Not fully convinced that the name to_branch is the best one to use here. Maybe base_branch? Feel free to ignore.

I'm tempted to try to use the TO_BRANCH variable here to try to make sure we identify a tag that matches the major version of our target branch, though it may not be necessary. Feel free to ignore this suggestion.

Beware, this has a broken syntax
