    Description

      According to RFC 4346 Section 7.4.13 "Server Hello" and RFC 5246 Appendix E the Server Hello packet needs to specify the highest supported TLS version, but not higher than what client requests.

      YaSSL's highest supported version is TLSv1.1 (=3.2) - if the client requests a higher version, it needs to be downgraded in Server Hello packet to TLSv1.1 instead of interrupting the handshake and closing the connection.
