  ``protected-access`` message emission for single underscore prefixed attribute in special methods.

  Close 3120

  Close 3811

* ``inconsistent-return-statements`` message is now emitted if one of ``try/except`` statement
  is not returning explicitly while the other do.

  Closes 3468

* Fix ``useless-super-delegation`` false positive when default keyword argument is a dictionnary.

  Close 3773

* Fix a crash when a specified config file does not exist

* Add support to ``ignored-argument-names`` in DocstringParameterChecker and adds `useless-param-doc` and `useless-type-doc` messages.

* `len-as-conditions` is now triggered only for classes that are inheriting directly from list, dict, or set and not implementing the `__bool__` function, or from generators like range or list/dict/set comprehension. This should reduce the false positives for other classes, like pandas&#39;s DataFrame or numpy&#39;s Array.

  Close 1879

* Fixes duplicate-errors not working with -j2+

  Close 3314

  Close 3407

* Changed setup.py to work with [distlib](https://pypi.org/project/distlib)

  Close 3555

* New check: ``consider-using-generator``

  This check warns when a comprehension is used inside an `any` or `all` function,
  since it is unnecessary and should be replaced by a generator instead.
  Using a generator would be less code and way faster.

  Close 3165

* Add Github Actions to replace Travis and AppVeyor in the future
