I am pleased to announce the release of plzip 1.5.
Plzip is a massively parallel (multi-threaded) lossless data compressor
based on the lzlib compression library, with a user interface similar to
the one of lzip, bzip2 or gzip.
Plzip can compress/decompress large files on multiprocessor machines
much faster than lzip, at the cost of a slightly reduced compression
ratio (0.4 to 2 percent larger compressed files). Note that the number
of usable threads is limited by file size; on files larger than a few GB
plzip can use hundreds of processors, but on files of only a few MB
plzip is no faster than lzip.
Plzip uses the lzip file format; the files produced by plzip are fully
compatible with lzip-1.4 or newer, and can be rescued with lziprecover.
The lzip file format is designed for data sharing and long-term
archiving, taking into account both data integrity and decoder availability.
The homepage is at http://www.nongnu.org/lzip/plzip.html
The sources can be downloaded from

The sha1sums are:
132fc5f565fab5d7d019e73fe613013169fcce86 plzip-1.5.tar.lz
0d62982d993305698717aee228df7996aa02c23f plzip-1.5.tar.gz
This release is also GPG signed. You can download the signature by
appending ".sig" to the URL.
Changes in version 1.5:
* The option "-a, --trailing-error", which makes plzip exit with
error status 2 if any remaining input is detected after decompressing
the last member, has been added.
* When decompressing, the file specified with the '--output' option
is now deleted if the input is a terminal.
* The new chapters "Trailing data" and "Examples" have been added to
the manual.
* A harmless check failure on Windows, caused by the failed
comparison of a message in text mode, has been fixed.

Antonio Diaz, plzip co-author and maintainer.
