What is "Unreal Engine 4 Integration 1.29"?

Hi all!

Sometimes I have read on the newsletters about UE integration, but I would want to ask you about what that it means. I'm an UE4 developer: Must I install something special for recognicing the devide or their functions and blueprints? Something to do with the "UE Integration"? They say that 4 new blueprints have been added and this breaks my mind: added to UE? I mean, if it's an Oculus Update, how can Oculus add new blueprints to Unreal? Shouldn't be an independent update from Epic to Unreal?

(Oh, I'm waiting for my headsets, so I would want to be ready when they arrive).

Thank you very much!
