We’re going to want an archive of changes but allow a place for people to give feedback for a specific build. What I’m thinking of is pinning two posts:
Most Recent Beta Release Notes
Archived Beta Release Notes
That way, the most recent one is accessible and people can discuss that separate from the other builds. But if they want to look at the history, they can easily do that. It would take making a post and editing the big post each time but it would save people scrolling past release notes to discuss a single build. We may want to turn off comments for the archive to steer conversation toward current stuff and make it easier to monitor but it’s not necessary.
