 Breaking changes
 ~~~~~~~~~~~~~~~~
+* Moved functions related to inverters from ``pvsystem.py`` to ``inverter.py``.
+  Functions are renamed to follow a more consistent pattern, as follows (:pull:`886`, :pull:`1136`):
+
+    - ``pvlib.pvsystem.snlinverter`` is now :py:func:`pvlib.inverter.sandia`
+    - ``pvlib.pvsystem.pvwatts_ac`` is now :py:func:`pvlib.inverter.pvwatts`
+    - ``pvlib.pvsystem.adrinverter`` is now :py:func:`pvlib.inverter.adr`
+
+* Argument ``ac_model`` for :py:class:`pvlib.modelchain.ModelChain` now accepts
+  ``'sandia'``, ``'pvwatts'`` and ``'adr'`` for the inverter models. (:pull:`886`, :pull:`1136`)
+
+* Calling :py:meth:`pvlib.pvsystem.PVSystem.sapm_celltemp` without setting
+  ``PVSystem.temperature_model_parameters``,
+  or a valid combination of ``PVsystem.module_type`` and ``PVsystem.racking_model``, will
+  now raise an exception. (:issue:`1030`, :pull:`1033`, :pull:`1136`)
+
+* Deprecated arbitrary keyword arguments for
+  :py:class:`pvlib.location.Location`, :py:class:`pvlib.pvsystem.PVSystem`,
+  :py:class:`pvlib.tracking.SingleAxisTracker`, and
+  :py:class:`pvlib.modelchain.ModelChain`. Supplying arbitrary keyword
+  to these objects result in TypeErrors in v0.9. (:issue:`1029`, :pull:`1053`, :pull:`1136`)
+
+* ``pvlib.pvsystem.LocalizedPVSystem`` and ``pvlib.pvsystem.LocalizedSingleAxisTracker``
+  have been removed. Use
+  :py:class:`pvlib.location.Location`, :py:class:`pvlib.pvsystem.PVSystem`,
+  :py:class:`pvlib.tracking.SingleAxisTracker`, and
+  :py:class:`pvlib.modelchain.ModelChain` instead.
+  (:issue:`1029`, :pull:`1034`, :pull:`1053`, :pull:`1136`)
+
+* ``irradiance.liujordan`` and ``ForecastModel.cloud_cover_to_irradiance_liujordan``
+  have been removed. (:pull:`1136`)
