Slackware 14 has been released today, wrapping up 17 long months of development. Read the announcement to learn all about this new release.The Slackware homepage has some more information for you, as well.
I think there has not been such a long series of release candidates, ever before. Thanks to the co-operation of our Slackware user base, there has been a tremendous amount of beta testing during the past few months. Pat could probably have gone on releasing updates and allow further testing for months to come, but essentially, we have a solid and stable Slackware release in our hands.
