Is this a good issue to subscribe to to get notifications for progress towards stable v9 rooms?

@tombh No, this PR is about the room upgrade mechanism specifically. I have been working on v8 and v9 rooms today though.

Oh great! Is there somewhere I can subscribe for updates? (I'd rather not subscribe to the whole repo)
