✅ 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 v1.104.4

Reinstall the previous package version from your distro repo (e.g. apt install tailscale=v1.104.4) or pin the previous container tag.
