I am pleased to announce the release of lzlib 1.7.

Lzlib is a compression library providing in-memory LZMA compression and decompression functions, including integrity checking of the decompressed data. The compressed data format used by lzlib is the lzip format. Lzlib is written in C.

Compression/decompression is done by repeatedly calling a couple of read/write functions until all the data have been processed by the library. This interface is safer and less error prone than the traditional zlib interface.

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/lzlib.html

The sources can be downloaded from

The sha1sums are:
50c657edfdc2c78e2b773d4fad68142c4d67a0ba  lzlib-1.7.tar.lz
1d29625cc3d558c6c961d5314402e692a7eacea2  lzlib-1.7.tar.gz

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

Changes in version 1.7:

* The fast encoder, which produces a compression speed and ratio comparable to those of gzip, has been ported from lzip.

  * The option "-0" has been ported from lzip to minilzip.

* If all the data to be compressed are written in advance, lzlib will automatically adjust the header of the compressed data to use the smallest possible dictionary size. This feature reduces the amount of memory needed for decompression and allows minilzip to produce identical compressed output as lzip.

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

Please send bug reports and suggestions to address@hidden
