Upgrade notes
To get the code for v4.3.11, use git fetch && git checkout v4.3.11.
[!NOTE] 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 since v4.3.0, the compatible Ruby, PostgreSQL, Node, Elasticsearch and Redis versions are the same, that is:
- Ruby: 3.1 or newer
- PostgreSQL: 12 or newer. PostgreSQL versions 14.0 to 14.3 are not supported as they contain a critical data-corruption bug (see v4.3.0 release notes)
- Elasticsearch (recommended, for full-text search): 7.x (OpenSearch should also work)
- LibreTranslate (optional, for translations): 1.3.3 or newer
- Redis: 4 or newer
- Node: 18 or newer
- ImageMagick (optional if using libvips): 6.9.7-7 or newer
- libvips (optional, instead of ImageMagick): 8.13 or newer
Update steps
The following instructions are for updating from 4.3.10.
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. In particular, please read the v4.3.0 release notes, as there have been multiple important changes.
