Upgrade notes

To get the code for v4.5.0, use git fetch && git checkout v4.5.0.

Dependencies

External dependencies have changed since v4.4.0, with the Redis and PostgreSQL minimum version being higher.

• Ruby: 3.2 or newer
• PostgreSQL: 14 or newer
• Elasticsearch (recommended, for full-text search): 7.x (OpenSearch should also work)
• LibreTranslate (optional, for translations): 1.3.3 or newer
• Redis: 7.0 or newer
• Node: 20 or newer
• libvips (optional, instead of ImageMagick): 8.13 or newer
• ImageMagick (optional if using libvips): 6.9.7-7 or newer

Sidekiq update and health checks

We have updated Sidekiq from Sidekiq 7 to Sidekiq 8, but the health check we used to provide in docker-compose.ymlspecifically checks for Sidekiq 7. If you use docker-compose.yml from the release, it has already been updated. But if you copied or adapted the old health check, you will need to update it to test for Sidekiq 8.

Instead of the following line:

test: ['CMD-SHELL', "ps aux | grep '[s]idekiq\ 7' || false"]

It should read:

test: ['CMD-SHELL', "ps aux | grep '[s]idekiq\ 8' || false"]

Update steps

The following instructions are for updating from 4.4.8.

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. If you are upgrading from a pre-4.3 version, please fully update to Mastodon 4.3 first or stop all Mastodon processes before updating, and please have a look at the “Ongoing import jobs from Mastodon 4.1 and earlier” section of Mastodon 4.4.0's release notes if you are updating from a pre-4.2 version.

Non-Docker

1. If you are using rbenv, update the list of available versions and install the proper Ruby version by doing RUBY_CONFIGURE_OPTS=--with-jemalloc rbenv install in the Mastodon install directory (e.g. /home/mastodon/live)
2. Install dependencies with bundle install and yarn install --immutable
3. Precompile the assets: RAILS_ENV=production bundle exec rails assets:precompile
4. Run the pre-deployment database migrations by specifying the SKIP_POST_DEPLOYMENT_MIGRATIONS=true environment variable: SKIP_POST_DEPLOYMENT_MIGRATIONS=true RAILS_ENV=production bundle exec rails db:migrate
5. Restart all Mastodon processes.
6. Run the post-deployment database migrations: RAILS_ENV=production bundle exec rails db:migrate

When using Docker

1. Run the pre-deployment database migrations by specifying the SKIP_POST_DEPLOYMENT_MIGRATIONS=true environment variable: docker-compose run --rm -e SKIP_POST_DEPLOYMENT_MIGRATIONS=true web bundle exec rails db:migrate
2. Restart all Mastodon processes.
3. Run the post-deployment database migrations: docker-compose run --rm web bundle exec rails db:migrate
