You can now specify whether a TLS certificate was signed by a trusted certificate authority using the new `allow_untrusted_root` attribute. This enhancement to the [TLS certificate endpoints](https://www.fastly.com/documentation/reference/api/tls/custom-certs/certificates/) provides greater flexibility when working with self-signed certificates or certificates from non-standard certificatation authorities.
