We don’t necessarily decide the version numbers for all of the libraries in 
advance. I think we talked about this on IRC, and your suggestion was to use a 
“next” milestone and then rename it at the point of release. Am I remembering 
correctly?

This makes sense to me, so let’s move ahead with your plan.

It would be good if we had a script to automate some of the release processes 
now, and it seems like this change is going to make it easier to implement 
parts like marking all of the tickets as released and updating their milestone.

We do have launchpad projects for some of the other oslo libraries, we just 
haven’t been using them for release tracking:
