When we rewrote Flake8 for 3.0, we unintentionally stopped forcibly excluding some patterns regardless of what the user specified. This note is added after the fact to make it easier for users to determine the cause of any backwards incompatibility they might notice. Closes #250

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.
|
|
|
|
- Stop forcibly re-adding ``.tox``, ``.eggs``, and ``*.eggs`` to
|
|
``--exclude``. Flake8 2.x started always appending those three patterns
|
|
to any exclude list (including the default and any user supplied list).
|
|
Flake8 3 has stopped adding these in, so you may see errors when upgrading
|
|
due to these patterns no longer being forcibly excluded by default if you
|
|
have your own exclude patterns specified.
|
|
|
|
To fix this, add the appropriate patterns to your exclude patterns list.
