329017956,MDExOlB1bGxSZXF1ZXN0MzI5MDE3OTU2,3410,closed,0,Update Terminology page to account for multidimensional coordinates,3460034,"As discussed in https://github.com/pydata/xarray/pull/3352, this PR modifies the Terminology page in the docs to briefly address multidimensional coordinates. Sorry for the delay in getting this in!

Also, when attempting to test the doc build, I found that the `doc/environment.yml` file was no longer present, so I updated it to `ci/requirements/doc.yml`.

1197041777,PR_kwDOAMm_X85HWWhx,7437,open,0,DRAFT: Implement `open_datatree` in BackendEntrypoint for preliminary DataTree support,3460034,"<!-- Feel free to remove check-list items aren't relevant to your change -->

As discussed among folks at today's Pangeo working meeting (cc @jhamman, @TomNicholas), we are looking to try adding support for `DataTree` in the Backend API, so that backend engines can readily add `DataTree` capability. For example, with `cfgrib`, we could have

```python
import xarray as xr

dt = xr.open_datatree(""path/to/gribfile.grib"", engine=""cfgrib"")
```

given that `cfgrib` implements the appropriate method to their `BackendEntrypoint` subclass. Similarly, with NetCDF files or Zarr stores with groups, we could open as `DataTree` to obviate the need to specify a single group.
