Excellent. I'm glad to see this version available, Debian still doesn't have 4.8 in Sid yet. Glad there's another stable distro out there with the latest and greatest!
Still beta so, don't forget .... 
Yep, still, even though it's beta, it's pretty darn good!
Had some problems adding a couple of plugins to the panel, like the battery meter or the keyboard layout ones, wouldn't even show up. However, I did do a source install of XFCE 4.8 under Debian and it would let me add them, but they'd immediately crash, so I imagine there's something amiss upstream somewhere.
