Twisted 16.0 Released

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.0! Twisted 16.0 brings some important changes, and some nice-to-haves as well. The major things are: - TLS endpoints have arrived! They're like the old `ssl:` endpoints, but support faster IPv4/IPv6
