Upgrade notes
To get the code for v4.1.3, use git fetch && git checkout v4.1.3
.
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
Dependencies
Apart from ImageMagick, external dependencies have not changed compared to v4.1.2, 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 informations and ways to fix it on this page.
Update steps
The following instructions are for updating from 4.1.2.
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:
- Install dependencies:
bundle install
andyarn install
Both Docker and non-Docker:
ℹ️ The recommended configuration for reverse proxies has been updated. Unlike updating Mastodon itself, this is not urgent, but hardening. The change is about setting Content-Security-Policy: default-src 'none'; form-action 'none'
and X-Content-Type-Options: nosniff
on assets. Check dist/nginx.conf
for more information, and the documentation if you are proxying external object storage.
- Restart all Mastodon processes
