Today we released Kubuntu 10.04 LTS. This is the first Long Term Support release to feature KDE 4 Platform and Applications. It's very exciting that the long journey to KDE 4 has come to the level of stability where we can call it LTS.
A big thank you to the hard working Kubuntu team, too many to name but they have toiled day and night over the last 6 months to make sure you have the latest software with the minimum of bugs.
