 @adamhooper do you know if / when you'll be able to update? I'm cutting the RC soon (hopefully a couple hours from now).

If you're busy now I can push the changes and then we'll get this merged before the RC. Test failures from travis were unrelated. Fixing in https://github.com/pandas-dev/pandas/pull/20906 Failures should be fixed in masater. Thanks @adamhooper! Er ... finally I'm available to fix things. You beat me to it -- thanks! Thank you! I'm glad we could get this in before the release.
