Slackware version 12.2 has been released and available for download from the official project website. From the announcement page:
Among the many program updates and distribution enhancements, you’ll find two of the most advanced desktop environments available today: Xfce 4.4.3, a fast and lightweight but visually appealing and easy to use desktop environment, and KDE 3.5.10, the final 3.x version of the award-winning K Desktop Environment. We have added to Slackware support for HAL (the Hardware Abstraction Layer) which allows the system administrator to add users to the cdrom and plugdev groups. Then they will be able to use items such as USB flash sticks, USB cameras that appear like USB storage, portable hard drives, CD and DVD media, MP3 players, and more, all without
requiring sudo, the mount or umount command. Just plug and play. Properly set up, Slackware’s desktop should be suitable for any level of Linux experience.
