This is a backport for the 3.3.x branch.

Changelog

Security

• Fix being able to bypass e-mail restrictions (Gargron)

Upgrade notes

Because this is a backport, it is not available with git pull. Use git fetch && git checkout v3.3.3

As always, make sure you have backups of the database before performing any upgrades. If you are using docker-compose, this is how a backup command might look: docker exec mastodon_db_1 pg_dump -Fc -U postgres postgres > name_of_the_backup.dump

Non-Docker

If you're upgrading from before 3.3.1, make sure you have shared-mime-info installed (apt install shared-mime-info), and also run bundle install between steps 1 and 2.

1. Pull the code: git fetch && git checkout v3.3.3
2. Restart mastodon-web and mastodon-sidekiq:
   systemctl reload mastodon-web
systemctl restart mastodon-sidekiq

Docker

The exact steps depend on your setup, but they are likely to match the following:

1. Pull the code: git fetch && git checkout v3.3.3
2. Pull the prebuilt images: docker-compose pull, or, alternatively, build them yourself: docker-compose build --pull
3. Restart all Mastodon processes: docker-compose up -d
