How to get notified when preview image becomes release?

I recently switched from linuxserver/sonarr:latest to linuxserver/sonarr:preview on account of the UI being more in line with radarr/lidarr. This upgraded the db so downgrade in case of issues is not an option, which makes me a bit wary of the preview image. There’s nothing wrong with it at the moment it’s just you never know when will an alpha break.

How would I go about getting notified when a preview version of sonarr (with v3 of ui) will become a release version of sonarr (currently v2 ui)? Then I could flip the preview back to latest in my docker-compose.yml without messing up the db.

Many thanks for any ideas!

You will likely get a deprecation notice in your container log during start
