I am pleased to announce the release of pdlzip 1.10.

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 and is (hope)fully compatible with lzip 1.4 or newer.

Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0) or compress most files more than bzip2 (lzip -9). Decompression speed is intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 from a data recovery perspective.

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

Pdlzip is also able to decompress legacy lzma-alone (.lzma) files. Lzma-alone is a very bad format; it is essentially a raw LZMA stream. If you keep any lzma-alone files, it is advisable to recompress them to lzip format. Lziprecover can convert some lzma-alone files to lzip format without recompressing.

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, 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:

* Compression level '-0' now uses a dictionary size of 64 KiB instead of 1 MiB.

  * Errors are now also checked when closing the input file.

  * Pdlzip now compiles on DOS with DJGPP. (Patch from Robert Riebisch).

* The configure script now accepts appending options to CFLAGS using the syntax 'CFLAGS+=OPTIONS'.

  * It has been documented in INSTALL the use of
    CFLAGS+='-D __USE_MINGW_ANSI_STDIO' when compiling on MinGW.

If you care about long-term archiving, please help me replace xz with lzip. See http://www.nongnu.org/lzip/lzip_benchmark.html#xz1
