No MHL 3.0 support? What about OTG?

I currently have a Note edge and have been looking at edge+ and note 5. I've seen a few post on xda stating that neither phone supports MHL 3.0 is this true, also do they still support OTG? I can deal without MHL due to chomecast and screen mirroring but I have to have OTG support especially since they ditched micro SD. Can anyone confirm both for me thanks.
