 * <p>Features are classified by their capabilities. Each variant of a feature provides at least
 * the same set of capabilities as the feature itself. Since all variants of a feature are derived
 * from the same sources, they all expose the same API or "content" and thus provide the same
 * capabilities. Some variants may expose additional capabilities than those of its owning feature,
 * for example with fat jars.</p>

  **Updated** default value of the feature flag `VERIFY_CERT_AT_CLIENT` to true.
  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`
