We are proud to announce the official release of Netrunner 15 'Prometheus'. Netrunner 15 is revised from the ground up - as the first distribution, it officially ships the new KDE Plasma Desktop 5.2. Therefore, an upgrade from previous Netrunner series with KDE 4.x is neither officially available nor really recommended. This release is 64-bit only. What's new? This release features the brand new KDE Plasma Desktop 5.2, packed together with the freshly released KDE Frameworks 5.7 and Qt 5.4. It takes a great deal of Oxygen and a little of Breeze and mixes them into a blend of tradition and modern. All previous settings and add-ons have been carefully restored to work in this new environment. With Netrunner 15 we took the chance to ship a finely revised set of applications.
