Last call for v0.11.1

[shoyer]

@pydata/xarray I'm going to issue v0.11.1 in a day or two, unless there's anything else we really want to squeeze in. This is the last release with planned Python 2.7 support (but we could conceivably still do backports for nasty bugs).

#2413?

[shoyer]

I just tagged 0.11.1 and pushed it to pypi. RTD and conda-forge should take care of themselves.

Thanks @shoyer!
