync_flush mechanism has been fixed (again).
	* Minor fixes.

2013-05-28  Antonio Diaz Diaz  <antonio@gnu.org>

	* Version 1.4 released.
	* Multi-step trials have been implemented.
	* Compression ratio has been slightly increased.
	* Compression time has been reduced by 8%.
	* Decompression time has been reduced by 7%.
	* lzlib.h: Changed 'long long' values to 'unsigned long long'.
	* encoder.c (Mf_init): Reduce minimum buffer size to 64KiB.
	* lzlib.c (LZ_decompress_read): Tell LZ_header_error from
	  LZ_unexpected_eof the same way as lzip does.
	* 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.

2012-02-29  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 1.3 released.
	* Translated to C from the C++ source of lzlib 1.2.
	* configure: 'datadir' renamed to 'datarootdir'.

2011-10-25  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 1.2 released.
	* 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.cc: Optimize pair price calculations. This
	  reduces compression time for large values of '--match-length'
	  by up to 6%.
	* main.cc: Added new option '-F, --recompress'.
	* Makefile.in: 'make install' no more tries to run
	  '/sbin/ldconfig' on systems lacking it.

2011-01-03  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 1.1 released.
	* Compression time has been reduced by 2%.
	* All declarations not belonging to the API have been
	  encapsulated in the namespace 'Lzlib'.
	* testsuite: 'test1' renamed to 'test.txt'. Added new tests.
	* Match length limits set by options -1 to -9 of minilzip have
	  been changed to match those of lzip 1.11.
	* main.cc: Set stdin/stdout in binary mode on OS2.
	* bbexample.cc: New file containing example functions for
	  buffer-to-buffer compression/decompression.

2010-05-08  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 1.0 released.
	* Added new function LZ_decompress_member_finished.

	* Variables declared 'extern' have been encapsulated in a
	  namespace.
	* main.cc: Fixed warning about fchown's return value being ignored.
	* decoder.h: Input_buffer integrated in Range_decoder.

2010-02-10  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 0.9 released.
	* Compression time has been reduced by 8%.

2010-01-17  Antonio Diaz Diaz  <ant_diaz@teleline.es>

	* Version 0.8 released.
	* Added new function LZ_decompress_reset.
	* Added new function LZ_decompress_sync_to_member.
	* Added new function LZ_decompress_write_size.
	* Added new function LZ_strerror.
	* lzlib.h: API change. Replaced 'enum' with functions for values
	  of dictionary size limits to make interface names consistent.
	* lzlib.h: API change. 'LZ_errno' replaced with 'LZ_Errno'.
	* lzlib.h: API change. Replaced 'void *' with 'struct LZ_Encoder *'
	  and 'struct LZ_Decoder *' to make interface type safe.
	* decoder.cc: Truncated member trailer is now correctly detected.
	* encoder.cc: Matchfinder::reset now also clears at_stream_end_,
	  allowing LZ_compress_restart_member to restart a finished stream.
	* lzlib.cc: Accept only query or close operations after a fatal
	  error has occurred.
	* Shared version of lzlib is no more built by default.
	* testsuite/check.sh: Use 'test1' instead of 'COPYING' for testing.
