v3.5.14

⚠️ The 3.5.x branch will not receive any update—including security fixes—after 2023-12-31.

⚠️ This release is an important security release fixing a major security issue (CVE-2023-42451).

Corresponding security releases are available for the 4.1.x branch and the 4.0.x branch.
If you are using nightly builds, do not use this release but update to nightly.2023-09-20 or newer instead. If you are on the main branch, update to the latest commit.

End of life notice

The 3.5.x branch will not receive any update after 2023-12-31.
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

Fixed

• Fix moderator rights inconsistencies (ClearlyClaire)
• Fix crash when encountering invalid URL (ClearlyClaire)
• Fix cached posts including stale stats (ClearlyClaire)
• Fix uploading of video files for which ffprobe reports 0/0 average framerate (NicolaiSoeborg)
• Fix unexpected audio stream transcoding when uploaded video is eligible to passthrough (yufushiro)

Security

• Fix incorrect domain name normalization (CVE-2023-42451, GHSA-v3xf-c9qf-j667)

Upgrade notes

To get the code for v3.5.14, use git fetch && git checkout v3.5.14.

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 v3.5.13, 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: >= 12.22, < 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 3.5.13.

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-rc1

⚠️ This is a pre-release! This has not been as widely tested as regular releases, although it is still tested on mastodon.social and some other servers. If you update to this release, you will not be able to safely downgrade to the existing stable releases. You will, however, be able to upgrade to later nightly releases as well as the upcoming 4.2.0 stable release.

Upgrade overview

This release contains upgrade notes that deviate from the norm:

ℹ️ Requires streaming API restart
ℹ️ Requires database migrations
ℹ️ Starting from this release, Mastodon will periodically check for updates (see below if you want to disable that behavior)
⚠️ Requires rebuilding Elasticsearch indexes
⚠️ 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
⚠️ Updated systemd unit files for the streaming server
⚠️ A configuration change is required for some S3-compatible storage providers
⚠️ We will stop bundling PgHero in a future release

Changelog

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 suspending a domain (ClearlyClaire, ClearlyClaire)
• Add support for importing lists (ClearlyClaire, mgmn, ClearlyClaire)
• Add optional hCaptcha support (ClearlyClaire, ClearlyClaire, Gargron, ClearlyClaire)
• Add lines to threads in web UI (Gargron, ClearlyClaire, ClearlyClaire, ClearlyClaire, ClearlyClaire, ClearlyClaire, ClearlyClaire, ClearlyClaire, teeerevor, renchap)
• Add new onboarding flow to web UI (Gargron, Gargron, Gargron, ClearlyClaire, ThisIsMissEm, Gargron, stevenjlm, ClearlyClaire, ClearlyClaire, Gargron, ClearlyClaire)
• Add S3_DISABLE_CHECKSUM_MODE environment variable for compatibility with some S3-compatible providers (ClearlyClaire)
• Add auto-refresh of accounts we get new messages/edits of (ClearlyClaire)
• **Add Elasticsearch cluster health...

• Fix wrong filters sometimes applying in streaming (ClearlyClaire, ThisIsMissEm, renchap)
• Fix incorrect connect timeout in outgoing requests (ClearlyClaire)

Upgrade notes

To get the code for v4.1.6, use git fetch && git checkout v4.1.6.

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 v4.1.5, 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 4.1.5.

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.

Non-Docker only:

1. Install dependencies: bundle install and yarn install

Both Docker and non-Docker:

1. Restart all Mastodon processes

v4.0.8

This is a backport for the 4.0.x branch.

⚠️ We recently released critical security updates, so if you are still using 4.1.2 or below, 4.0.4 or below, or 3.5.8 or below, please update as soon as possible (see the release notes for v4.0.6).
