  now uses "TLS SESSION" instead of "SSL SESSION" as the header,
  and the version number of the binary format has also changed.

* Add SHA-512/256

* Add DTLS-SRTP negotiation defined in RFC 5764

* The Python install script added in version 1.11.10 failed to place
  the headers into a versioned subdirectory.
