Upgrade notes

To get the code for v4.0.7, use git fetch && git checkout v4.0.7.

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

Dependencies

External dependencies have not changed compared to v4.0.6, the compatible Ruby, PostgreSQL, Node, Elasticsearch and Redis versions are the same, that is:

• Ruby: 2.7 to 3.0
• PostgreSQL: 9.5 or newer
• Elasticsearch (optional, for full-text search): 7.x
• Redis: 4 or newer
• Node: >= 14, < 18
• ImageMagick: 6.9.7-7 or newer

If your uploaded images are broken after the upgrade, it means your installed ImageMagick version is older than the new minimum version (6.9.7-7), for example if you are running Ubuntu 18.04. If this happens, you can find more information and ways to fix it on this page.

Update steps

The following instructions are for updating from 4.0.6.

If you are upgrading directly from an earlier release, please carefully read the upgrade notes for the skipped releases as well, as they often require extra steps such as database migrations.

Non-Docker only:

1. Install dependencies: bundle install and yarn install

Both Docker and non-Docker:

1. Restart all Mastodon processes
