Added! I'm a first time contributor to pandas - let me know if that whatsnew entry was appropriate. @jreback I merged master but it doesn't look like the build failures are a result of changes from this PR.  Fixing that in another PR. You can ignore it for now. Awesome, let me know if there's anything else we need in here. Thanks a lot @ieaves !
