Seems like a pretty sweet release: http://facebook.github.io/jest/blog/2017/02/21/jest-19-immersive-watch-mode-test-platform-improvements.html.

This is a breaking change so targeting 0.10. A PR to update is welcome.
Also worth keeping an eye on jestjs/jest#2957.
