Have you tested this? If so, how?

I have not... will make modifications based on how the CI responds.

Hmm so docs won't build...
Sphinx 1.4.9 wants to import something that has been removed from Jinja2 (or rather the name has changed... contextfunction is now pass_context).
Would it be alright to try to increase the Sphinx version?

Yes, sorry. I fixed the build issues this weekend, but am waiting on an approval so that I can merge it.

If you'd like, you can try to give it an approval. I'm not sure if i can merge with any approval, or if it requires a maintainer approval. Although I have merge permissions, I cannot approve my own PR nor merge without an approval.

Once that unittest fix goes through, i have a few PR reviews to catch up on.

Sorry, but it seems that PR of yours requires review by a reviewer with write access. I do not have write access :(
