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 longer tries to run '/sbin/ldconfig' on systems lacking it. 2011-01-03 Antonio Diaz Diaz * 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'.

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 longer built by default. * check.sh: Use 'test1' instead of 'COPYING' for testing. 2009-10-20 Antonio Diaz Diaz * Version 0.7 released. * Compression time has been reduced by 4%. * check.sh: Removed -9 to run in less than 256MiB of RAM. * lzcheck.cc: Read files of any size up to 2^63 bytes. 2009-09-02 Antonio Diaz Diaz * Version 0.6 released. * The LZ_compress_sync_flush mechanism has been fixed. 2009-07-03 Antonio Diaz Diaz * Version 0.5 released. * Decompression speed has been improved. * main.cc (signal_handler): Declared as 'extern "C"'. 2009-06-03 Antonio Diaz Diaz * Version 0.4 released. * Added new function LZ_compress_sync_flush. * Added new function LZ_compress_write_size. * Decompression speed has been improved. * Added chapter 'Buffering' to the manual. 2009-05-03 Antonio Diaz Diaz * Version 0.3 released. * Lzlib is now built as a shared library (in addition to static). 2009-04-26 Antonio Diaz Diaz * Version 0.2 released. * Fixed a segfault when decompressing trailing garbage. * Fixed a false positive in LZ_(de)compress_finished. 2009-04-21 Antonio Diaz Diaz * Version 0.1 released.
