* B906: Add ``visit_Bytes``, ``visit_Num`` and ``visit_Str`` to the list of ``visit_*``
functions that are ignored by the B906 check. The ``ast.Bytes``, ``ast.Num`` and
``ast.Str`` nodes are all deprecated, but may still be used by some codebases in
order to maintain backwards compatibility with Python 3.7.
* B016: Warn when raising f-strings.
* Add B028: Check for an explicit stacklevel keyword argument on the warn method from the warnings module.
* Add B029: Check when trying to use ``except`` with an empty tuple i.e. ``except: ()``.
* Add B032: Check for possible unintentional type annotations instead of assignments.
