 That's a good point, we do need to run CI on all supported versions.
However, I think that updates to the release branches are not nearly as
frequent as updates to master branch. So, I think it might actually be
reasonable to run CI on ~10 release branches, since we will only need to
run it when bug fixes get backported.
