On behalf of Twisted Matrix Laboratories, I'm honoured to announce the release of Twisted 18.4.0! The highlights of the release are: - The dropping of Python 3.3 support. - Python 3 fixes (notably to trial -j, asyncioreactor, conch, and mail) - Python 3 TCP speed improvements (less copying when sending data) - Better TLS curve selection support for both old and new OpenSSLs - IPv6 fixes for WSGIResource - 60+ closed tickets with many fixed bugs! For more information, check the NEWS file (link provided below). You can find the downloads at <https://pypi.python.org/pypi/Twisted> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads>). The NEWS file is also available at <https://github.com/twisted/twisted/blob/twisted-18.4.0/NEWS.rst>. Many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code as well as documentation, and all the people building great things with Twisted!
