I am pleased to announce the release of lunzip 1.10.
Lunzip is a decompressor for lzip files. It is written in C and its
small size makes it well suited for embedded devices or software
installers that need to decompress files but do not need compression
capabilities. Lunzip is fully compatible with lzip-1.4 or newer and is
able to decompress any lzip file using as little memory as 50 kB.
The lzip file format is designed for data sharing and long-term
archiving, taking into account both data integrity and decoder availability.
The homepage is at http://www.nongnu.org/lzip/lunzip.html

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 1.10:
* The option '--loose-trailing', has been added.
* The test used by lunzip to discriminate trailing data from a
corrupt header in multimember or concatenated files has been improved to
a Hamming distance (HD) of 3, and the 3 bit flips must happen in
different magic bytes for the test to fail. As a consequence some kinds
of files no longer can be appended to a lzip file as trailing data
unless the '--loose-trailing' option is used when decompressing.
Lziprecover can be used to remove conflicting trailing data from a file.
* The contents of a corrupt or truncated header found in a
multimember file is now shown, after the error message, in the same
format as trailing data.
* The 'bits/byte' ratio has been replaced with the inverse
compression ratio in the output.
* The progress of decompression is now shown at verbosity level 2
(-vv) or higher.
* Progress of decompression is only shown if stderr is a terminal.
* A final diagnostic is now shown at verbosity level 1 (-v) or higher
if any file fails the test when testing multiple files.
* In case of (de)compressed size mismatch, the stored size is now
also shown in hexadecimal to ease visual comparison.
* The dictionary size is now shown at verbosity level 4 (-vvvv) when
decompressing or testing.
