let me know what version number you would like - 0.30.1 or 0.31.0

Thanks!

The versions don't mean much, so 31 is fine. I'd like to merge in my fix in #421 when you decide to cut the next release.

I'm done, so we just need to decide who takes the reigns from here.

Mine is benign so let me merge that in.
