I also thought the category chosen for the announcement was rather unusual. I don’t think anyone watches it because support questions are often asked there.
Maybe subcategories in announcements would be better, then you could inform hosting customers and self-hosters (and devs) separately. Everyone is informed about a release, but you can choose whether you want to be informed about all subcategories.
Also, a reply to the topic to bump it after the edit would have been helpful. Otherwise, it’s very easy to miss edits.
