LGTM

One point of possible concern is that the version number collapses to 0.0 in all of our tracking.  I'm fine with this, but it's unfortunate, and possible confusing.  If the next version is 0.1, we're fine.  If the next version is 0.0.2, we have no way to distinguish.  Non-blocking, just noting.
