I would suggest adding a separate subforum under Official announcements named Changelogs. Each time there is a changelog, make a new thread, like you do in Nightly Builds
Reason for this is, that I l would like to set up RSS reader that would post notification on our Discord when you guys post post an update post. Currently it is not possible due to how this forum software's RSS feed works: It only lists threads and you can monitor if a new thread is posted
