Today, three days before the Gran Canaria Desktop Summit starts, the KDE team released KDE 4.3.0 RC1. RC1 is an early candidate for what will become KDE 4.3.0 at the end of this month.
Artwork has now also been merged, and KDE 4.3 will have a new Plasma look, sported by the new, light "Air" Plasma theme. Oxygen, the default in earlier versions of KDE 4 is still available as an option through the "Desktop Settings" dialog. Please give this version some good testing so we can iron out last bugs and make 4.3.0 a smooth release. Note that KDE 4.3.0 RC1 is not suitable for end users.
