The #Mastodon / Docker follies continue. Just did an entire new Mastodon install in Docker, and avoided most of the problems from before. In fact, the test instance started right up. BUT. Yeah. Even though docker-compose.yml specifies Mastodon v4.3.0, AND the running docker (docker ps) agrees with that -- the Mastodon About page and the actual source file version is once again 4.4.0alpha1. This is, well, very very odd, and needs to be understood. Because I'm just following the formula, and the wrong version is showing up.
