-:func:`functools.singledispatch` and :func:`functools.singledispatchmethod`
-now require callables to be correctly annotated if registering without a type explicitly
-specified in the decorator. The first user-specified positional parameter of a callable

+When registering a callable to :func:`functools.singledispatch`
+or :func:`functools.singledispatchmethod` via a type annotation,
+it is now validated that the first proper positional parameter is annotated.
+Before, a callable could be registered based on its return type
 annotation or based on an irrelevant parameter type annotation. Patch by Bartosz Sławecki.
