I am pleased to announce the release of lzip 1.26.
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) and is 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.
Lzip is a natural replacement for gzip because lzip is just gzip with a
larger dictionary size, a more efficient entropy coder, and without the
limitations of the gzip format (like the 32-bit uncompressed size).

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, you may download the key from
http://savannah.gnu.org/people/viewgpg.php?user_id=12809 or the GNU keyring
from http://ftpmirror.gnu.org/gnu-keyring.gpg
Key fingerprint = 1E5A EE0B 18C0 DEB4 5D64 AA03 25B6 2C98 2150 1AA0
(This release is signed with a new key because the old 1024-bit DSA key
8FE99503132D7742 is no longer accepted by Debian).
Changes in version 1.26:
* '-dvv' and '-tvv' now print (de)compressed sizes instead of compression
ratio. (Sizes are more informative than compression ratio).
* Large numbers in option arguments are now accepted with underscore
separators (-s 123_456_789).
* Large numbers are now printed with underscore separators (123_456_789).
* '-h' now prints a short help screen containing only the command-line
options. For full help, use '--help'. (Based on suggestions by Murray
Calavera and Adam Tuja).
* '--list' now can safely skip any trailing data added to a lzip file by
the option '--append' of lziprecover.
* '--list' now prints '+t' after the number of members to indicate the
presence of trailing data, and prints the size of the trailing data below
the size of the last member.
* '-lvv' now prints a blank line between the list of members of each
multimember file and the next file.
* Several improvements suggested by John Gilmore have been made to the
manual. Please, review them so that they can be ported to the Internet-Draft
http://datatracker.ietf.org/doc/draft-diaz-lzip/
* 'EXIT STATUS' now has its own section in the man page. (Suggested by
Murray Calavera).
