I am pleased to announce the release of lziprecover 1.17.

Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz), able to repair slightly damaged files, produce a correct file by merging the good parts of two or more damaged copies, extract data from damaged files, decompress files and test integrity of files.

Lziprecover is able to recover or decompress files produced by any of the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip and pdlzip.

The lzip file format is designed for data sharing and long-term archiving, taking into account both data integrity and decoder availability.

A nice feature of the lzip format is that a corrupt byte is easier to
repair the nearer it is from the beginning of the file. Therefore, with
the help of lziprecover, losing an entire archive just because of a
corrupt byte near the beginning is a thing of the past.

The homepage is at http://www.nongnu.org/lzip/lziprecover.html

The sha1sums are:

This release is also GPG signed. You can download the signature by appending ".sig" to the URL.

Changes in version 1.17:

* Merging files now uses an algorithm similar to the ones used to solve the "Master Mind" game, which makes it much faster. Up to 2 orders of magnitude faster depending on number of files and number of errors. Please, report as a bug any files correctly merged by lziprecover 1.16 that this version can't merge.

  * Repair time has been reduced by 15%.

* The new option "-y, --debug-delay", which finds the max error detection delay in a given range of positions, has been added.

* The new option "-z, --debug-repair", which test repairs a one-byte error at a given position, has been added.

* The targets "install-compress", "install-strip-compress", "install-info-compress" and "install-man-compress" have been added to the Makefile.

  * The chapter "File names" has been added to the manual.

Please send bug reports and suggestions to address@hidden
