The KDE team recently announced the release of second beta of KDE SC 4.11, which includes Workspaces (desktop environment), Applications and development platform.
If you are an openSUSE user you can easily test KDE 4.11 as the packages are available through a repo. Just keep in mind that it’s a beta software so things might be buggy so use it only if you are willing to help the teams in finding and fixing bugs.
Just add KDE’s Core and Extra repos on your system and then upgrade the specific repos of your system.
