    Happy 1.0!

    1. I’ve tried to get the numbers that apply leading up to the 1.0 release exactly, e.g. using the exact tag of the release for code related things, and generally trying to show the value as it was on/before May 15. I’ve put a ~ on particularly dubious numbers and those for which I can’t get the true 1.0 value, but most probably have too many significant figures anyway: this definitely isn’t meant to be at all scientific.
