I am pleased to announce the release of clzip 1.1.
Clzip is a lossless data compressor based on the LZMA algorithm, with
very safe integrity checking and a user interface similar to the one of
gzip or bzip2.
Clzip uses the lzip file format; the files produced by clzip are fully
compatible with lzip-1.4 or newer. Clzip is in fact a C language version
of lzip, intended for embedded devices or systems lacking a C++ compiler.
The homepage is at http://www.nongnu.org/lzip/clzip.html
The sources can be downloaded from
http://download.savannah.gnu.org/releases/lzip/.
The md5sums are:
5d6dd51e4ef4dff3a092ded660005d1d clzip-1.1.tar.gz
9a55b5b46efbe6b67c39fffcffd0bfea clzip-1.1.tar.lz
This release is also GPG signed. You can download the signature by
appending ".sig" to the URL.
Changes in version 1.1:
* Code has been converted to "C89 + long long". A C99 compiler is no
more needed.
* A warning about fchown's return value being ignored has been fixed.
* "clzip -tvvvv" now shows file compression ratio.
* Match length limit set by options -1 to -8 has been reduced to
extend range of use towards gzip. Lower numbers now compress less but
faster. (-1 now takes 43% less time for only 20% larger compressed size).
* (Note that the bidimensional parameter space of LZMA can't be
mapped to a linear scale optimal for all files. If your files are large,
very repetitive, etc, you may need to use the --match-length and
--dictionary-size options directly to achieve optimal performance).
* Compression of option -9 has been slightly increased.
* Do not show the message "and `--stdout' was not specified" for file
types that can't be read (directories, etc).
* Some new examples have been added to the manual.
Please send bug reports and suggestions to [email protected]
If you are packaging clzip for a distribution, please, try to use the
lzipped source tarball, as this can improve the support for the lzip
format in packaging systems[1][2]. Thanks.
