The KDE team today released KDE 4.1. The KDE developers, including the openSUSE KDE Team, have been working on it for the last six months. Lots of feedback from people trying out KDE 4.0 has gone into KDE 4.1, filling most of the gaps people experienced with the 4.0 releases. See the release announcement for more information and screenshots.
KDE 4.1 Packages, openSUSE-based KDE 4.1 Live CD
Regular KDE 4 Packages and an openSUSE-based KDE Four Live CD have been available throughout the whole cycle, and final versions of them are also available now. On openSUSE 11.0 you can use 1-click-install to get the KDE 4.1 desktop environment (for openSUSE 10.3 follow above link):
Or you can choose to install a more basic KDE 4 desktop. Developers can also optionally install the KDE 4 build dependencies: all the packages you need to have installed for compiling KDE 4.x from source (experts only).
