xarray auto_combine will be deprecated in version 0.13.

[Shadoward]

Hi,

The new version of xarray (0.13) will no longer use the auto_combine option.

C:\ProgramData\Anaconda3\lib\site-packages\xarray\backends\api.py:783: FutureWarning: In xarray version 0.13 `auto_combine` will be deprecated.

C:\ProgramData\Anaconda3\lib\site-packages\xarray\backends\api.py:783: FutureWarning: Also `open_mfdataset` will no longer accept a `concat_dim` argument.
To get equivalent behaviour from now on please use the new
`combine_nested` function instead (or the `combine='nested'` option to
`open_mfdataset`).The datasets supplied have global dimension coordinates. You may want
to use the new `combine_by_coords` function (or the
`combine='by_coords'` option to `open_mfdataset` to order the datasets
before concatenation. Alternatively, to continue concatenating based
on the order the datasets are supplied in in future, please use the
new `combine_nested` function (or the `combine='nested'` option to
open_mfdataset).
