[Lzip-bug] Plzip 1.12 released

[Antonio Diaz Diaz]

I am pleased to announce the release of plzip 1.12.

Plzip is a massively parallel (multi-threaded) implementation of lzip. Plzip 
uses the compression library lzlib.
Lzip is a lossless data compressor with a user interface similar to the one 
of gzip or bzip2. Lzip uses a simplified form of LZMA (Lempel-Ziv-Markov 
chain-Algorithm) designed to achieve complete interoperability between 
implementations. The maximum dictionary size is 512 MiB so that any lzip 
file can be decompressed on 32-bit machines. Lzip provides accurate and 
robust 3-factor integrity checking. 'lzip -0' compresses about as fast as 
gzip, while 'lzip -9' compresses most files more than bzip2. Decompression 
speed is intermediate between gzip and bzip2. Lzip provides better data 
recovery capabilities than gzip and bzip2. Lzip has been designed, written, 
and tested with great care to replace gzip and bzip2 as general-purpose 
compressed format for Unix-like systems.
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 smaller than 1 MiB plzip is no faster 
than lzip (not even at compression level -0).

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 --recv-keys 8FE99503132D7742

Key fingerprint = 1D41 C14B 272A 2219 A739  FA4F 8FE9 9503 132D 7742


Changes in version 1.12:

  * plzip now exits with error status 2 if any empty member is found in a 
multimember file.
  * Scalability when decompressing to standard output has been increased.

  * The chapter 'Syntax of command-line arguments' has been added to the 
manual.

Please send bug reports and suggestions to lzip-bug@nongnu.org
