Just for those wondering (or whose advanced CSS differences tool times out still), I ran the tool and there are no changes to the advanced CSS at all since RC2.

That doesn't surprise me

I used rc3. but i haven't upgrade yet.

It doesn't surprise me that much, but I thought maybe here or there may be a tiny change. But anyway so I guess people who skinned in the RC phase won;t have to add any final touches.

No css changes that I can recall since RC2 or RC3.

Cool, that makes life easier :D

I only have a few skin edits to sort out and then to remove the last of the blue (from the new CSS for 2.2 and the new images in 2.2)

I had already skinned using rc3, and have 3 skins ready.
