 API changes
 #############
-* The :class:`~windpowerlib.wind_turbine.WindTurbine` API has been revised. Main changes are that the parameters `fetch_curve` and `data_source` have been removed.
-These parameters were formerly used to specify whether the power or power coefficient curve should be retrieved and the source to retrieve them from.
-Now per default the power curve and/or power coefficient curve are tried to be retrieved from the oedb turbine library that is provided along with the windpowerlib
-and holds turbine data for a large set of wind turbines. Further important changes are the renaming of the parameter `name` to `turbine_type` and the removal
-of the `coordinates`.
-See the :class:`~windpowerlib.wind_turbine.WindTurbine` docstring and `Initialize wind turbine` in the :ref:`examples_section_label` section for more information.
-(`PR 62 <https://github.com/wind-python/windpowerlib/pull/62>`)
-* The :class:`~windpowerlib.wind_farm.WindFarm` API has been revised. The `wind_turbine_fleet` parameter can now be provided as a pandas DataFrame
-(`PR 63 <https://github.com/wind-python/windpowerlib/pull/63>`_) or as a list using the :func:`~windpowerlib.wind_turbine.WindTurbine.to_group` method
-(`PR 68 <https://github.com/wind-python/windpowerlib/pull/68>`_. Furthermore, the option to specify the wind turbine fleet using the total installed capacity
-of each turbine type has been added. See the :class:`~windpowerlib.wind_farm.WindFarm` docstring and `Initialize wind farm` in the :ref:`examples_section_label` section for more information.

 * get_installed_power() methods in :class:`~windpowerlib.wind_farm.WindFarm` and  :class:`~windpowerlib.wind_turbine_cluster.WindTurbineCluster` were removed. Installed power is instead now directly calculated inside the nominal_power getter.
 * Removed unnecessary `wake_losses_model` parameter in :py:func:`~.power_curves.wake_losses_to_power_curve`. Whether a constant wind farm efficiency or a wind farm efficiency curve is used is decided by the type of the wind farm efficiency.
 * Combined options 'constant_efficiency' and 'power_efficiency_curve' of `wake_losses_model` parameter in :py:func:`~.turbine_cluster_modelchain.TurbineClusterModelChain` to 'wind_farm_efficiency'. Therefore, default value of `wake_losses_model` in :py:func:`~.wind_farm.WindFarm.assign_power_curve` and :py:func:`~.wind_turbine_cluster.WindTurbineCluster.assign_power_curve` changed to 'wind_farm_efficiency'.
