+Specifying which TLS versions to use
+------------------------------------
+
+The desired TLS versions to use during the connection van be specified while getting the session with the use of ``tls-versions`` option and in addition the TLS ciphers can also be specified with the ``tls-ciphersuites`` option. 
+
+.. code-block:: python
+
+   session = mysqlx.get_session('mysqlx://root:@127.0.0.1:33060?tls-versions=[TLSv1.1,TLSv1.2]&tls-ciphersuites=[DHE-RSA-AES256-SHA]&ssl-mode=required')

+   print("Mysqlx_ssl_cipher: {}".format(res[0].get_string('Value')))
+   session.close()
+
+From the given list of TLS versions, the highest supported version will be selected for the connection, given as result:
+
+    Mysqlx_ssl_version: TLSv1.2
+
+    Mysqlx_ssl_cipher: DHE-RSA-AES256-SHA
