v2023.08.0

This release brings changes to minimum dependencies, allows reading of datasets where a dimension name is
associated with a multidimensional variable (e.g. finite volume ocean model output), and introduces
a new :py:class:xarray.Coordinates object.

Thanks to the 16 contributors to this release: Anderson Banihirwe, Articoking, Benoit Bovy, Deepak Cherian, Harshitha, Ian Carroll,
Joe Hamman, Justus Magin, Peter Hill, Rachel Wegener, Riley Kuttruff, Thomas Nicholas, Tom Nicholas, ilgast, quantsnus, vallirep

Announcements

The xarray.Variable class is being refactored out to a new project title 'namedarray'.
