I am pleased to announce the release of plzip 1.6.
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

This release is also GPG signed. You can download the signature by
appending '.sig' to the URL. If the 'gpg --verify' command fails because
you don't have the required public key, then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys 8FE99503132D7742
Key fingerprint = 1D41 C14B 272A 2219 A739 FA4F 8FE9 9503 132D 7742
Changes in version 1.6:
* The option '-l, --list' has been ported from lziprecover.
* It is now an error to specify two or more different operations in
the command line (--decompress, --list or --test).
* In test mode, plzip now continues checking the rest of the files if
any input file is a terminal.

Antonio Diaz, plzip co-author and maintainer.
