v4.0.11

⚠️ The 4.0.x branch will not receive any update—including security fixes—after 2023-10-31.

This release addresses an issue that was introduced by the last security update and includes changelogs for both updates.

⚠️ This is a follow-up to the important 4.0.10 security update that fixed major security issues (CVE-2023-42451, CVE-2023-42452).

Corresponding security releases are available for the 4.1.x branch and the 3.5.x branch.

End of life notice

The 4.0.x branch will not receive any update after 2023-10-31.
This means that no security fix will be made available for this branch after this date, and you will need to update to a more recent version (such as the 4.1.x branch) to receive security fixes.

Changelog (v4.0.11)

Fixed

• Fix post translation erroring out (ClearlyClaire)

Changelog (v4.0.10)

Fixed

• Fix moderator rights inconsistencies (ClearlyClaire)
• Fix crash when encountering invalid URL (ClearlyClaire)
• Fix cached posts including stale stats (ClearlyClaire)

Upgrade notes

To get the code for v4.0.11, use git fetch && git checkout v4.0.11.

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 compared to v4.0.9, 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 information and ways to fix it on this page.

Update steps

The following instructions are for updating from 4.0.9 or 4.0.10.

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.

Non-Docker only:

1. Install dependencies: bundle install and yarn install --frozen-lockfile

Both Docker and non-Docker:

1. Restart all Mastodon processes

v4.2.0-rc2

You will, however, be able to upgrade to later nightly releases as well as the upcoming 4.2.0 stable release.

⚠️ This release is an important security release fixing major security issues (CVE-2023-42451, CVE-2023-42452, CVE-2023-42450).

Corresponding security releases are available for the 4.1.x branch, the 4.0.x branch and the 3.5.x branch.

⚠️ The minimal supported version for Ruby has been bumped to 3.0
⚠️ The minimal supported version for Node.js has been bumped to 16
⚠️ The minimal supported version for PostgreSQL has been bumped to 10. Please note that using PostgreSQL 10 or 11 is deprecated and will not be supported in 4.3.0.
⚠️ The minimal supported version for LibreTranslate has been bumped to 1.3.3
⚠️ The way database replicas are configured has changed
⚠️ Disables part of the StatsD integration by default
⚠️ Drops built-in clustering support from the streaming server

Fixed

• Fix hashtag bar being sometimes incorrectly hidden (ClearlyClaire)
• Fix crash when viewing a moderation appeal and the moderator account has been deleted (xrobau)

• Fix processing of min_id and max_id parameters in /api/v2/search (ClearlyClaire)

Security

• Fix incorrect URL normalization (CVE-2023-42450, GHSA-hcqf-fw2r-52g4)
• Fix missing HTML sanitization in translation API (CVE-2023-42452, GHSA-2693-xr3m-jhqr)
• Fix incorrect domain name normalization (CVE-2023-42451, GHSA-v3xf-c9qf-j667)

Changelog (v4.2.0-rc1)

Added

• Add full-text search of opted-in public posts and rework search operators (Gargron, jsgoldstein, ClearlyClaire, ClearlyClaire, jsgoldstein, Gargron, Gargron, Gargron, Gargron, Gargron, Gargron, Gargron, ClearlyClaire, Gargron, Gargron, ClearlyClaire, ClearlyClaire, ClearlyClaire, Gargron, ClearlyClaire, Gargron, Gargron, Gargron, ClearlyClaire, Gargron, Gargron, Gargron, Gargron, Gargron, arbolitoloco1, tribela)
  This introduces a new public_statuses Elasticsearch index for public posts by users who have opted in to their posts being searchable (toot#indexable flag).
  This also revisits the other indexes to provide more useful indexing, and adds new search operators such as from:me, before:2022-11-01, after:2022-11-01, during:2022-11-01, language:fr, has:poll, or in:library (for searching only in posts you have written or interacted with).
  Results are now ordered chronologically.
• Add admin notifications for new Mastodon versions (ClearlyClaire)
  This is done by querying https://api.joinmastodon.org/update-check every 30 minutes in a background job.
  That URL can be changed using the UPDATE_CHECK_URL environment variable, and the feature outright disabled by setting that variable to an empty string (UPDATE_CHECK_URL=).
• Add “Privacy and reach” tab in profile settings (Gargron, ClearlyClaire)
  This reorganized scattered privacy and reach settings to a single place, as well as improve their wording.
• Add display of out-of-band hashtags in the web interface (Gargron, arbolitoloco1, ClearlyClaire, ClearlyClaire, ClearlyClaire, Gargron)
• Add role badges to the web interface (ClearlyClaire, Gargron)
• Add ability to pick domains to forward reports to using the forward_to_domains parameter in POST /api/v1/reports (ClearlyClaire, ClearlyClaire)
  The forward_to_domains REST API parameter is a list of strings. If it is empty or omitted, the previous behavior is maintained.
  The forward parameter still needs to be set for forward_to_domains to be taken into account.
  The forwarded-to domains can only include that of the original author and people being replied to.
• Add forwarding of reported replies to servers being replied to (Gargron, ClearlyClaire)
• Add ONE_CLICK_SSO_LOGIN environment variable to directly link to the Single-Sign On provider if there is only one sign up method available (CSDUMMI, ClearlyClaire, CSDUMMI, ClearlyClaire)
• Add webhook templating (Gargron)
• Add webhooks for local status.created, status.updated, account.updated and report.updated (VyrCossont, VyrCossont, VyrCossont)
• Add exclusive lists (dariusk, necropolina, ClearlyClaire)
• **Add a confirmation screen when s...

• Add full-text search of opted-in public posts and rework search operators (Gargron, jsgoldstein, ClearlyClaire, ClearlyClaire, jsgoldstein, Gargron, Gargron, Gargron, Gargron, Gargron, Gargron, Gargron, ClearlyClaire, Gargron, Gargron, ClearlyClaire, ClearlyClaire, ClearlyClaire, Gargron, ClearlyClaire, Gargron, Gargron, Gargron)
  This introduces a new public_statuses Elasticsearch index for public posts by users who have opted in to their posts being searchable (toot#indexable flag).
  This also revisits the other indexes to provide more useful indexing, and adds new search operators such as from:me, before:2022-11-01, after:2022-11-01, during:2022-11-01, language:fr, has:poll, or in:library (for searching only in posts you have written or interacted with).
  Results are now ordered chronologically.

  This is done by querying https://api.joinmastodon.org/update-check every 30 minutes in a background job.
