Changelog

Added

• Add more explicit explanations about author attribution and fediverse:creator (#​32383 by @​ClearlyClaire)
• Add ability to group follow notifications in WebUI, can be disabled in the column settings (#​32520 by @​renchap)
• Add back a 6 hours mute duration option (#​32522 by @​renchap)
• Add note about not changing ActiveRecord encryption secrets once they are set (#​32413, #​32476, #​32512, and #​32537 by @​ClearlyClaire and @​mjankowski)

Changed

• Change translation feature to translate to selected regional variant (e.g. pt-BR) if available (#​32428 by @​c960657)

Removed

• Remove ability to get embed code for remote posts (#​32578 by @​ClearlyClaire)
  Getting the embed code is only reliable for local posts.
  It never worked for non-Mastodon servers, and stopped working correctly with the changes made in 4.3.0.
  We have therefore decided to remove the menu entry while we investigate solutions.

Upgrade notes

To get the code for v4.3.1, use git fetch && git checkout v4.3.1.

[!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 v4.3.0, the compatible Ruby, PostgreSQL, Node, Elasticsearch and Redis versions are the same, that is:

• Ruby: 3.1 or newer
• PostgreSQL: 12 or newer. PostgreSQL versions 14.0 to 14.3 are not supported as they contain a critical data-corruption bug (see v4.3.0 release notes)
• 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: 18 or newer
• ImageMagick (optional if using libvips): 6.9.7-7 or newer
• libvips (optional, instead of ImageMagick): 8.13 or newer

Update steps

The following instructions are for updating from 4.3.0.

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, please read the v4.3.0 release notes, as there have been multiple important changes.

Non-docker

[!TIP] 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.

1. Install dependencies with bundle install and yarn install --immutable
2. Precompile the assets: RAILS_ENV=production bundle exec rails assets:precompile
3. Restart all Mastodon processes.

When using docker

1. Restart all Mastodon processes.

Changelog

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.
• Fix ReDoS vulnerability on some Ruby versions (GHSA-jpxp-r43f-rhvx)
• Change form-action Content-Security-Policy directive to be more restrictive (#​26897 and #​32241 by @​ClearlyClaire)
• Update dependencies

Added

• Add 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, #​31513, #​31592, #​31594, #​31638, #​31746, #​31652, #​31709, #​31725, #​31745, #​31613, #​31657, #​31840, #​31610, #​31929, #​32089, #​32085, #​32243, #​32179 and #​32254 by @​ClearlyClaire, @​Gargron, @​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.
  The API consists of:

  • a new group_key attribute to Notification entities
  • GET /api/v2/notifications: https://docs.joinmastodon.org/methods/grouped_notifications/#get-grouped
  • GET /api/v2/notifications/:group_key: https://docs.joinmastodon.org/methods/grouped_notifications/#get-notification-group
  • GET /api/v2/notifications/:group_key/accounts: https://docs.joinmastodon.org/methods/grouped_notifications/#get-group-accounts
  • POST /api/v2/notifications/:group_key/dimsiss: https://docs.joinmastodon.org/methods/grouped_notifications/#dismiss-group
  • GET /api/v2/notifications/:unread_count: https://docs.joinmastodon.org/methods/grouped_notifications/#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, #​31541, #​31723, #​32062 and #​32281 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:

  • GET /api/v1/timelines/link?url=:url: https://docs.joinmastodon.org/methods/timelines/#link

• Add author highlight for news articles whose authors are on the fediverse (#​30398, #​30670, #​30521, #​30846, #​31819, #​31900 and #​32188 by @​Gargron, @​mjankowski and @​oneiros)
  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
  Users can allow arbitrary domains to use fediverse:creator to credit them by visiting /settings/verification.
  This is federated as a new attributionDomains property in the http://joinmastodon.org/ns namespace, containing an array of domain names: https://docs.joinmastodon.org/spec/activitypub/#properties-used-1

• 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 support for Redis sentinel (#​31694, #​31623, #​31744, #​31767, and #​31768 by @​ThisIsMissEm and @​oneiros)
  See https://docs.joinmastodon.org/admin/scaling/#redis-sentinel

• Add ability to reorder uploaded media before posting in web UI (#​28456 and #​32093 by @​Gargron)

  This is also exposed through the REST API: https://docs.joinmastodon.org/entities/Instance/#icon

• Add api_versions to /api/v2/instance (#​31354 by @​ClearlyClaire)
  Add API version number to make it easier for clients to detect compatible features going forward.

  In addition, better care is given to pixel alignment, and icon variants are used to better highlight active/inactive state.
• Change design of compose form in web UI (#​28119, #​29059, #​29248, #​29372, #​29384, #​29417, #​29456, #​29406, #​29651, #​29659, #​31889 and #​32033 by @​ClearlyClaire, @​Gargron, @​eai04191, @​hinaloe, and @​ronilaukkarinen)
  The compose form has been completely redesigned for a more modern and consistent look, as well as spelling out the chosen privacy setting and language name at all times.
  As part of this, the “Unlisted” privacy setting has been renamed to “Quiet public”.
• Change design of modals in the web UI (#​29576, #​29614, #​29640, #​29644, #​30131, #​30884, #​31399, #​31555, #​31752, #​31801, #​31883, #​31844, #​31864, and #​31943 by @​ClearlyClaire, @​Gargron, @​tribela and @​vmstan)
  The mute, block, and domain block confirmation modals have been completely redesigned to be clearer and include more detailed information on the action to be performed.
  They also have a more modern and consistent design, along with other confirmation modals in the application.
• Change colors throughout the web UI (#​29522, #​29584, #​29653, #​29779, #​29803, #​29809, #​29808, #​29828, #​31034, #​31168, #​31266, #​31348, #​31349, #​31361, #​31510 and #​32128 by @​ClearlyClaire, @​Gargron, @​mjankowski, @​renchap, and @​vmstan)
• Change onboarding prompt to follow suggestions carousel in web UI (#​28878, #​29272, and #​31912 by @​Gargron)
• Change email templates (#​28416, #​28755, #​28814, #​29064, #​28883, #​29470, #​29607, #​29761, #​29760, #​29879, #​32073 and #​32132 by @​c960657, @​ClearlyClaire, @​Gargron, @​hteumeuleu, and @​mjankowski)
  All emails to end-users have been completely redesigned with a fresh new look, providing more information while making them easier to read and keeping maximum compatibility across mail clients.
• Change follow recommendations algorithm (#​28314, #​28433, #​29017, #​29108, #​29306, #​29550, #​29619, and #​31474 by @​ClearlyClaire, @​Gargron, @​kernal053, @​mjankowski, and @​wheatear-dev)
  This replaces the “past interactions” recommendation algorithm with a “friends of friends” algorithm that suggests accounts followed by people you follow, and a “similar profiles” algorithm that suggests accounts with a profile similar to your most recent follows.
  In addition, the implementation has been significantly reworked, and all follow recommendations are now dismissable.
  This change deprecates the source attribute in Suggestion entities in the REST API, and replaces it with the new sources attribute.
• Change account search algorithm (#​30803 by @​Gargron)
• Change streaming server to use its own dependencies and its own docker image (#​24702, #​27967, #​26850, #​28112, #​28115, #​28137, #​28138, #​28497, #​28548, #​30795, #​31612, and #​31615 by @​TheEssem, @​ThisIsMissEm, @​jippi, @​renchap, @​timetinytim, and @​vmstan)
  In order to reduce the amount of runtime dependencies, the streaming server has been moved into a separate package and Docker image.
  The mastodon image does not contain the streaming server anymore, as it has been moved to its own mastodon-streaming image.
  Administrators may need to update their setup accordingly.

• Change external links in the admin audit log to plain text or local administration pages (#​27139 and #​27150 by @​ClearlyClaire and @​ThisIsMissEm)
• Change YJIT to be enabled when available (#​30310 and #​27283 by @​ClearlyClaire and @​mjankowski)
  Enable Ruby's built-in just-in-time compiler. This improves performances substantially, at the cost of a slightly increased memory usage.
• Change .env file loading from deprecated dotenv-rails gem to dotenv gem (#​29173 and #​30121 by @​mjankowski)
  This should have no effect except in the unlikely case an environment variable included a newline.
• Change “Panjabi” language name to the more common spelling “Punjabi” (#​27117 by @​gunchleoc)
• Change encryption of OTP secrets to use ActiveRecord Encryption (#​29831, #​28325, #​30151, #​30202, #​30340, and #​30344 by @​ClearlyClaire and @​mjankowski)
  This requires a manual step from administrators of existing servers. Indeed, they need to generate new secrets, which can be done using bundle exec rails db:encryption:init.
  Furthermore, there is a risk that the introduced migration fails if the server was misconfigured in the past. If that happens, the migration error will include the relevant information.
• Change /api/v1/announcements to return regular Status entities (#​26736 by @​ClearlyClaire)
• Change imports to convert case-insensitive fields to lowercase (#​29739 and #​29740 by @​ThisIsMissEm)
• Change stats in the admin interface to be inclusive of the full selected range, from beginning of day to end of day (#​29416 and #​29841 by @​mjankowski)
• Change materialized views to be refreshed concurrently to avoid locks (#​29015 by @​Gargron)
• Change compose form to use server-provided post character and poll options limits (#​28928 and #​29490 by @​ClearlyClaire and @​renchap)
• Change streaming server logging from npmlog to pino and pino-http (#​27828 by @​ThisIsMissEm)
  This changes the Mastodon streaming server log format, so this might be considered a breaking change if you were parsing the logs.
• Change media “ALT” label to use a specific CSS class (#​28777 by @​ClearlyClaire)
• Change streaming API host to not be overridden to localhost in development mode (#​28557 by @​ClearlyClaire)
• Change cookie rotator to use SHA1 digest for new cookies (#​27392 by @​ClearlyClaire)
  Note that this requires that no pre-4.2.0 Mastodon web server is running when this code is deployed, as those would not understand the new cookies.
  Therefore, zero-downtime updates are only supported if you're coming from 4.2.0 or newer. If you want to skip Mastodon 4.2, you will need to completely stop Mastodon services before updating.
• Change preview card deletes to be done using batch method (#​28183 by @​vmstan)
• Change img-src and media-src CSP directives to not include https: (#​28025 and #​28561 by @​ClearlyClaire)
• Change self-destruct procedure (#​26439, #​29049, and #​29420 by @​ClearlyClaire and @​zunda)
  Instead of enqueuing deletion jobs immediately, tootctl self-destruct now outputs a value for the SELF_DESTRUCT environment variable, which puts a server in self-destruct mode, processing deletions in the background, while giving users access to their export archives.

Removed

• Remove unused E2EE messaging code and related crypto OAuth scope (#​31193, #​31945, #​31963, and #​31964 by @​ClearlyClaire and @​mjankowski)

• Remove setting for unfollow confirmation modal (#​29373 by @​ClearlyClaire)
  Instead, the unfollow confirmation modal will always be displayed.

Upgrade notes

To get the code for v4.3.0, use git fetch && git checkout v4.3.0.

[!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 changed since v4.2.12, with the Ruby, PostgreSQL and Node.js minimum version being higher. In addition, an optional dependency on libvips has been introduced to replace ImageMagick.

• Ruby: 3.1 or newer
• PostgreSQL: 12 or newer. PostgreSQL versions 14.0 to 14.3 are not supported as they contain a critical data-corruption bug (see below)
• 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: 18 or newer
• ImageMagick (optional if using libvips): 6.9.7-7 or newer
• libvips (optional, instead of ImageMagick): 8.13 or newer

PostgreSQL 14.0 to 14.3 bug

PostgreSQL versions 14.0 to 14.3 are not supported as they contain a critical data-corruption bug.

If you run one of those versions, please upgrade to the latest PostgreSQL 14 minor version (14.13 at the time of the release) before upgrading Mastodon. Upgrading a PostgreSQL without bumping the major version should only a require a restart of your database after your packages/containers have been updated, not any data migration.

If you are using Docker Compose to run PostgreSQL, please ensure that the image field does not specify the patch version (for example, it can be 14, or 14-alpine, to tell Docker to use the latest image with this tag), then:

• stop the database service: docker compose down db
• pull the latest version for this tag: docker compose pull db
• restart the service: docker compose up -d

If you want to use this opportunity to upgrade to a later PostgreSQL major version, then you will need to migrate your PostgreSQL data directory. You can find more informations about this process in the official documentation.

Active Record encryption secrets configuration

Mastodon now requires new environment variables for secret keys to be set.

Generate new secrets and set ACTIVE_RECORD_ENCRYPTION_DETERMINISTIC_KEY, ACTIVE_RECORD_ENCRYPTION_KEY_DERIVATION_SALT, and ACTIVE_RECORD_ENCRYPTION_PRIMARY_KEY accordingly before restarting Mastodon.

[!IMPORTANT] All Mastodon processes need to have access to the same secrets, so if you use multiple puma (mastodon-web) and sidekiq (mastodon-sidekiq) nodes, make sure to copy the secrets to all of them. Furthermore, these secrets should not be changed once set, as changing secrets is not supported and may cause data loss and other issues that are difficult to recover from.

Such secrets can be generated by running bin/rails db:encryption:init.

Docker image split

The official Docker image has now been split in two smaller images:

• ghcr.io/mastodon/mastodon, which does not contain the streaming server anymore
• ghcr.io/mastodon/mastodon-streaming, which contains only the streaming server

The docker-compose.yml file shipped with Mastodon has been updated accordingly. If you use something else, you will need to update your configuration.

Cookies and rolling updates

Cookies issued by Mastodon are now using SHA256 digests. To ensure you are not losing user sessions, do not perform a rolling update from versions of Mastodon earlier than v4.2.0.

That is, either completely stop Mastodon before updating it, or update to the latest v4.2 then update to v4.3.

Yarn 4 and corepack

We have switched from Yarn 1 to the more modern and more efficient Yarn 4.

The recommended way is to use corepack, which is normally distributed with NodeJS. To do so, do corepack enable, then, in Mastodon's directory, once you have checked out v4.3.0, corepack prepare.

You can also install yarn 4 directly if you don't want to or can't use corepack.

ImageMagick deprecation and libvips replacement

ImageMagick support in Mastodon is being deprecated in favor of libvips, a more efficient library to process image attachments.

To use libvips instead of ImageMagick, install libvips 8.13 or newer, and set the MASTODON_USE_LIBVIPS environment variable to true.

The official Mastodon docker images use libvips instead of ImageMagick, and we recommend you do the same, but ImageMagick is still supported in this version for older distributions that do not include a recent enough version of libvips.

StatsD removal and OpenTelemetry integration

StatsD support has been removed, after being deprecated in 4.2.0.

If you want to have metrics for your Sidekiq queues (queue size, latency…), you can use https://github.com/Strech/sidekiq-prometheus-exporter

Mastodon now also supports exporting tracing data using OpenTelemetry. This can be used to get detailed performance data, as well as monitoring for backend errors. More informations on how to configure it in our docs (https://docs.joinmastodon.org/admin/config/#otel)

Update steps

The following instructions are for updating from 4.2.12.

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-4.2 version, please check the “Cookies and rolling updates” section above.

If you are updating from 4.3.0-beta.1, 4.3.0-beta.2 or 4.3.0-rc.1, only a few of these steps are relevant, see the next section.

Non-docker

[!TIP] 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.

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 yarn 4 (if you use corepack, just do corepack prepare). See the “Yarn 4 and corepack” section for more information.
3. Install dependencies with bundle install and yarn install --immutable
4. Generate secrets by running RAILS_ENV=production bin/rails db:encryption:init, then copy them to your .env.production (copy it across all your nodes if you use multiple ones)
5. Precompile the assets: RAILS_ENV=production bundle exec rails assets:precompile
6. 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
7. Restart all Mastodon processes. If you are updating directly from a Mastodon version earlier than 4.2.0, see the “Cookies and rolling updates” section.
8. Run the post-deployment database migrations: RAILS_ENV=production bundle exec rails db:migrate
9. If you use Elasticsearch or OpenSearch, rebuild the account search index with RAILS_ENV=production bin/tootctl search deploy --only=accounts

When using docker

1. Generate secrets by running docker-compose run --rm web bin/rails db:encryption:init, then copy them to your .env.production (make sure to copy them across all your Mastodon nodes as they will all need access to these secrets)
2. 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
3. Make sure your Docker configuration has been updated to take the Docker image split into account (See the “Docker image split” section above)
4. Restart all Mastodon processes. If you are updating directly from a Mastodon version earlier than 4.2.0, see the “Cookies and rolling updates” section.
5. Run the post-deployment database migrations: docker-compose run --rm web bundle exec rails db:migrate
6. If you use Elasticsearch or OpenSearch, rebuild the account search index with docker-compose run --rm web bin/tootctl search deploy --only=accounts

Update steps from 4.3.0-beta.1, 4.3.0-beta.2 or 4.3.0-rc.1

The following instructions are for updating from 4.3.0-beta.1, 4.3.0-beta.2 or 4.3.0-rc.1, see the section above if you are updating from an older version.
