 * Edited docstrings for :py:func:`~pvlib.pvsystem.dc_ohms_from_percent` and
   :py:func:`~pvlib.pvsystem.dc_ohmic_losses` for clarity. (:issue:`1601`, :pull:`2229`)
+* Added 'freestanding' and 'insulated' `racking_model` options for cell
+  temperature calculation in :py:class:`~pvlib.pvsystem.PVSystem`
+  :py:class:`~pvlib.pvsystem.SingleAxisTrackerMount`, and
+  :py:class:`~pvlib.pvsystem.FixedMount` docstrings. Various formatting edits
+  for clarity. (:issue:`1942`, :pull:`2232`)
 * Added a new citation style guide (:ref:`references`) to the contributing
   page. (:issue:`2202`, :pull:`2226`)
 * Updated :py:func:`~pvlib.irradiance.reindl` to include definitions of terms
