- update to 1.12.0:
* Provided that you only want to support Python 3.7, when deriving from
a base class which has a decorator applied to it, you no longer need
to access the true type of the base class using ``__wrapped__`` in
the inherited class list of the derived class.
* When using the ``synchronized`` decorator on instance methods of a
class, if the class declared special methods to override the result for
when the class instance was tested as a boolean so that it returned
``False`` all the time, the synchronized method would fail when called.
* When using an adapter function to change the signature of the decorated
function, ``inspect.signature()`` was returning the wrong signature
when an instance method was inspected by accessing the method via the
class type.
