Netrunner, a GNU/Linux distribution based on Kubuntu, featuring KDE as the default desktop environment, and integrating many GNOME/GTK+ programs to make it Ubuntu compatible, is now at version 4.2 RC.
Netrunner 4.2 RC, codenamed Dryland, was announced by the developers, but so far only the 32-bit version is available for testing. It has a few problems, such as the installer crashing with crypt home, PCM volume slider setting to zero after reboot, and some others.
Among the new features in this RC version we can mention Linux kernel 3.2, KDE SC 4.8.2, improved Firefox-KDE-Integration, improved GTK2/3-KDE-Integration (via oxygen-gtk), and The GIMP 2.8.
Download Netrunner 4.2 RC right now from Softpedia. Remember that this is a development release and it should NOT be installed on production machines. It is intended to be used for testing purposes only.
