Status update for WG tls

The TLS working group met on Tuesday morning. We are continuing progress on TLS 1.3. Main discussion points included a change in the cipher suite model from a monolithic ID approach to a menu based approach. During the Hackathon on Saturday we had 7 different TLS 1.3 implementations achieve interoperability to various degrees. We expect to have a draft (probably -16) that "freezes" the wire format at the end of next month available for broad review by the cryptographic and security modeling communities. We plan on holding working group last call before the next IETF.
