Version 0.11.0 aka The New Violation Codes

We had a really big problem: all violations inside best_practices
was messed up together with no clear structure.

We had to fix it before it is too late.
So, we broke existing error codes.
And now we can promise not to do it ever again.

We also have this nice migration guide
for you to rename your violations with a script.

Features

• Breaking: replaces Z error code to WPS code
• Breaking: creates new violation group refactoring.py
• Breaking: creates new violation group oop.py
• Breaking: moving a lot of violations
  from best_practices to refactoring, oop, and consistency
• Adds new wemake formatter (using it now by default)

Bugfixes

• Fixes error message of OverusedStringViolation for empty strings
• Now does not count string annotations as strings for OverusedStringViolation
• Fixes InconsistentReturnVariableViolation was raised twice

Misc

• Adds migration guide to 0.11
• Improves legacy guide
• Adds --show-source to the default recommended configuration
• Adds better docs about auto-formatters
• Adds autopep8 to CI to make sure that wps is compatible with it
• Ensures that --diff mode works for flake8
• Renames Incorrect to Wrong where possible
• Renames IncorrectlyNestedTernaryViolation to NestedTernaryViolation
• Renames IncorectLoopIterTypeViolation to WrongLoopIterTypeViolation

Version 0.10.0 aka The Great Compare

This release is mostly targeted at writing better compares and conditions.
We introduce a lot of new rules related to this topic improving:
consistency, complexity, and general feel from your code.

In this release we have ported a lot of existing pylint rules,
big cudos to the developers of this wonderful tool.

  instead of isinstance(some, A) or isinstance(some, B)

  to merge a != b and a != c into a not in {b, c}
