Is writewithharper.com using the code in HEAD?

Is writewithharper.com using the code from latest release or from the most recent successful build from the master in the repo?

I'm assuming it's running the release version in which case why not stir up interest with a "try out new features coming soon" banner.

We could also show the latest build by default but have a switch to try the latest version instead - for extra coolness, on switching it would make any extra or different lints glow or some other effect to draw attention to them.

It should at least tell you which version it's using - maybe the release date and time of the version it's using or telling you "how recently ago" the version it's running came out.
