1. You'll need to also add a note to `doc/whats-new.rst`.
2. Looks like there's trailing whitespace in `test_variable.py` that will need to be fixed.

EDIT: Looks like the tests aren't running because of this ImportError

```
ImportError while importing test module '/home/travis/build/pydata/xarray/xarray/tests/test_variable.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
xarray/tests/test_variable.py:27: in <module>
    from . import (
E   ImportError: cannot import name 'set_options'
```

I think you need `from xarray import set_options` as in `test_dataset.py`. You can test this out locally using pytest. We have some documentation on contributing here: http://xarray.pydata.org/en/stable/contributing.html.
