I am pleased to announce the release of lzip 1.19.

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.

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 1.19:

  * The option '-l, --list' has been ported from lziprecover.

* It is now an error to specify two or more different operations in the command line (--decompress, --list or --test).

  * Compression time of option '-0' has been slightly reduced.

  * Decompression time has been reduced by 2%.

* In test mode, lzip now continues checking the rest of the files if any input file is a terminal.

* Trailing data are now shown both in hexadecimal and as a string of printable ASCII characters.
