+|release v0.7.2|_
+=================
+
+This is a patch release from ``v0.7.1`` → ``v0.7.2``.
+
+Important Notes
+---------------
+
+* ``pyhf`` became a `NumFOCUS Affiliated Project
+  <https://numfocus.org/sponsored-projects/affiliated-projects>`__ on
+  2022-12-19. |NumFOCUS Affiliated Project|
+  ``v0.7.1`` is the first release to appear in a NumFOCUS Newsletter and
+  ``v0.7.2`` is the first release to appear as part of the Affiliated Projects
+  page.
+  (PR :pr:`2179`)
+
+Fixes
+-----
+
+* If a multiple component parameter of interest is used raise
+  :class:`~pyhf.exceptions.InvalidModel`.
+  This guards against modifiers like :class:`~pyhf.modifiers.shapefactor`,
+  :class:`~pyhf.modifiers.shapesys`, and :class:`~pyhf.modifiers.staterror`
+  from being used as POIs.
+  (PR :pr:`2197`)
+* Use :data:`typing.TYPE_CHECKING` guard to avoid causing a
+  :class:`ModuleNotFoundError` when the version of NumPy installed is older
+  than ``v1.21.0``, which is the first NumPy release to include
+  :mod:`numpy.typing`.
+  (PR :pr:`2208`)
