This is critical because it allows this workflow to finish immediately without waiting for the Docker update to complete, preventing a crash when the docker instance is stopped.\n* **Log File:** Any output or errors from the update process are saved to a file named `update.log` in your n8n Docker directory on the server. **Check this file if you encounter issues after an update.**"
