-Xarray's GroupBy operations are currently limited:
-
-1. One can only group by a single variable.
-1. When grouping by a dask array, that array will be computed to discover the unique group labels, and their locations
-
-These limitations can be avoided by using {py:func}`flox.xarray.xarray_reduce` which allows grouping by multiple variables, lazy grouping by dask variables,
-as well as an arbitrary combination of categorical grouping and binning. For example,
-
-```python
-flox.xarray.xarray_reduce(
-    ds,
-    ds.time.dt.month,
-    ds.lon,
-    func="mean",
-    expected_groups=[None, [0, 10, 20]],
-    isbin=[False, True],
-    method="map-reduce",
-)
-```
+{py:func}`flox.xarray.xarray_reduce` used to provide extra functionality, but now Xarray's GroupBy object has been upgraded to match those capabilities with better API!
