update engine number, update NEWS.md

Hi Max,

I just realized I never updated the engine number, or the news when I added support for the arguments array. Also, npm seems to think it's on version 0.4.11, but the package.json shows 0.4.10. I noticed an extra tag from a year ago that might be confusing it. Can you publish the new version on npm? I imagine you're pretty busy, I read about Keybase in Wired, sounds pretty cool. Amusingly I just setup GPG a couple days ago. Thanks and best of luck.
