2.5.1 - 2015-12-08
------------------

- **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`_)

2.4.0 - 2015-03-07
------------------

- **Bug** Print filenames when using multiprocessing and ``-q`` option.
  (`GitLab#31`_)

  - ``mccabe < 0.4``

  - ``pyflakes < 0.9``

  See also `GitLab#32`_

- **Bug** Files excluded in a config file were not being excluded when flake8
  was run from a git hook. (`GitHub#2`_)

- **Improvement** Print warnings for users who are providing mutually
  exclusive options to flake8. (`GitLab#8`_, `GitLab!18`_)

- **Feature** Allow git hook configuration to live in ``.git/config``.
  See the updated `VCS hooks docs`_ for more details. (`GitLab!20`_)

2.2.4 - 2014-10-09
------------------

- Fix bugs triggered by turning multiprocessing on by default (again)

  Multiprocessing is forcibly disabled in the following cases:

  - Passing something in via stdin

  - Analyzing a diff

  - Using windows

- Fix --install-hook when there are no config files present for pep8 or
  flake8.
