[Lzip-bug] Plzip 1.4 released

[Antonio Diaz Diaz]

I am pleased to announce the release of plzip 1.4.

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.

A nice feature of the lzip format is that a corrupt byte is easier to 
repair the nearer it is from the beginning of the file. Therefore, with 
the help of lziprecover, losing an entire archive just because of a 
corrupt byte near the beginning is a thing of the past.

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

Changes in version 1.4:

  * The option "-0" has been modified to use the new fast encoder of 
lzlib 1.7, which achieves a compression speed and ratio comparable to 
those of pigz's default compression level.
