[Lzip-bug] Lzip 1.21 released

[Antonio Diaz Diaz]

I am pleased to announce the release of lzip 1.21.

Lzip is a lossless data compressor with a user interface similar to the 
one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0) 
or compress most files more than bzip2 (lzip -9). Decompression speed is 
intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 
from a data recovery perspective. Lzip has been designed, written and 
tested with great care to replace gzip and bzip2 as the standard 
general-purpose compressed format for unix-like systems.

The lzip file format is designed for data sharing and long-term 
archiving, taking into account both data integrity and decoder availability:

   * The lzip format provides very safe integrity checking and some data
     recovery means. The lziprecover program can repair bit flip errors
     (one of the most common forms of data corruption) in lzip files,
     and provides data recovery capabilities, including error-checked
     merging of damaged copies of a file.

   * The lzip format is as simple as possible (but not simpler). The
     lzip manual provides the source code of a simple decompressor
     along with a detailed explanation of how it works, so that with
     the only help of the lzip manual it would be possible for a
     digital archaeologist to extract the data from a lzip file long
     after quantum computers eventually render LZMA obsolete.

   * Additionally the lzip reference implementation is copylefted, which
     guarantees that it will remain free forever.

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 1.21:

  * Detection of forbidden combinations of characters in trailing data 
has been improved.

  * Errors are now also checked when closing the input file.

  * Lzip now compiles on DOS with DJGPP. (Patch from Robert Riebisch).

  * The descriptions of '-0..-9', '-m' and '-s' in the manual have been 
improved.

  * The configure script now accepts appending options to CXXFLAGS 
using the syntax 'CXXFLAGS+=OPTIONS'.

  * It has been documented in INSTALL the use of
    CXXFLAGS+='-D __USE_MINGW_ANSI_STDIO' when compiling on MinGW.
