 Breaking changes
 ~~~~~~~~~~~~~~~~
 
+- Minimum supported versions for the following packages have changed: ``dask >=2.9``,
+  ``distributed>=2.9``.
+  By `Deepak Cherian <https://github.com/dcherian>`_
 - ``groupby`` operations will restore coord dimension order. Pass ``restore_coord_dims=False``
   to revert to previous behavior.
 - :meth:`DataArray.transpose` will now transpose coordinates by default.
