-API Breaking Changes
-~~~~~~~~~~~~~~~~~~~~
-

-  in ``ivtools.py`` have been renamed (:pull:`708`)
-   - Functions for fitting diode models are now in ``ivtools\sdm.py``
-   - :py:func:`pvlib.ivtools.fit_sdm_cec_sam` is now :py:func:`pvlib.ivtools.sdm.fit_cec_sam`

-
-API Changes with Deprecations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-* Moved functions related to inverters from ``pvsystem.py`` to ``inverter.py``.
-  Functions are renamed to follow a more consistent pattern, as follows (:pull:`886`):
-   - :py:func:`pvlib.pvsystem.snlinverter` is now :py:func:`pvlib.inverter.sandia`
-   - :py:func:`pvlib.pvsystem.pvwatts_ac` is now :py:func:`pvlib.inverter.pvwatts`
-   - :py:func:`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`)
-* :py:class:`pvlib.pvsystem.PVSystem` ``module_type`` and ``racking_model`` now
-  default to ``None``. This continues a deprecation of assuming SAPM values
-  for cell temperature modeling. In this v0.8 release series, 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 cause
-  ``PVSystem.temperature_model_parameters`` to be set to SAPM values for a
-  glass/glass module in open racking and emit a warning. In v0.9, users must
-  provide ``temperature_model_parameters`` or a valid combination of
-  ``module_type`` and ``racking_model``. (:issue:`1030`, :pull:`1033`)
-* 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 will result in TypeErrors in v0.9. (:issue:`1029`, :pull:`1053`)
-* ``pvlib.pvsystem.LocalizedPVSystem`` and ``pvlib.pvsystem.LocalizedSingleAxisTracker``
-  are deprecated and will be removed in 0.9. Use
-  :py:class:`pvlib.location.Location`, :py:class:`pvlib.pvsystem.PVSystem`,
-  :py:class:`pvlib.tracking.SingleAxisTracker`, and

   now recommended to retrieve newer PSM3 data over the older TMY3 data.

 * The tkinter-based file selection dialog has been removed from
   :py:func:`pvlib.iotools.read_tmy2` and :py:func:`pvlib.iotools.read_tmy3`;
   the filepath is now a required parameter. (:pull:`1004`)

   used in pvlib and its output was not directly compatible with any pvlib
   function. See :py:func:`pvlib.iotools.read_tmy2`,
   :py:func:`pvlib.iotools.read_tmy3`, :py:meth:`pvlib.location.Location.from_tmy`, and
