✅ What to do first

1. Read the official release notes (linked in “What breaks”).
2. Back up config and data (snapshot the VM/volume if you can).
3. Note the version you are on now, so you can roll back.
4. Update, then check logs and core functions before walking away.

↩️ How to roll back

Docker: snapshot/back up the data volumes first, then if needed change the tag back, e.g. image: ghcr.io/esphome/esphome:<previous tag>, and run docker compose up -d. Tag format varies by image (some drop the “v”), so check the registry’s tag list.
