v4.1.20

Changelog

Security

• Fix ReDoS vulnerability on some Ruby versions (GHSA-jpxp-r43f-rhvx)
• Update dependencies

Changed

• Change Mastodon to issue correct HTTP signatures by default (#31994 by @ClearlyClaire)

Fixed

• Fix replies collection being cached improperly
• Fix security context sometimes not being added in LD-Signed activities (#31871 by @ClearlyClaire)
• Fix error when encountering reblog of deleted post in feed rebuild (#32001 by @ClearlyClaire)

Upgrade notes

To get the code for v4.1.20, use git fetch && git checkout v4.1.20.

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

Important

Since v4.1.18, Mastodon is now performing stricter checks to prevent client IP address spoofing. This means that if one of your reverse proxy is not on Mastodon's local network, you will need to set TRUSTED_PROXY_IP accordingly, listing the IP address of every trusted reverse-proxy (including local network ones). See the documentation for more information.

Dependencies

Warning

The minimum required Ruby version has been bumped to 3.0 in Mastodon v4.1.14.

External dependencies have not changed compared to v4.1.14, the compatible Ruby, PostgreSQL, Node, Elasticsearch and Redis versions are the same, that is:

• Ruby: 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

Update steps

The following instructions are for updating from 4.1.19.

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

v4.3.0-beta.2

Warning

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, prereleases as well as the upcoming 4.3.0 stable release.

Changelog (v4.3.0-beta.1)

The following changelog entries focus on changes visible to users, administrators, client developers or federated software developers, but there has also been a lot of code modernization, refactoring, and tooling work, in particular by @mjankowski.

Security

• Add confirmation interstitial instead of silently redirecting logged-out visitors to remote resources (#27792, #28902, and #30651 by @ClearlyClaire and @Gargron)
  This fixes a longstanding open redirect in Mastodon, at the cost of added friction when local links to remote resources are shared.

Added

• Add experimental server-side notification grouping (#29889, #30576, #30685, #30688, #30707, #30776, #30779, #30781, #30440, #31062, #31098, #31076, #31111, #31123, #31223, #31214, #31224, #31299, #31325, #31347, #31304, #31326, #31384, #31403, #31433, #31509, #31486, and #31513 by @ClearlyClaire, @mgmn, and @renchap)
  Group notifications of the same type for the same target, so that your notifications no longer get cluttered by boost and favorite notifications as soon as a couple of your posts get traction.
  This is done server-side so that clients can efficiently get relevant groups without having to go through numerous pages of individual notifications.
  As part of this, the visual design of the entire notifications feature has been revamped.
  This feature is intended to eventually replace the existing notifications column, but for this first beta, users will have to enable it in the “Experimental features” section of the notifications column settings.
  The API is not final yet, but it consists of:
  • a new group_key attribute to Notification entities
  • GET /api/v2_alpha/notifications: https://docs.joinmastodon.org/methods/notifications_alpha/#get-grouped
  • GET /api/v2_alpha/notifications/:group_key: https://docs.joinmastodon.org/methods/notifications_alpha/#get-notification-group
  • POST /api/v2_alpha/notifications/:group_key/dimsiss: https://docs.joinmastodon.org/methods/notifications_alpha/#dismiss-group
  • GET /api/v2_alpha/notifications/:unread_count: https://docs.joinmastodon.org/methods/notifications_alpha/#unread-group-count
• Add notification policies, filtered notifications and notification requests (#29366, #29529, #29433, #29565, #29567, #29572, #29575, #29588, #29646, #29652, #29658, #29666, #29693, #29699, #29737, #29706, #29570, #29752, #29810, #29826, #30114, #30251, #30559, #29868, #31008, #31011, #30996, #31149, #31220, #31222, #31225, #31242, #31262, #31250, #31273, #31310, #3131...

  • GET /api/v2_alpha/notifications/:unread_count: https://docs.joinmastodon.org/methods/notifications_alpha/#unread-group-count

• Add notification policies, filtered notifications and notification requests (#29366, #29529, #29433, #29565, #29567, #29572, #29575, #29588, #29646, #29652, #29658, #29666, #29693, #29699, #29737, #29706, #29570, #29752, #29810, #29826, #30114, #30251, #30559, #29868, #31008, #31011, #30996, #31149, #31220, #31222, #31225, #31242, #31262, #31250, #31273, #31310, #31316, #31322, #31329, #31324, #31331, #31343, #31342, #31309, #31358, #31378, #31406, #31256, #31456, #31419, #31457, #31508, #31540, and #31541 by @ClearlyClaire, @Gargron, @TheEssem, @mgmn, @oneiros, and @renchap)
  The old “Block notifications from non-followers”, “Block notifications from people you don't follow” and “Block direct messages from people you don't follow” notification settings have been replaced by a new set of settings found directly in the notification column.
  You can now separately filter or drop notifications from people you don't follow, people who don't follow you, accounts created within the past 30 days, as well as unsolicited private mentions, and accounts limited by the moderation.
  Instead of being outright dropped, notifications that you chose to filter are put in a separate “Filtered notifications” box that you can review separately without it clogging your main notifications.
  This adds the following REST API endpoints:

  • GET /api/v2/notifications/policy: https://docs.joinmastodon.org/methods/notifications/#get-policy
  • PATCH /api/v2/notifications/policy: https://docs.joinmastodon.org/methods/notifications/#update-the-filtering-policy-for-notifications
  • GET /api/v1/notifications/requests: https://docs.joinmastodon.org/methods/notifications/#get-requests
  • GET /api/v1/notifications/requests/:id: https://docs.joinmastodon.org/methods/notifications/#get-one-request
  • POST /api/v1/notifications/requests/:id/accept: https://docs.joinmastodon.org/methods/notifications/#accept-request
  • POST /api/v1/notifications/requests/:id/dismiss: https://docs.joinmastodon.org/methods/notifications/#dismiss-request
  • POST /api/v1/notifications/requests/accept: https://docs.joinmastodon.org/methods/notifications/#accept-multiple-requests
  • POST /api/v1/notifications/requests/dismiss: https://docs.joinmastodon.org/methods/notifications/#dismiss-multiple-requests
  • GET /api/v1/notifications/requests/merged: https://docs.joinmastodon.org/methods/notifications/#requests-merged

  In addition, accepting one or more notification requests generates a new streaming event:

  • notifications_merged: an event of this type indicates accepted notification requests have finished merging, and the notifications list should be refreshed

• Add notifications of severed relationships (#27511, #29665, #29668, #29670, #29700, #29714, #29712, and #29731 by @ClearlyClaire and @Gargron)
  Notify local users when they lose relationships as a result of a local moderator blocking a remote account or server, allowing the affected user to retrieve the list of broken relationships.
  Note that this does not notify remote users.
  This adds the severed_relationships notification type to the REST API and streaming, with a new relationship_severance_event attribute.

• Add hover cards in web UI (#30754, #30864, #30850, #30879, #30928, #30949, #30948, #30931, and #31300 by @ClearlyClaire, @Gargron, and @renchap)
  Hovering over an avatar or username will now display a hover card with the first two lines of the user's description and their first two profile fields.
  This can be disabled in the “Animations and accessibility” section of the preferences.

• Add "system" theme setting (light/dark theme depending on user system preference) (#29748, #29553, #29795, #29918, #30839, and #30861 by @nshki, @ErikUden, @mjankowski, @renchap, and @vmstan)
  Add a “system” theme that automatically switch between default dark and light themes depending on the user's system preferences.
  Also changes the default server theme to this new “system” theme so that automatic theme selection happens even when logged out.

• Add timeline of public posts about a trending link (#30381 and #30840 by @Gargron)
  You can now see public posts mentioning currently-trending articles from people who have opted into discovery features.
  This adds a new REST API endpoint: https://docs.joinmastodon.org/methods/timelines/#link

• Add author highlight for news articles whose authors are on the fediverse (#30398, #30670, #30521, and #30846 by @Gargron)
  This adds a mechanism to highlight the author of news articles shared on Mastodon.
  Articles hosted outside the fediverse can indicate a fediverse author with a meta tag:

  <meta name="fediverse:creator" content="username@domain" />

  On the API side, this is represented by a new authors attribute to the PreviewCard entity: https://docs.joinmastodon.org/entities/PreviewCard/#authors\
  Note that this feature is still work in progress and the tagging format and verification mechanisms may change in future releases.

• Add in-app notifications for moderation actions and warnings (#30065, #30082, and #30081 by @ClearlyClaire)
  In addition to email notifications, also notify users of moderation actions or warnings against them directly within the app, so they are less likely to miss important communication from their moderators.
  This adds the moderation_warning notification type to the REST API and streaming, with a new moderation_warning attribute.

• Add domain information to profiles in web UI (#29602 by @Gargron)
  Clicking the domain of a user in their profile will now open a tooltip with a short explanation about servers and federation.

• Add ability to reorder upload...

Upgrade notes

To get the code for v4.2.12, use git fetch && git checkout v4.2.12.

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

Important

Since v4.2.10, Mastodon is now performing stricter checks to prevent client IP address spoofing. This means that if one of your reverse proxy is not on Mastodon's local network, you will need to set TRUSTED_PROXY_IP accordingly, listing the IP address of every trusted reverse-proxy (including local network ones). See the documentation for more information.

Dependencies

With the exception of Ruby's recommended version, external dependencies have not changed since v4.2.0, the compatible Ruby, PostgreSQL, Node, Elasticsearch and Redis versions are the same, that is:

• Ruby: 3.0 to 3.2
• PostgreSQL: 10 or newer
• 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: 16 or newer
• ImageMagick: 6.9.7-7 or newer

Update steps

Tip

The charlock_holmes gem may fail to build on some systems with recent versions of gcc.

The following instructions are for updating from 4.2.10 or 4.2.11.

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

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

The following instructions are for updating from 4.2.10.

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

Using Docker:

1. Restart all Mastodon processes

Upgrade notes

To get the code for v4.1.19, use git fetch && git checkout v4.1.19.

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

Important

Since v4.1.18, Mastodon is now performing stricter checks to prevent client IP address spoofing. This means that if one of your reverse proxy is not on Mastodon's local network, you will need to set TRUSTED_PROXY_IP accordingly, listing the IP address of every trusted reverse-proxy (including local network ones). See the documentation for more information.
