UE 4.8 Feature list?

I keep hearing about XYZ feature coming with 4.8, but I have not been able to find a clear list or any announcement of any kind, other than the 2 things that are finished on the Trello roadmap and scheduled for release in 4.8, as well as the 2 things in the feature previews from the 7th of March.

Is there a list of new features / bug fixes which will be released?

Its a bit early for that kind of thing, They are still hotfixing 4.7.
