November 3rd, 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 third in a series of monthly stabilization updates to the 4.5 series. 4.5.3 brings bugfixes and translation updates on top of KDE SC 4.5 series and is a recommended update for everyone running 4.5.2 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 4.5.3 Info Page.

4.5.3 brings a number of improvements:

* KSharedDataCache has cache invalidation bug fixed that caused stability when daylight saving time changed.
* Icon overlays in Dolphin are now positioned correctly after adjusting the zoom level.
* Okular, KDE's universal document viewer has seen improvements in the
DjVu and XPS backends.

The changelog lists more, if not all improvements since 4.5.2:
