Definitely not new. I wouldn’t exclude the possibility that some users were not offered it, though.
If you want to take a look at it, the official Discourse site has a “sandbox” forum used for demoing the software, where anybody can register a new user and their discobot will take it through the tutorial.
I think they reset their sandbox every day, though, so make sure to satisfy your curiosity before it all turns into a pumpkin!
