5683,Raise the minimum required version of zope.interface to 3.6.0,itamar,itamar,"As mentioned in http://pypi.python.org/pypi/zope.interface/4.0.0, newer versions of zope.interface give deprecation warning for `implements()`, which is used widely by Twisted. This was done in order to support Python 3; the newer version is a class decorator.

As part of Python 3 support we should probably switch to the new style. It was added in zope.interface 3.6, in 2010, so switching completely doesn't seem like an issue: http://pypi.python.org/pypi/zope.interface/3.6.0#id5

Using class decorators shouldn't be a problem post-12.1, since we'll have dropped Python 2.5 support by then (#5553).

We should ensure Twisted mentions it requires zope.interface 3.6 in the appropriate places (import time, dependency documentation).",defect,closed,normal,Python-3.x,core,fixed,,vperic thijs,branches/zope-requirement-5683,vperic,
