Twisted 15.4 Released

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 15.4, codenamed "Trial By Fire".

Twisted is continuing to forge ahead, with the highlights of this release being:
  • twisted.positioning, the rest of twisted.internet.endpoints, KQueueReactor (for real this time), and twisted.web.proxy/guard have all been ported to Python 3.
  • Trial has been ported to Python 3! This was made possible by a Python Software Foundation grant.
  • Twisted officially supports several more platforms: Py3.4 on FreeBSD, Py2.7/Py3.4 on Fedora 21/22, and Py2.7 on RHEL7.
  • Python 2.6 is no longer supported, and support for Debian 6, and RHEL6 has been removed because of this.
  • Support for the EOL'd platforms of Fedora 17/18/19 has been removed.
  • Twisted has moved to requiring setuptools for installation.
  • twisted.python.failure.Failure's __repr__ now includes the  exception message.
  • 19 tickets in total closed!
You can find the downloads at (or alternatively The NEWS file can be found at

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!

Twisted Regards,

Amber "Hawkie" Brown
