- Remove dependency on ``entrypoints`` and add dependency on

- pycodestyle has been updated to >= 2.6.0a1, < 2.7.0 (See also :issue:`983`)

Features
~~~~~~~~

- Add ``--extend-exclude`` option to add to ``--exclude`` without overwriting
(See also :issue:`1211`, :issue:`1091`)

- Move argument parsing from ``optparse`` to ``argparse`` (See also
:issue:`939`

consistently applied (See also :issue:`1245`, :issue:`245`)

- Remove parsing of ``output_file`` from configuration files as it was not
consistently applied (See also :issue:`1246`)

- 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 :issue:`952`)

- Officially support python3.8 (See also :issue:`963`)

- ``--disable-noqa`` now also disables `` flake8: noqa`` (See also
:issue:`1296`, :issue:`318`)

- Ensure that a missing file produces a ``E902`` error (See also :issue:`1262`,

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
:issue:`1208`, :issue:`628`)

- Fix ``--show-source`` when a file is indented with tabs (See also
:issue:`1218`, :issue:`719`)

- Fix crash when ``--max-line-length`` is given a non-integer (See also
:issue:`939`, :issue:`704`)

- Prevent flip-flopping of ``indent_char`` causing extra ``E101`` errors (See
also :issue:`949`, `pycodestyle886`_)

- Only enable multiprocessing when the method is ``fork`` fixing issues
on macos with python3.8+ (See also :issue:`955`, :issue:`315`) (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
:issue:`1214`, :issue:`1104`)

- Fix duplicate loading of plugins when invoked via ``python -m flake8`` (See
also :issue:`1297`)

is empty (See also :issue:`970`)

also :issue:`976`, :issue:`202`)

- ``python setup.py flake8`` (setuptools integration) is now deprecated and
will be removed in a future version (See also :issue:`935`, :issue:`1098`)

``type=callable`` (argparse) instead.  Support for ``type='string'`` will
be removed in a future version (See also :issue:`939`)

instead.  Support for ``%default`` will be removed in a future version (See
also :issue:`939`)

- optparse-style ``action='callback'`` setting for options is deprecated, use
argparse action classes instead.  This will be removed in a future version
(See also :issue:`939`)
