|
|
|
|

|
|
* Removed decompression support for version 0 files.

|
|
|
|
* 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.

|
|
|
|
* 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%.

|
|
* Makefile.in: 'make install' no more tries to run

|
'/sbin/ldconfig' on systems lacking it.

|
been changed to match those of lzip 1.11.
