Release notes in Announcements are not the release note (not all of them)

Devs – please conform the release notes in the Announcements section with the actual release notes in Help inside Obsidian. It’s helpful to be consistent, and also have a place to point non-users to go to read about what’s new.

Also, the release notes for 0.7.3 in Help (and here) are not the release notes in Discord. Maybe a single canonical source is needed and everything links to that source?
