The link is to a private repository (although we have never denied someone who requests access.) It may become public some day. We encountered a problem when switching to version 10 or 11 of xarray, because of this fix, as we seemed to be combining strings and unicode in a `concat` operation. We have since fixed our specific bug, although we have not tracked down the exact combination of variables that led to upcasting to the object dtype.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,290320242 https://github.com/pydata/xarray/pull/1847#issuecomment-390728302,https://api.github.com/repos/pydata/xarray/issues/1847,390728302,MDEyOklzc3VlQ29tbWVudDM5MDcyODMwMg==,782050,2018-05-21T17:42:23Z,2018-05-21T17:42:23Z,NONE,Mention https://github.com/gafusion/OMFIT-source/pull/2734.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,290320242
