-v2022.06.0 (unreleased)
------------------------
+v2022.06.0 (July 21, 2022)
+--------------------------
+
+This release brings a number of bug fixes and improvements, most notably a major internal
+refactor of the indexing functionality, the use of `flox`_ in ``groupby`` operations,
+and experimental support for the new Python `Array API standard <https://data-apis.org/array-api/latest/>`_.
+It also stops testing support for the abandoned PyNIO.
+
+Much effort has been made to preserve backwards compatibility as part of the indexing refactor.
+We are aware of one `unfixed issue <https://github.com/pydata/xarray/issues/6607>`_.
+
+Please also see the `whats-new.2022.06.0rc0`_ for a full list of changes.
+
+Many thanks to our 18 contributors:
+Bane Sullivan, Deepak Cherian, Dimitri Papadopoulos Orfanos, Emma Marshall, Hauke Schulz, Illviljan,
+Julia Signell, Justus Magin, Keewis, Mathias Hauser, Michael Delgado, Mick, Pierre Manchon, Ray Bell,
