Changes in version 1.9:
Changes in version 1.10:
The option '-l, --list' has been ported from lziprecover.
The option '--loose-trailing', has been added.
It is now an error to specify two or more different operations in the
command line (--decompress, --list or --test).
The test used by clzip to discriminate trailing data from a corrupt
header in multimember or concatenated files has been improved to a
Hamming distance (HD) of 3, and the 3 bit flips must happen in different
magic bytes for the test to fail. 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.
