Unreal Engine 4.10 Released!

[=;421525]
so far 4.10 has really messed me up… i cant build lighting at all… tons of problems… Fails right when you click build … though swarm agent continues running with a progress bar, but the editor already failed… And if i try to use swarm coordinator with otehr agents… it will even kick me out of the unreal edtior… like instant no message crash.
