- Ability to specify supported TLS protocol versions within ``tls``
clauses (e.g. ``protocols { TLSv1.2; TLSv1.3; };``). :gl:`#2795`
+- New options within ``tls`` clauses were implemented, namely:
+ - ``dhparam-file "<path_to_file>";`` to specify Diffie-Hellman parameters;
+ - ``ciphers "<cipher_list>";`` to specify OpenSSL ciphers list;
+ - ``prefer-server-ciphers yes|no;`` to assert server or client ciphers preference;
+ - ``session-tickets yes|no;`` to explicitly enable or disable stateless TLS session tickets (see RFC5077).
+ These options allow finer control over TLS protocol features and make it
+ possible to achieve perfect forward secrecy for DNS-over-TLS and
+ DNS-over-HTTPS. :gl:`#2796`
