Hi everyone! It's been brought to my attention that I misworded something in the release notes and it slipped through the cracks. In the NEWS I said:

This is the last Twisted release where Python 2.6 is supported, on any platform.

However, I meant that this is the first Twisted release to drop 2.6 support wholesale, preventing import on this platform. Twisted 15.4 will still operate, so if you have Python 2.6 deployment requirements, bracket the maximum to 15.4 on that platform by using an if statement in your setup.py, and `Twisted >=*minreq*,<=15.4; python_version < '2.7'` under requires_dist in your setup.cfg, where minreq is the minimum required Twisted. Sorry for the inconvenience! - Amber "HawkOwl" Brown Twisted Release Manager
