"The KDE Community is proud to announce KDE Frameworks 5.0. Frameworks 5 is the next generation of KDE libraries, modularized and optimized for easy integration in Qt applications. The Frameworks offer a wide variety of commonly needed functionality in mature, peer reviewed and well tested libraries with friendly licensing terms. There are over 50 different Frameworks as part of this release providing solutions including hardware integration, file format support, additional widgets, plotting functions, spell checking and more. Many of the Frameworks are cross platform and have minimal or no extra dependencies making them easy to build and add to any Qt application," reads the release announcement with many more details on KF5 for interested Qt/KDE developers.

For those wanting to try out this very latest KDE code it should soon be entering the (K)Ubuntu 14.10 archive, there's Project Neon and other PPAs available, Arch Linux users have packages available, and KF5 is coming to Fedora 20 while stable Fedora users have some third-party Copr repositories available.
