KDE has released betas of the new versions of Applications and the KDE Development Platform. With API, dependency and feature freezes in place, the KDE team's focus is now on fixing bugs and further polishing.
This release does not include Plasma Workspaces, which was frozen for new features in its 4.11 series. The Development Platform has been virtually frozen for a number of releases in anticipation of KDE Frameworks 5. So this release is mainly about improving and polishing Applications.
