+- update to version 0.18.1:

+2021.5.0 ``dask.distributed`` release. It also includes a new
+``drop_duplicates`` method, some documentation improvements, the beginnings of
+ - our internal Index refactoring, and some bug fixes.:
+ - Thank you to all 16 contributors!:
+ - Anderson Banihirwe, Andrew, Benoit Bovy, Brewster Malevich, Giacomo Caria,:
+ - Illviljan, James Bourbeau, Keewis, Maximilian Roos, Ravin Kumar, Stephan Hoyer,:

+  - Allow passing ``combine_attrs`` strategy names to the ``keep_attrs`` parameter of
+    :py:func:`apply_ufunc` (:pull:`5041`)
+    By `Justus Magin <https://github.com/keewis>`_.
+  - :py:meth:`Dataset.interp` now allows interpolation with non-numerical datatypes,
+    such as booleans, instead of dropping them. (:issue:`4761` :pull:`5008`).
+    By `Jimmy Westling <https://github.com/illviljan>`_.

+    ``Dataset.xindexes`` / ``DataArray.xindexes`` properties. Also rename
+    ``PandasIndexAdapter`` to ``PandasIndex``, which now inherits from
+    ``xarray.Index`` (:pull:`5102`).
+    By `Benoit Bovy <https://github.com/benbovy>`_.
