KDE SC 4.4.2 (second maintenance release for the 4.4 series ) has been made available and the Slackware packages can be found at http://alien.slackbook.org/ktown/4.4.2/
You can download 32-bit as well as 64-bit packages. Many of the dependencies have been updated, some have been added. Read the README in the top-directory for full installation/upgrade instructions, or look for my older http://alien.slackbook.org/blog/its-been-released-kde-sc-4-4-0/ post.
Note that you have to be running Slackware-current (not older than 30-march-2010) or lots of things will break!
As a special gift on april 1st, I have added PolicyKit and ConsoleKit to the dependencies section. The KDE SC 4.4.2 packages have been built with support for them, which means you can now properly set your date/time in KDE, as well as install new fonts and configure your printer… thanks to the work of PiterPUNK and Robby Workman, and NaCl (from the WICD developer team) who wrote and refined the patch for polkit-1 that allowed me to add it without the need for PAM.
This upgrade is recommended if you are using my earlier 4.4.x packages.
