Galera Cluster and SSL encryption

Is Galera Cluster really still using old fashioned SSL encryption instead of TLS as some slides in the web say?

Taxonomy upgrade extras: 

Group communication and IST use SSLv23 mode, which according to documentation in uses TLS unless cipher suite (specified in socket.ssl_cipher_list) contains SSLv2 cipher suite. Default cipher suite AES128-SHA is extension to TLSv1 (, so by default Galera is using TLS for encryption.
