on pep8.

CHANGES
=======
2.x.y - 2015-aa-bb
2.5.1 - 2015-12-15
------------------
- **Bug** Properly look for ``.flake8`` in current working directory
(`GitLab#103`_)
- **Bug** Monkey-patch ``pep8.stdin_get_value`` to cache the actual value in
stdin. This helps plugins relying on the function when run with
multiprocessing. (`GitLab#105`_, `GitLab#107`_)
