 * Compatibility with xarray >= 2023.09.: The chunked spatial dimension in `aggregate` was raising an error with the new xarray version. This is fixed now.
-* Bug fix: Some wind turbine models did not include a cut-out wind speed, potentially causing overestimated power generation in windy conditions. Cut-out wind speeds were added to the following affected wind turbine models (`#316 <https://github.com/PyPSA/atlite/issues/314>`_):

 * A cutout can now be loaded with setting chunks to ``auto``.
 * The Cutout class has a new function ``area`` which return a DataArray with dimensions (x,y) with the area of each grid cell.
 * The Cutout class has a new function ``layout_from_area_density`` which returns a capacity layout with the capacity per grid cell based on the area density.
