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. + +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. + +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 decompression 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. + +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. |
