I am pleased to announce the release of pdlzip 1.15.
Pdlzip is a permissively licensed implementation of the lzip data
compressor, intended for those who can't distribute (or even use) GPL
licensed Free Software. The name of pdlzip comes from 'public domain lzip'.
Pdlzip is written in C.
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.
Pdlzip is also able to decompress legacy lzma-alone (.lzma) files.
Pdlzip includes public domain (de)compression code from the LZMA SDK
(Software Development Kit) written by Igor Pavlov.

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 1.15:
* '-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'.
* 'EXIT STATUS' now has its own section in the man page.
