I am pleased to announce the release of plzip 1.0.

Plzip is a massively parallel (multi-threaded), lossless data compressor based on the lzlib compression library, with very safe integrity checking and a user interface similar to the one of bzip2, gzip or lzip.

Plzip is intended for faster compression/decompression of big files on multiprocessor machines, which makes it specially well suited for distribution of big software files and large scale data archiving. On files big enough (several GB), plzip can use hundreds of processors.

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 homepage is at http://www.nongnu.org/lzip/plzip.html

The sources can be downloaded from

The md5sums are:
dc21cd02a22ed104eb7fbe0153491db7  plzip-1.0.tar.lz
756c31990c0957a37e2ce6e1ba780853  plzip-1.0.tar.gz

This release is also GPG signed. You can download the signature by appending ".sig" to the URL.

Changes in version 1.0:

* Scalability of compression (max number of useful worker threads) has been increased.

* Scalability when decompressing from/to regular files has been increased.

* The number of worker threads is now limited to the number of members in the input file when decompressing from a regular file.

  * "configure" now accepts options with a separate argument.

  * The target "install-as-lzip" has been added to the Makefile.

  * The target "install-bin" has been added to the Makefile.
