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

The sources can be downloaded from http://download.savannah.gnu.org/releases/lzip/lunzip/

The sha256sums are:

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.

If you are distributing software in xz format, please consider using lzip instead. See http://www.nongnu.org/lzip/lzip_benchmark.html#xz1 and http://www.nongnu.org/lzip/xz_inadequate.html
