+PEP 692: Using ``TypedDict`` for more precise ``**kwargs`` typing
+-----------------------------------------------------------------
+
+Typing ``**kwargs`` in a function signature as introduced by :pep:`484` allowed
+for valid annotations only in cases where all of the ``**kwargs`` were of the
+same type.
+
+This PEP specifies a more precise way of typing ``**kwargs`` by relying on
+typed dictionaries::
+
+   from typing import TypedDict, Unpack
+
+   class Movie(TypedDict):
+     name: str
+     year: int
+
+   def foo(**kwargs: Unpack[Movie]): ...
+
+See :pep:`692` for more details.
