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." Check out that dependency graph.
