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. +Lziprecover can be used to remove conflicting trailing data from a file. -Compression time of option '-0' has been reduced by 6%. +The contents of a corrupt or truncated header found in a multimember +file is now shown, after the error message, in the same format as +trailing data. -Compression time of options '-1' to '-9' has been reduced by 1%. +Option '-S, --volume-size' now keeps input files unchanged. -Decompression time has been reduced by 7%. +When creating multimember files or splitting the output in volumes, the +dictionary size is now adjusted for each member individually. -In test mode, clzip now continues checking the rest of the files if any -input file is a terminal. +The 'bits/byte' ratio has been replaced with the inverse compression +ratio in the output. -Trailing data are now shown both in hexadecimal and as a string of -printable ASCII characters. +The progress of decompression is now shown at verbosity level 2 (-vv) or +higher. -Three missing chapters have been added to the manual, which now contains -all the chapters of the lzip manual. +Progress of (de)compression is only shown if stderr is a terminal. + +A final diagnostic is now shown at verbosity level 1 (-v) or higher if +any file fails the test when testing multiple files. + +A second '.lz' extension is no longer added to the argument of '-o' if +it already ends in '.lz' or '.tlz'. + +In case of (de)compressed size mismatch, the stored size is now also +shown in hexadecimal to ease visual comparison. + +The dictionary size is now shown at verbosity level 4 (-vvvv) when +decompressing or testing. + +The new chapter "Meaning of clzip's output" has been added to the manual. |
