You may need to refresh your cache to see the new versions.

I pushed some commits to the master branch of each of these to address 
editorial issues that came up. You may need to copy those commits to 
version branches, I haven't done that.

I filed an issue and pull request for things that I wasn't prepared to 
do in master as editorial issues, though I did them in the publication 
branch in order to be able to publish.
