Xfce 4.8 Released
PerlDudeXL writes "Today, after almost two years of work, we have the special pleasure of announcing the much awaited release of Xfce 4.8, the new stable version that supersedes Xfce 4.6. [..] Xfce 4.8 is our attempt to update the Xfce code base to all the new desktop frameworks that were introduced in the past few years. We hope that our efforts to drop pieces like ThunarVFS and HAL with GIO, udev, ConsoleKit and PolicyKit will help bringing the Xfce desktop to modern distributions."
Actually dropping HAL for PolicyKit/ConsoleKit/udev makes it considerably lighter in that regard. HAL has always been a beast of a system that got so unwieldy to maintain and fix that they started dismantling it years ago. As far as ThunarVFS vs GIO, I'm not sure, but it shouldn't be much different and at least reduces the amount of code around that duplicates functions, this should at least make your system itself lighter (unless you've got nothing but XFCE apps on your system, in which case there shouldn't be a change).
