+* A `pyhf.default_backend` has been added that is configurable through a
+  ``default`` kwarg in :func:`pyhf.set_backend`.
+  (PR :pr:`1646`)
 * All backends are now fully compatible and tested with
   `Python 3.10 <https://peps.python.org/pep-0310/>`_.

+* A ``pyhf.default_backend`` has been added that is configurable through a
