The main change is that we've retired the old bridge authority, and replaced it with a new one that we are optimistic will get more consistent maintenance attention. So the main people who need to upgrade are people who operate a bridge relay -- so their bridge address can resume being given out to censored users, and so their stats can resume being included in the metrics pages.

I've also made git tags for each, and pushed those to git.
