✅ 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 to 2026.10.2

Restore the automatic pre-update backup (Settings → System → Backups), or on HA OS run ha core update --version 2026.10.2. In Docker, pin the previous image tag.
