Surprise! We actually updated to 4.3.0-alpha.0+glitch and we're now enjoying some new unreleased features for Mastodon. We don't know the breadth of these features, but if you encounter issues, make sure to report them to the Mastodon developers here: https://github.com/mastodon/mastodon
Sidekiq will remain on DigitalOcean as we have ran out of maintenance window time. This work will be done over the coming week without scheduling a maintenance window as it isn't member facing.
