Twisted 19.7.0 Released

On behalf of Twisted Matrix Laboratories and our long-suffering release manager Amber Brown, I am honored to announce¹ the release of Twisted 19.7.0!

The highlights of this release include:

• A full description on the PyPI page!  Check it out here: https://pypi.org/project/Twisted/19.7.0/ (and compare to the slightly sad previous version, here: https://pypi.org/project/Twisted/19.2.1/)
• twisted.test.proto_helpers has been renamed to "twisted.internet.testing"
• This removes the gross special-case carve-out where it was the only "public" API in a test module, and now the rule is that all test modules are private once again.
• Conch's SSH server now supports hmac-sha2-512.
• The XMPP server in Twisted Words will now validate certificates!
• This is a very important security fix for any twisted.words / XMPP users. (See https://twistedmatrix.com/trac/ticket/9561)
• A nasty data-corruption bug in the IOCP reactor was fixed. If you're doing high-volume I/O on Windows you'll want to upgrade!
• Twisted Web no longer gives clients a traceback by default, both when you instantiate Site and when you use twist web on the command line.  You can turn this behavior back on for local development with twist web --display-tracebacks.
• Several bugfixes and documentation fixes resolving bytes/unicode type confusion in twisted.web.
• Python 3.4 is no longer supported.

pip install -U twisted[tls] and enjoy all these enhancements today!

Thanks for using Twisted,

-glyph
