=head1 DESCRIPTION
-The functionality provided by the servername callback is superseded by
-the early callback, which can be set using SSL_CTX_set_early_cb().
+The functionality provided by the servername callback is superseded by the
+ClientHello callback, which can be set using SSL_CTX_set_client_hello_cb().
The servername callback is retained for historical compatibility.
SSL_CTX_set_tlsext_servername_callback() sets the application callback B<cb>
=head1 NOTES
Several callbacks are executed during ClientHello processing, including
-the early, ALPN, and servername callbacks. The early callback is executed
-first, then the servername callback, followed by the ALPN callback.
+the ClientHello, ALPN, and servername callbacks. The ClientHello callback is
+executed first, then the servername callback, followed by the ALPN callback.
The SSL_set_tlsext_host_name() function should only be called on SSL objects
that will act as clients; otherwise the configured B<name> will be ignored.
