Yesterday, KDE team released version 4.5.3 of the KDE Software Compilation.
I have created Slackware packages for the new release. I am fairly certain that Slackware -current will be updated to this version as well, but at the moment I do not have a time frame for that. Before it gets added, I expect that slackware-current has other updates first.
In the meantime, you can download and install my packages and play around. There are stability and speed improvements so it is strongly advised to update if you were already running my KDE 4.5.2 packages. Just like with the previous set of 4.5.2 packages I created, you do not have to update or install any additional packages. A fully up to date Slackware-current (32-bit or 64-bit) is all you need.
Read the installation/upgrade instructions for my KDE 4.5.3 packages first. Then, get my packages,
