I'm at work, so I haven't been able to play around with it much yet. I'm in the middle of restoring my apps. I have, however, noticed that a few icons in the menus have changed (for the better). And according to the list of files changed/added, it appears that two new themes have been added, bringing the total up to four. I also noticed two new packages listed, camera-test and microphone-test. I don't know if these are actual programs though as I haven't seen them listed in my menus.. but that could be because I restored from a backup?

More as I find it.
