Another month, another update to the KDE 4.0 series. This time, we are presenting KDE 4.0.4, dubbed File-Not-Found to the audience. KDE 4.0.4 brings improvements to KHTML, Okular and various other components. We recommend that people who are already running KDE 4.0 releases update to 4.0.4. The emphasis of this release lies, as usual in stabilising, bugfixing, performance improvements and updated translations -- no new features. The developers have again squashed quite some bugs which you can find some of in the changelog. With this release, the KDE community continues to support the KDE 4.0 series that has been released for brave users earlier this year. KDE 4.1, to be released this summer (in the northern-hemisphere) will bring new features and applications. KDE 4.1 is based on the recently released Qt 4.4 while KDE 4.0.4 is still based on Qt 4.3 as is the case with the whole KDE 4.0 series. So put on your update shoes and install 4.0.4 today.
