Then I'm not sure I understand the change: fridge = xarray.Dataset( data_vars={ 'fruits': ('fruit', [10]), }, coords={ 'fruit': ('fruit', ['apples']), 'quality': ('fruit', ['Red Velvet']), }) shopping = xarray.Dataset( data_vars={ 'fruits': ('fruit', [20]), }, coords={ 'fruit': ('fruit', ['oranges']), 'quality': ('fruit', ['Tangerine']), }) fridge.update(shopping) # throw away old contents and fill with new stuff In both 0.10.3 and 0.10.4: <xarray.Dataset> Dimensions: (fruit: 1) Coordinates: * fruit (fruit) object 'apples' quality (fruit) object nan Data variables: fruits (fruit) float64 nan The above doesn't make any sense to me. I wanted to replace the fruits variable with brand new content, and instead I lost both the old and the new?!?
