That is really hard to do, because as soon as Master on GitHub is updated, the changelog channel in Discord lets everyone know it is posted, so the "cat is out of the bag" so to speak. You have to update master before you do all of the builds.
Having a feed into a tight-knit platform like discord is different than a public post. I think we really have to nail down the release process, particularly as though we were someone from the outside looking in.
Still, great release!
Edit add: I don't think it's about letting the cat out of the bag, it's more of a image/marketing/ux thing.
