  This means server certificates will be automatically verified using the OS CA certificates when not using a DestinationRule caCertificates field.
  If undesired please use the new `compatibilityVersion` feature to fallback to old behavior, or `insecureSkipVerify`
  field in DestinationRule to skip the verification.
upgradeNotes:
- title: Default value of the feature flag `VERIFY_CERT_AT_CLIENT` is set to true
