openSUSE 12.3 was officially released today. It brings updated desktop environments and software, lot of polishing, a brand new KDE theme, complete systemd integration, and many other features.
As usual, SUSE Studio supports the new openSUSE release from day one. Just click the Create appliance link after you log in and select the template you would like to start with.

UpgradeYou can also upgrade your older appliances to 12.3 easily. Just go to the Start tab and click the Upgrade button in the bar at the top.
Studio will try to change repositories in your appliance to their 12.3 equivalents and add or remove few packages to ensure everything works smoothly. You can see what exactly was done in the log accessible from the bar at the bottom of the Start tab.
Sometimes the upgraded appliance will need few manual tweaks to work. Just inspect the log, see what was changed, and apply any additional adjustments.
If you are not satisfied with the upgrade, you can always revert to the original version by clicking the Undo upgrade link.
