+## [4.3.1] - 2024-10-21
+
+### 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.
+
+### Fixed
+
+- Fix follow recommendation moderation page default language when using regional variant (#32580 by @ClearlyClaire)
+- Fix column-settings spacing in local timeline in advanced view (#32567 by @lindwurm)
+- Fix broken i18n in text welcome mailer tags area (#32571 by @mjankowski)
+- Fix missing or incorrect cache-control headers for Streaming server (#32551 by @ThisIsMissEm)
+- Fix only the first paragraph being displayed in some notifications (#32348 by @ClearlyClaire)
+- Fix reblog icons on account media view (#32506 by @tribela)
+- Fix Content-Security-Policy not allowing OpenStack SWIFT object storage URI (#32439 by @kenkiku1021)
+- Fix back arrow pointing to the incorrect direction in RTL languages (#32485 by @renchap)
+- Fix streaming server using `REDIS_USERNAME` instead of `REDIS_USER` (#32493 by @ThisIsMissEm)
+- Fix follow recommendation carrousel scrolling on RTL layouts (#32462 and #32505 by @ClearlyClaire)
+- Fix follow recommendation suppressions not applying immediately (#32392 by @ClearlyClaire)
+- Fix language of push notifications (#32415 by @ClearlyClaire)
+- Fix mute duration not being shown in list of muted accounts in web UI (#32388 by @ClearlyClaire)
+- Fix “Mark every notification as read” not updating the read marker if scrolled down (#32385 by @ClearlyClaire)
+- Fix “Mention” appearing for otherwise filtered posts (#32356 by @ClearlyClaire)
+- Fix notification requests from suspended accounts still being listed (#32354 by @ClearlyClaire)
+- Fix list edition modal styling (#32358 and #32367 by @ClearlyClaire and @vmstan)
+- Fix 4 columns barely not fitting on 1920px screen (#32361 by @ClearlyClaire)
+- Fix icon alignment in applications list (#32293 by @mjankowski)
+
+## [4.3.0] - 2024-10-08
+
+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](https://github.com/mastodon/mastodon/security/advisories/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.\
+  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/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

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

+
+- **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](https://docs.joinmastodon.org/entities/Notification/#relationship_severance_event).
+- **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, #30846, #31819, #31900 and #32188 by @Gargron, @mjankowski and @oneiros)\
+  This adds a mechanism to [highlight the author of news articles](https://blog.joinmastodon.org/2024/07/highlighting-journalism-on-mastodon/) shared on Mastodon.\
+  Articles hosted outside the fediverse can indicate a fediverse author with a meta tag:
+  ```html
+  <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](https://docs.joinmastodon.org/entities/Notification/#moderation_warning).
+- **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

+  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.\
+  See API documentation at https://docs.joinmastodon.org/entities/Instance/#api-versions
+- Add quick links to Administration and Moderation Reports from Web UI (#24838 by @ThisIsMissEm)
+- Add link to `/admin/roles` in moderation interface when changing someone's role (#31791 by @ClearlyClaire)

+- Add optional hints for server rules (#29539 and #29758 by @ClearlyClaire and @Gargron)\
+  Server rules can now be broken into a short rule name and a longer explanation of the rule.\
+  This adds a new [`hint` attribute](https://docs.joinmastodon.org/entities/Rule/#hint) to `Rule` entities in the REST API.
+- Add support for PKCE in OAuth flow (#31129 by @ThisIsMissEm)
+- Add CDN cache busting on media deletion (#31353 and #31414 by @ClearlyClaire and @tribela)

+- Add support for PKCE Extension in OmniAuth OIDC through the `OIDC_USE_PKCE` environment variable (#31131 by @ThisIsMissEm)
+- Add API endpoints for unread notifications count (#31191 by @ClearlyClaire)\
+  This adds the following REST API endpoints:

+- Add `MASTODON_SIDEKIQ_READY_FILENAME` environment variable to use a file for Sidekiq to signal it is ready to process jobs (#30971 and #30988 by @renchap)\
+  In the official Docker image, this is set to `sidekiq_process_has_started_and_will_begin_processing_jobs` so that Sidekiq will touch `tmp/sidekiq_process_has_started_and_will_begin_processing_jobs` to signal readiness.
+- Add `S3_RETRY_LIMIT` environment variable to make S3 retries configurable (#23215 by @smiba)
+- Add `S3_KEY_PREFIX` environment variable (#30181 by @S0yKaf)
+- Add support for multiple `redirect_uris` when creating OAuth 2.0 Applications (#29192 by @ThisIsMissEm)

+- Add Kashubian, Pennsylvania Dutch, Vai, Jawi Malay, Mohawk and Low German to posting languages (#26024, #26634, #27136, #29098, #27115, and #27434 by @EngineerDali, @HelgeKrueger, and @gunchleoc)
+- Add option to use native Ruby driver for Redis through `REDIS_DRIVER=ruby` (#30717 by @vmstan)
+- Add support for libvips in addition to ImageMagick (#30090, #30590, #30597, #30632, #30857, #30869, #30858 and #32104 by @ClearlyClaire, @Gargron, and @mjankowski)\
+  Server admins can now use libvips as a faster and lighter alternative to ImageMagick for processing user-uploaded images.\
+  This requires libvips 8.13 or newer, and needs to be enabled with `MASTODON_USE_LIBVIPS=true`.\
+  This is enabled by default in the official Docker images, and is intended to completely replace ImageMagick in the future.
+- Add validations to `Web::PushSubscription` (#30540 and #30542 by @ThisIsMissEm)
+- Add anchors to each authorized application in `/oauth/authorized_applications` (#31677 by @fowl2)

+- Add OpenTelemetry instrumentation (#30130, #30322, #30353, #30350 and #31998 by @julianocosta89, @renchap, @robbkidd and @timetinytim)\
+  See https://docs.joinmastodon.org/admin/config/#otel for documentation
+- Add API to get multiple accounts and statuses (#27871 and #30465 by @ClearlyClaire)\
+  This adds `GET /api/v1/accounts` and `GET /api/v1/statuses` to the REST API, see https://docs.joinmastodon.org/methods/accounts/#index and https://docs.joinmastodon.org/methods/statuses/#index

+- Add support for specifying custom CA cert for Elasticsearch through `ES_CA_FILE` (#29122 and #29147 by @ClearlyClaire)
+- Add groundwork for annual reports for accounts (#28693 by @Gargron)\
+  This lays the groundwork for a “year-in-review”/“wrapped” style report for local users, but is currently not in use.
+- Add notification email on invalid second authenticator (#28822 by @ClearlyClaire)
+- Add date of account deletion in list of accounts in the admin interface (#25640 by @tribela)
+- Add new emojis from `jdecked/twemoji` 15.0 (#28404 by @TheEssem)

+- Add VAPID public key to instance serializer (#28006 by @ThisIsMissEm)
+- Add support for serving JRD `/.well-known/host-meta.json` in addition to XRD host-meta (#32206 by @c960657)

+### Changed
+
+- **Change icons throughout the web interface** (#27385, #27539, #27555, #27579, #27700, #27817, #28519, #28709, #28064, #28775, #28780, #27924, #29294, #29395, #29537, #29569, #29610, #29612, #29649, #29844, #27780, #30974, #30963, #30962, #30961, #31362, #31363, #31359, #31371, #31360, #31512, #31511, #31525, #32153, and #32201 by @ClearlyClaire, @Gargron, @arbolitoloco1, @mjankowski, @nclm, @renchap, @ronilaukkarinen, and @zunda)\
+  This changes all the interface icons from FontAwesome to Material Symbols for a more modern look, consistent with the official Mastodon Android app.\
+  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](https://docs.joinmastodon.org/entities/Suggestion/#sources).
+- 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 how content warnings and filters are displayed in web UI (#31365, and #31761 by @Gargron)
+- Change preview card processing to ignore `undefined` as canonical url (#31882 by @oneiros)
+- Change embedded posts to use web UI (#31766, #32135 and #32271 by @Gargron)

+- Change zoom icon in web UI (#29683 by @Gargron)
+- Change directory page to use URL query strings for options (#31980, #31977 and #31984 by @ClearlyClaire and @renchap)

+- Change width of columns in advanced web UI (#31762 by @Gargron)
+- Change design of unread conversations in web UI (#31763 by @Gargron)
+- Change Web UI to allow viewing and severing relationships with suspended accounts (#27667 by @ClearlyClaire)\
+  This also adds a `with_suspended` parameter to `GET /api/v1/accounts/relationships` in the REST API.
+- Change preview card image size limit from 2MB to 8MB when using libvips (#31904 by @ClearlyClaire)
+- Change avatars border radius (#31390 by @renchap)

+- Change media to be hidden/blurred by default in report modal (#28522 by @ClearlyClaire)
+- Change order of the "muting" and "blocking" list options in “Data Exports” (#26088 by @fixermark)
+- Change admin and moderation notes character limit from 500 to 2000 characters (#30288 by @ThisIsMissEm)
+- Change mute options to be in dropdown on muted users list in web UI (#30049 and #31315 by @ClearlyClaire and @Gargron)
+- Change out-of-band hashtags design in web UI (#29732 by @Gargron)
+- Change design of metadata underneath detailed posts in web UI (#29585, #29605, and #29648 by @ClearlyClaire and @Gargron)
+- Change action button to be last on profiles in web UI (#29533 and #29923 by @ClearlyClaire and @Gargron)
+- Change confirmation prompts in trending moderation interface to be more specific (#19626 by @tribela)
+- Change “Trends” moderation menu to “Recommendations & Trends” and move follow recommendations there (#31292 by @ThisIsMissEm)
+- Change irrelevant fields in account cleanup settings to be disabled unless automatic cleanup is enabled (#26562 by @c960657)
+- Change dropdown menu icon to not be replaced by close icon when open in web UI (#29532 by @Gargron)
+- Change back button to always appear in advanced web UI (#29551 and #29669 by @Gargron)
+- Change border of active compose field search inputs (#29832 and #29839 by @vmstan)
+- Change instances of Nokogiri HTML4 parsing to HTML5 (#31812, #31815, #31813, and #31814 by @flavorjones)
+- Change link detection to allow `@` at the end of an URL (#31124 by @adamniedzielski)
+- Change User-Agent to use Mastodon as the product, and http.rb as platform details (#31192 by @ClearlyClaire)
+- Change layout and wording of the Content Retention server settings page (#27733 by @vmstan)
+- Change unconfirmed users to be kept for one week instead of two days (#30285 by @renchap)
+- Change maximum page size for Admin Domain Management APIs from 200 to 500 (#31253 by @ThisIsMissEm)
+- Change database pool size to default to Sidekiq concurrency settings in Sidekiq processes (#26488 by @sinoru)
+- Change alt text to empty string for avatars (#21875 by @jasminjohal)
+- Change Docker images to use custom-built libvips and ffmpeg (#30571, #30569, and #31498 by @vmstan)
+- 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 `CacheBuster` default options (#30718 by @mjankowski)
+- Remove home marker updates from the Web UI (#22721 by @davbeck)\
+  The web interface was unconditionally updating the home marker to the most recent received post, discarding any value set by other clients, thus making the feature unreliable.
+- Remove support for Ruby 3.0 (reaching EOL) (#29702 by @mjankowski)
+- Remove setting for unfollow confirmation modal (#29373 by @ClearlyClaire)\
+  Instead, the unfollow confirmation modal will always be displayed.
+- Remove support for Capistrano (#27295 and #30009 by @mjankowski and @renchap)

+`docker-compose.yml` in the project root directory.

- Install Docker Desktop
- Run `docker compose -f .devcontainer/docker-compose.yml up -d`
- Run `docker compose -f .devcontainer/docker-compose.yml exec app bin/setup`
- Finally, run `docker compose -f .devcontainer/docker-compose.yml exec app bin/dev`
+For local development, install and launch [Docker], and run:

-If you are using an IDE with [support for the Development Container specification](https://containers.dev/supporting), it will run the above `docker compose` commands automatically. For **Visual Studio Code** this requires the [Dev Container extension](https://containers.dev/supporting#dev-containers).
+```shell
+docker compose -f .devcontainer/compose.yaml up -d
+docker compose -f .devcontainer/compose.yaml exec app bin/setup
+docker compose -f .devcontainer/compose.yaml exec app bin/dev
+```
+
+### Dev Containers
+
+Within IDEs that support the [Development Containers] specification, start the
+"Mastodon on local machine" container from the editor. The necessary `docker
+compose` commands to build and setup the container should run automatically. For
+**Visual Studio Code** this requires installing the [Dev Container extension].
