xfce 4.10 has recently been released but I cannot find a supported ppa available yet. There is this ppa https://launchpad.net/~xubuntu-dev/+archive/xfce-4.10 but it still remains empty.

Does anyone have any news on when/where an official ubuntu build will be released?

  • correct - its just been released. Suggest contact the developers as to their release schedule. This is really too localised to be answered here hence I'm closing the question. – fossfreedom Apr 30 '12 at 9:40
