It looks like dask 0.16 or distributed 0.1.20 release is the most likely culprit. There were no Python changes to xarray in the v0.10.0 release commit (only `setup.py` and documentation changes).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,276241193

anything relevant in xarray so my guess is something to do with a
dependency. Hopefully it will be clear from the appveyor logs!
