As scheduled the first beta of KDE 4 was released a few days ago. This is the first step toward integrating the new technologies of KDE 4 in the new applications. The beta namely marks the freezing of the library interface. This means that there will be no more changes (if not extremely essential) to the libraries and that the application developers can start integrating the new powerful functions of the KDE 4 without having to worry about changes to the libraries. Konsole, Okular, KWin, Dolpin, Konqueror, Gwenview, (and the rest) have all been updated with new features and tighter integration. More detailed information is in the KDE press release.
