I’ve just pushed the relevant buttons to make the release of 4.6.0 a public fact. Packages should appear shortly for your favourite operating system, I know that openSUSE packages are available from Factory now, so start your zypper already.
The release is actually a pretty big thing, it adds a lot of new features, some of which very visible, others being less noticable. There’s the mobile profile for example, which makes it much easier to use KDE frameworks in your mobile application. Then we have the re-vamped activity manager, that adds a way to group applications in their context and makes it possible to manage these activities like sessions. So head over and read what’s new in the Plasma Workspaces, the applications and the KDE development platform.
