An unexpected fifth release candidate of Slackware Linux 11.0 has been announced in the current changelog: "Slackware 11.0 release candidate 5. This is the last one, scout's honor." Last week has brought a fairly large number of updates, including a new Subversion 1.4.0 ("After a couple convincing assurances that this was a safe and ABI/API compatible upgrade, I decided to allow this upgrade."), an svn release of espgs 8.15.3 ("Building from svn fixes two critical problems: missing support for CJK, and not correctly printing umlauts with certain fonts."),security updates to Firefox, Thunderbird and SeaMonkey, as well as many rebuilds of existing package versions to fix bugs or add new functionality. As usual, there are no official ISO images released for download, but a good list of Slackware mirrors can be found here, while a recent unofficial CD image set built from the current tree is available here.
