KDE proudly announced the latest stable and bug fix release for 4.5 series.
December 2nd, 2010. Today, KDE has released a series of updates to the Plasma Desktop and Netbook workspaces, the KDE Applications and the KDE Platform. This update is the fourth in a series of monthly stabilization updates to the 4.5 series. 4.5.4 brings bugfixes and translation updates on top of KDE SC 4.5 series and is a recommended update for everyone running 4.5.3 or earlier versions. As the release only contains bugfixes and translation updates, it will be a safe and pleasant update for everyone. KDE SC 4 is already translated into more than 55 languages, with more to come. To download source code or packages to install go to the 4.5.4 Info Page. The changelog lists more, but not all improvements since 4.5.3.
As of now factory repos are updated with KDE4.6 beta. If you want to try out this bleeding edge software and help the developers to send bug reports, this article can guide you to install latest KDE 4.6 beta in openSUSE 11.3.
