+  **DEPRECATED** The ``--remote-cert-tls`` option should be used instead.
+  The option is still available since it can't be silently ignored and needs
+  updates to certificates and configs on both sides of the connection.
+  However it should not be used for new clients or servers. It depends on the

---ns-cert-type
-  Removed in OpenVPN 2.5.  The ``nsCertType`` field is no longer supported
-  in recent SSL/TLS libraries.  If your certificates does not include *key
-  usage* and *extended key usage* fields, they must be upgraded and the
-  ``--remote-cert-tls`` option should be used instead.

 --prng
   Removed in OpenVPN 2.6.  We now always use the PRNG of the SSL library.
