Today, KDE updated the Applications, Platform and Plasma Workspaces to 4.5.1, a new releases bringing a number of important bugfixes on top of 4.5.0. 4.5.0 was released only three weeks ago and receives monthly service updates. 4.5.1 is the first in this series of bugfix and translation updates. Those releases improve stability and the user experience further, while not bringing major new features or bigger changes to the user interface. 4.5.1 is a safe upgrade for anybody running 4.5.0 or earlier versions. 4.5.1 has been dubbed "Cronjob" as it is one of the regular releases published by KDE, just like a cronjob does.
