Version 2.0.0 adds scoped Security Hub corrective remediation routes and the monitoring v3 delivery failure contract.
Consumers enabling Security Hub alerting must set security_hub.delivery_failure with an owner, a separate same-account and Region escalation SNS topic ARN, and an HTTPS runbook URL.
Update Security Hub alerting configurations with the required security_hub.delivery_failure owner, same-account and Region escalation SNS topic ARN, and HTTPS runbook URL before deploying version 2.0.0.
Validate the security_hub.delivery_failure configuration for Security Hub alerting, including its owner, escalation SNS topic ARN, and HTTPS runbook URL, before deployment.
