Upgrade notes

To get the code for v4.0.2, use git fetch && git checkout v4.0.2.

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

Update steps

The following instructions are for updating from 4.0.0 or 4.0.1.

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. You can use the 4.0.0 upgrade notes to upgrade directly to 4.0.2.

Non-Docker only:

• Install dependencies: bundle install

Both Docker and non-Docker:

1. Precompile the assets:
   • Non-Docker: RAILS_ENV=production bundle exec rails assets:precompile
   • Docker: The assets are already precompiled during the build step
2. Restart all Mastodon processes
