November 7 The Xfce Development Team announced a preview release of what will become Xfce 4.8. Amongst the things that have changed since 4.6 is that Xfce has been ported to use GIO instead of ThunarVFS and that the dependency of HAL has been replaced with more modern technologies like udev, PolicyKit and ConsoleKit. The Xfce panel has also been rewritten from scratch to provide better support for multiple monitors amongst other things.
Some of the things still waiting to be implemented is gridless placement of icons on the desktop and a netbook friendly settings dialog.
The final Xfce 4.8 is set to be released on January 16 2011.
