Thanks to the work of John Balcaen (mikala), the main KDE packager on Mageia. Those who use the Cauldron, we invite you to install the new version of KDE to work on possible bugs that may come to appear. According to the roadmap, KDE 4.8 will be available in the next Mageia stable release, Mageia 2, which will be released on May 3. Mageia devs will work to give the community a desktop environment as stable as possible.
Mikala wrote an interesting post about technical questions related to KDE in Mageia. The reading is recommended to those interested.
