Mon Apr 25 13:37:00 UTC 2011 Slackware 13.37 x86_64 stable is released! Thanks to everyone who pitched in on this release: the Slackware team, the folks producing upstream code, and linuxquestions.org for providing a great forum for collaboration and testing. The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. Please consider supporting the Slackware project by picking up a copy from store.slackware.com. We're taking pre-orders now, and offer a discount if you sign up for a subscription. As always, thanks to the Slackware community for testing, suggestions, and feedback. :-) Have fun!
