Odd how no one has mentioned the addition of client side decorations. Personally it's a huge dealbreaker for me, I really dislike how they look. It's a shame, because the release and Xfce in general otherwise seems really good. Guess I'll stick to MATE for now.
Yeah I agree, I been using XFCE for many years but I think that CSD is a bad move! I hope they at least remove search bar from titles. If they don't improve it, I may have to switch to i3.
