 ### Changes between 3.0 and 3.1 [xx XXX xxxx]
 
+ * The SSL_CTX_set_cipher_list family functions now accept ciphers using their
+   IANA standard names.
+
+   *Erik Lax*
+
  * The PVK key derivation function has been moved from b2i_PVK_bio_ex() into
    the legacy crypto provider as an EVP_KDF. Applications requiring this KDF
    will need to load the legacy crypto provider.

 The cipher list consists of one or more I<cipher strings> separated by colons.
 Commas or spaces are also acceptable separators but colons are normally used.
 
+The cipher string may reference a cipher using its standard name from
+the IANA TLS Cipher Suites Registry
+(L<https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4>).
+
 The actual cipher string can take several different forms.
 
 It can consist of a single cipher suite such as B<RC4-SHA>.
