Now that gtk 2.4.4 has been marked as stable, a bug in xfce4 has shown up where the icons on the iconbar all get clipped (amongst others). The new version of xfce4 (4.0.6) is a purely bugfix version to fix these incompatibilites, and hence I suggest a bump to stable. From www.xfce.org 2004/07/11 The Xfce Team is pleased to announce the release 4.0.6 of the Xfce 4 Desktop Environment and Development Platform. As usual, this is a maintenance release, aimed at bug-fixing; no new features are being added to the 4.0 branch. The main purpose of this release is compatibility with recent GTK+ releases along with other fixes.
Stable version was bumped a while back
