The Manager does a reasonable job identifying patches available for a given version. The Issues page on GitHub has a lot of the bugs laid out. The Releases tab also has the update notes and the website has the patch notes (including required version).
On the Discord, #announcements has the major update info. #support acts quite a lot like the old Reddit page where people post issues they've run into with threaded replies. I agree having a ReVanced Lemmy page would be better than Discord but Discord Posts are shockingly usable imo. Chat and Off-Topic are obviously horrifically unsearchable chatrooms but also aren't the only resources on the server.
My response would be "This must be illegal under GDPR"
