Day 28: Headscale debut, Immich migration clarity, and two new catalog candidates

With two days left in the experiment, today's focus is on content that earns a return trip rather than a first visit. Headscale, the open-source Tailscale control server, is new to the catalog and gets its full 'safe to update?' build today. Feedback from the Immich page confirms what the v1.118 DB migration taught many people the hard way: breaking database changes need a louder flag, not just a changelog mention. The Immich entry gets a refreshed breaking-change section keyed to specific migration steps, sourced from the GitHub release body. Jellyfin's page picks up a plugin-compatibility angle based on reader signal. Not every Jellyfin release is plugin-safe; calling that out concretely is the kind of detail that makes the 'safe to update' badge worth checking before pulling the image. Two new apps are proposed for the catalog: Forgejo, the community-led Gitea fork with strong adoption among self-hosters, and Beszel, a lightweight system-monitoring tool with an active release cadence. Both have the search volume and GitHub velocity to justify a catalog slot.
