+* The function and methods named ``create_task`` have received a new
+  ``**kwargs`` argument that is passed through to the task constructor.
+  This change was accidentally added in 3.13.3,
+  and broke the API contract for custom task factories.
+  Several third-party task factories implemented workarounds for this.
+  In 3.13.4 and later releases the old factory contract is honored
+  once again (until 3.14).
+  To keep the workarounds working, the extra ``**kwargs`` argument still
+  allows passing additional keyword arguments to :class:`~asyncio.Task`
+  and to custom task factories.
+
+  This affects the following function and methods:
+  :meth:`asyncio.create_task`,
+  :meth:`asyncio.loop.create_task`,
+  :meth:`asyncio.TaskGroup.create_task`.

+* The function and methods named :func:`!create_task` now take an arbitrary

+  :class:`~asyncio.Task` constructor or the custom task factory.
+  (See :meth:`~asyncio.loop.set_task_factory` for details.)
+  The ``name`` and ``context`` keyword arguments are no longer special;
