As a consequence some kinds of files +no longer can be appended to a lzip file as trailing data unless the +'--loose-trailing' option is used when decompressing. +Lzlib 1.10 or newer is required for this test to work on non-seekable +files. +Lziprecover can be used to remove conflicting trailing data from a file. + +The 'bits/byte' ratio has been replaced with the inverse compression +ratio in the output. + +The progress of decompression is now shown at verbosity level 2 (-vv) or +higher. + +Progress of (de)compression is only shown if stderr is a terminal. + +A second '.lz' extension is no longer added to the argument of '-o' if +it already ends in '.lz' or '.tlz'. + +The dictionary size is now shown at verbosity level 4 (-vvvv) when +decompressing or testing. + +The new chapter "Meaning of plzip's output", and a block diagram of +plzip have been added to the manual. |
