The current github version of CyaSSL and the upcoming release of CyaSSL 3.3 on or about November 10th allows the user to set a minimum version during version downgrade on a single connection attempt:

CyaSSL_SetMinVersion(ssl, CYASSL_TLSV1_1); for example. Previously users would simply end the connection if the resulting version was unsatisfactory, which could be done as early as the certificate handshake message with a callback.

Downgrade for CyaSSL only happens with the v23() methods (CyaSSLv23_client_method() and CyaSSLv23_server_method()), all other methods are version specific. That is,

CyaTLSv1_2_client_method() allows TLS 1.2 connections only.

I hope that helps,
-Todd
