Add updated field to Message #8
Description
This seems to be the only way to be able to tell if a notification over the websocket is to look for the presence of the updated field (although I haven't been able to tell whether it's possible notifications will be batched, leading a quick edit to mean you only receive the edited message, hopefully not). I'd therefore like the updated field to be added the the Message struct.
If you're happy with the change, I can raise a PR for it.
