    Indexing now supports broadcasting over dimensions, similar to NumPy’s vectorized indexing (but better!). resample() has a new groupby-like API like pandas. apply_ufunc() facilitates wrapping and parallelizing functions written for NumPy arrays. Performance improvements, particularly for dask and open_mfdataset().
