No new ocean types generate.

When I generate a new world in the latest snapshot, only normal Oceans and Deep Oceans generate, but not the new warm, cold and frozen oceans (including Deep variants). I do not know if this is truly a bug, because I've seen a lot of video's about the new snapshot that do have these oceans, but I don't know if these are newly generated worlds.

I haven't attached any screenshots, because I think the description explains it.
