Flake8 takes the somewhat controversial stance of being stable rather than being able to handle all the things in one version. The 2.4.x series of Flake8 restricts itself to known working versions of pep8 and pyflakes (neither of which can handle 3.5 or the new syntax added in it). Flake8 2.5.0 will raise the cap on pyflakes to allow this to work but there is no current release of pep8 that is compatible with the version specifier that Flake8 carries for stability and will also work with Python 3.5.0 (note, you will merely see a Deprecation Warning due to currently released versions of pep8 using inspect.getargspec which is fixed in master). Because of how late in the week it is, I'm going to put off a Flake8 2.5.0 release until Monday so that in the event this causes people's continuous integration to fail, they're not scrambling to do it tomorrow or over the weekend. (See also responsible release practices.)
