The Xfce project on Saturday afternoon released Xfce 4.10 as the first major Xfce desktop feature release in about sixteen months.
This successor to Xfce 4.8 features a more polished experience for this lightweight desktop environment, a brand new application finder, a vertical display mode option for the Xfce panel, a new MIME type editor, behavioral changes, and the window manager can be configured to tile windows when dragging them to screen edges. There's also Alt-Tab improvements and other functionality improvements.
For more details on the Xfce 4.10 desktop release see
the Xfce.org news announcement and the
Xfce tour that highlights some of the improvements.
