New Dependency Information
~~~~~~~~~~~~~~~~~~~~~~~~~~

`GitLab569`_)

- pycodestyle has been updated to >= 2.6.0a1, < 2.7.0 (See also `GitLab!418`_)

Features
~~~~~~~~

- Add ``--extend-exclude`` option to add to ``--exclude`` without overwriting
(See also `GitLab!315`_, `GitLab535`_)

- Move argument parsing from ``optparse`` to ``argparse`` (See also
`GitLab!341`_

- Group plugin options in ``--help`` (See also `GitLab!342`_, `GitLab565`_)

- Remove parsing of ``output_file`` from configuration files as it was not
consistently applied (See also `GitLab!361`_)

- Resolve configuration files relative to ``cwd`` instead of common prefix of
passed filenames.  You may need to change ``flake8 subproject`` to
``cd subproject && flake8 .`` (See also `GitLab!363`_)

- Officially support python3.8 (See also `GitLab!377`_)

- ``--disable-noqa`` now also disables `` flake8: noqa`` (See also
`GitLab!380`_, `GitLab590`_)

- Ensure that a missing file produces a ``E902`` error (See also `GitLab!404`_,
`GitLab600`_)

continuation or in a line continued by a multi-line string (See also

Bugs Fixed
~~~~~~~~~~

- Fix ``--exclude=./t.py`` to only match ``t.py`` at the top level (See also
`GitLab!311`_, `GitLab382`_)

- Fix ``--show-source`` when a file is indented with tabs (See also
`GitLab!339`_, `GitLab563`_)

- Fix crash when ``--max-line-length`` is given a non-integer (See also
`GitLab!341`_, `GitLab541`_)

- Prevent flip-flopping of ``indent_char`` causing extra ``E101`` errors (See
also `GitLab!357`_, `pycodestyle886`_)

- Only enable multiprocessing when the method is ``fork`` fixing issues
on macos with python3.8+ (See also `GitLab!366`_, `GitLab587`_) (note: this
fix also landed in 3.7.9)

- ``noqa`` is now only handled by flake8 fixing specific-noqa.  Plugins
requesting this parameter will always receive ``False`` (See also
`GitLab!331`_, `GitLab552`_)

- Fix duplicate loading of plugins when invoked via ``python -m flake8`` (See
also `GitLab!388`_)

- Fix early exit when ``--exit-zero`` and ``--diff`` are provided and the diff
is empty (See also `GitLab!391`_)

- Consistently split lines when ``\f`` is present when reading from stdin (See
also `GitLab!406`_, `GitLab270`_)

Deprecations

will be removed in a future version (See also `GitLab!330`_, `GitLab544`_)

``type=callable`` (argparse) instead.  Support for ``type='string'`` will
be removed in a future version (See also `GitLab!341`_)

instead.  Support for ``%default`` will be removed in a future version (See
also `GitLab!341`_)

- optparse-style ``action='callback'`` setting for options is deprecated, use
argparse action classes instead.  This will be removed in a future version
