Changelog

Security

• Fix ActivityPub collection caching logic for pinned posts and featured tags not checking blocked accounts (GHSA-ccpr-m53r-mfwr)

Changed

• Shorten caching of quote posts pending approval (#37570 and #37592 by @ClearlyClaire)

Fixed

• Fix relationship cache not being cleared when handling account migrations (#37664 by @ClearlyClaire)
• Fix quote cancel button not appearing after edit then delete-and-redraft (#37066 by @PGrayCS)
• Fix followers with profile subscription (bell icon) being notified of post edits (#37646 by @ClearlyClaire)
• Fix error when encountering invalid tag in updated object (#37635 by @ClearlyClaire)
• Fix cross-server conversation tracking (#37559 by @ClearlyClaire)
• Fix recycled connections not being immediately closed (#37335 and #37674 by @ClearlyClaire and @shleeable)

Upgrade notes

To get the code for v4.5.6, use git fetch && git checkout v4.5.6.

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 v4.5.0.

• 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: 20.19 or newer
• libvips (optional, instead of ImageMagick): 8.13 or newer
• ImageMagick (optional if using libvips): 6.9.7-7 or newer

Update steps

The following instructions are for updating from 4.5.5.

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, it is very important to read the 4.5.0 release notes.

Non-Docker

Tip

The charlock_holmes gem may fail to build on some systems with recent versions of gcc.
If you run into this issue, try BUNDLE_BUILD__CHARLOCK_HOLMES="--with-cxxflags=-std=c++17" bundle install.

1. Precompile the assets: RAILS_ENV=production bundle exec rails assets:precompile
2. Restart all Mastodon processes.

When using Docker

1. Restart all Mastodon processes.
