A good complement of bug fixes and new features. It may require extra dependencies. https://github.com/pydata/xarray/releases
0.16.0 is out. Similarly as for 0.15.1, a recent version of dask not yet in the tree is needed (https://xarray.pydata.org/en/stable/whats-new.html), so I added a blocker for that. AFAICT, other dependencies are not as major, but documentation on dependencies is not ideal. (Lists for CI are to be found in https://github.com/pydata/xarray/tree/v0.16.0/ci/requirements.)
