So, I see from this commit that you're planning to move the version
number to 5.5.  I think this is a mistake.  We've been trying to be
more "conventional" in our project managment, and I think we should
stick with just incrementing the version.  There's no reason that 5.1
can't be a significant improvement over 5.0, and skipping versions
just adds potential for confusion.

Other than that, yay for GR2!
