From the Slackware web site:
Well folks, it's that time to announce a new stable Slackware release again. So, without further ado, announcing Slackware version 12.1! Since we've moved to supporting the 2.6 kernel series exclusively (and fine-tuned the system to get the most out of it), we feel that Slackware 12.1 has many improvements over our last release (Slackware 12.0) and is a must-have upgrade for any Slackware user.

Among the many program updates and distribution enhancements, you'll find better support for RAID, LVM, and cryptsetup; a network capable (FTP and HTTP, not only NFS) installer; and two of the most advanced desktop environments available today: Xfce 4.4.2, a fast, lightweight, and visually appealing desktop environment, and KDE 3.5.9, the latest 3.x version of the full-featured K Desktop Environment.

The official announcement has more details. Also please consider helping to support the project financially at (the CD set and DVD are off to replication, but pre-orders are being taken now). Your kind support and the help of many volunteers is what makes this project possible. Huge thanks are due to everybody who pitched in and helped with bug reports, patches, testing, suggestions, other comments, and everything else. Without this valuable input, Slackware would be nowhere near what it is today. Special thanks to the CREW, to the people developing and testing for (where many of Slackware's future additions are first built and tested), and to everyone on, various #slackware or ##slackware IRC channels, other Slackware related web sites, and other places where the community shares their needs and concerns with the team. On behalf of everyone here, thanks. We think you'll enjoy this new release, and hope that you'll find it to be much more than 0.1 better than Slackware 12.0. ;-)

Have fun!

Pat and the Slackware team
