Market Place Queue & Engine Updates

Right now there’s alot of great work in the Market Place queue and alot of us are looking forward to.

However with the full 4.6 release is also just on the horizon and the preview is out now I’d like to know from Epic if items in the queue are tested with or have to be 4.6 compliant before release?

Also, is it possible to find out if something on the Market Place is or is not being updated to work with newer versions of the engine?
