 Breaking Changes
 ~~~~~~~~~~~~~~~~
+* Remove support for the `g_poa_effective` keyword argument in
+  :py:func:`pvlib.pvsystem.pvwatts_dc`. Users must now use
+  `effective_irradiance`. (:issue:`2703`, :pull:`2704`)
 * Change output type of :py:func:`pvlib.irradiance.perez` and
   :py:func:`pvlib.irradiance.perez_driesse` from ``OrderedDict`` to ``dict`` when
   ``return_components=True`` to be consistent with other models.

   Use other diffuse transposition models in :py:mod:`pvlib.irradiance` instead.
