The new series includes updates to several of KDE’s core components, notably a port to Qt 4. It will contain a new multimedia API, called Phonon, a device integration framework called Solid and a new style guide and default icon set called Oxygen. It will also include the new desktop and panel user interface tool, called Plasma, which will have support for desktop widgets, similar to SuperKaramba or Apple’s Dashboard widgets. The port to Qt 4 will facilitate support for non-X11-based platforms, including Microsoft Windows and Mac OS X. One of the overall goals of KDE 4 is to be more easily portable to different operating systems.
