3.0.0 -- 2016-07-25
-------------------
- Rewrite our documentation from scratch! (http://flake8.pycqa.org)
- Drop explicit support for Pythons 2.6, 3.2, and 3.3.
- Remove dependence on pep8/pycodestyle for file processing, plugin
dispatching, and more. We now control all of this while keeping backwards
compatibility.
- ``--select`` and ``--ignore`` can now both be specified and try to find the
most specific rule from each. For example, if you do ``--select E --ignore
E123`` then we will report everything that starts with ``E`` except for
``E123``. Previously, you would have had to do ``--ignore E123,F,W`` which
will also still work, but the former should be far more intuitive.
- Add support for in-line ``# noqa`` comments to specify **only** the error
codes to be ignored, e.g., ``# noqa: E123,W503``
- Add entry-point for formatters as well as a base class that new formatters
can inherit from. See the documentation for more details.
- Add detailed verbose output using the standard library logging module.
- Enhance our usage of optparse for plugin developers by adding new parameters
to the ``add_option`` that plugins use to register new options.
- Update ``--install-hook`` to require the name of version control system hook
you wish to install a Flake8.
- Stop checking sub-directories more than once via the setuptools command
- When passing a file on standard-in, allow the caller to specify
``--stdin-display-name`` so the output is properly formatted
- The Git hook now uses ``sys.executable`` to format the shebang line.
This allows Flake8 to install a hook script from a virtualenv that points to
that virtualenv's Flake8 as opposed to a global one (without the virtualenv
being sourced).
- Print results in a deterministic and consistent ordering when used with
multiprocessing
- When using ``--count``, the output is no longer written to stderr.
- AST plugins can either be functions or classes and all plugins can now
register options so long as there are callable attributes named as we
expect.
