[Lzip-bug] Plzip 1.3 released

[Antonio Diaz Diaz]

I am pleased to announce the release of plzip 1.3.

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. 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 1.3:

  * Testing of a non-seekable file or of standard input now uses up to 
30 MiB less memory per thread.

  * "-dvvv" and "-tvvv" now show the dictionary size of the first 
member, producing the same output as lzip for single-member files.

  * Chapters "Memory requirements" and "Minimum file sizes" have been 
added to the manual.

  * The targets "install-compress", "install-strip-compress", 
"install-info-compress" and "install-man-compress" have been added to 
the Makefile.
