KDE Community writes: The KDE Community is proud to announce a Tech Preview of KDE Frameworks 5. Frameworks 5 is the result of almost three years of work to plan, modularize, review and port the set of libraries previously known as KDElibs or KDE Platform 4 into a set of Qt Addons with well-defined dependencies and abilities, ready for Qt 5. This gives the Qt ecosystem a powerful set of drop-in libraries providing additional functionality for a wide variety of tasks and platforms, based on over 15 years of KDE experience in building applications. Today, all the Frameworks are available in Tech Preview mode; a final release is planned for the first half of 2014. Some Tech Preview addons (notably KArchive and Threadweaver) are more mature than others at this time.
