This is a big release, the first after the Git migration has really kicked in! And so, here's what it brings us:

- twist, a new command line tool for running Twisted plugins, similar to twistd but with a simpler, cleaner interface.

- A new interface for Protocols, IHandshakeListener, which tells Twisted to tell the Protocol when the TLS handshake has been completed.

- async/await support for Deferreds, allowing you to write Python 3.5+ coroutines using Twisted

- Trial can be invoked with "python -m twisted.trial".

- 35+ more modules ported to Python 3, and many many cleanups on the way to Python 3 on Windows support.

- 240+ closed tickets overall.

For more information, check the NEWS file (link provided below).

As usual, it's available for download -- go here (https://twistedmatrix.com/Releases/pre/16.4.0pre1/) to get the prerelease tarballs and the full NEWS file. If you want to install it right away, run:

   pip install https://twistedmatrix.com/Releases/pre/16.4.0pre1/Twisted-16.4.0rc1.tar.bz2

Please let me know if you have any issues, as well as if you don't! If everything works well, that's a good thing for me to know :)

Twisted Regards,
