`GitLab!424`_, `GitLab#632`_)
Deprecations

- Add deprecation message for vcs hooks (See also `GitLab!420`_,
`GitLab#568`_)
3.8.0a2 -- 2020-04-24
---------------------
You can view the `3.8.0 milestone`_ on GitLab for more details.
Bugs Fixed
~~~~~~~~~~
- Fix ``type="str"`` optparse options (See also `GitLab!419`_)
3.8.0a1 -- 2020-04-24
---------------------
You can view the `3.8.0 milestone`_ on GitLab for more details.
New Dependency Information
~~~~~~~~~~~~~~~~~~~~~~~~~~
- Remove dependency on ``entrypoints`` and add dependency on
``importlib-metadata`` (only for ``python<3.8``) (See also `GitLab!388`_,
`GitLab#569`_)
- Pyflakes has been updated to >= 2.2.0, < 2.3.0 (See also `GitLab!417`_)
- 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`_, `GitLab#535`_)
- Move argument parsing from ``optparse`` to ``argparse`` (See also
`GitLab!341`_
- Group plugin options in ``--help`` (See also `GitLab!342`_, `GitLab#565`_)
- Remove parsing of ``verbose`` from configuration files as it was not
consistently applied (See also `GitLab!360`_, `GitLab#439`_)
- 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`_, `GitLab#590`_)
- Ensure that a missing file produces a ``E902`` error (See also `GitLab!404`_,
`GitLab#600`_)
- ``# noqa`` comments now apply to all of the lines in an explicit ``\``
continuation or in a line continued by a multi-line string (See also
`GitLab!413`_, `GitLab#375`_)
Bugs Fixed
~~~~~~~~~~
- Fix ``--exclude=./t.py`` to only match ``t.py`` at the top level (See also
`GitLab!311`_, `GitLab#382`_)
- Fix ``--show-source`` when a file is indented with tabs (See also
`GitLab!339`_, `GitLab#563`_)
- Fix crash when ``--max-line-length`` is given a non-integer (See also
`GitLab!341`_, `GitLab#541`_)
- Prevent flip-flopping of ``indent_char`` causing extra ``E101`` errors (See
also `GitLab!357`_, `pycodestyle#886`_)
- Only enable multiprocessing when the method is ``fork`` fixing issues
on macos with python3.8+ (See also `GitLab!366`_, `GitLab#587`_) (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`_, `GitLab#552`_)
- 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`_, `GitLab#270`_)
Deprecations
~~~~~~~~~~~~
- ``python setup.py flake8`` (setuptools integration) is now deprecated and
will be removed in a future version (See also `GitLab!330`_, `GitLab#544`_)
- ``type='string'`` (optparse) types are deprecated, use
``type=callable`` (argparse) instead. Support for ``type='string'`` will
be removed in a future version (See also `GitLab!341`_)
- ``%default`` in plugin option help text is deprecated, use ``%(default)s``
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
(See also `GitLab!341`_)
