# Changelog
All notable changes to this project will be documented in this file.
## [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.

## [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
- `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](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
- **Add ability to reorder uploaded media before posting in web UI** (#28456 and #32093 by @Gargron)

- Add ability for admins to configure instance favicon and logo (#30040, #30208, #30259, #30375, #30734, #31016, and #30205 by @ClearlyClaire, @FawazFarid, @JasonPunyon, @mgmn, and @renchap)\
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 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 `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.

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.

### 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 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 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 StatsD integration (replaced by OpenTelemetry) (#30240 by @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)

## [4.2.8] - 2024-02-23
### Added
- Add hourly task to automatically require approval for new registrations in the absence of moderators ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29318), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/29355))
In order to prevent future abandoned Mastodon servers from being used for spam, harassment and other malicious activity, Mastodon will now automatically switch new user registrations to require moderator approval whenever they are left open and no activity (including non-moderation actions from apps) from any logged-in user with permission to access moderation reports has been detected in a full week.
When this happens, users with the permission to change server settings will receive an email notification.
This feature is disabled when `EMAIL_DOMAIN_ALLOWLIST` is used, and can also be disabled with `DISABLE_AUTOMATIC_SWITCHING_TO_APPROVED_REGISTRATIONS=true`.
### Changed
- Change registrations to be closed by default on new installations ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29280))
If you are running a server and never changed your registrations mode from the default, updating will automatically close your registrations.
Simply re-enable them through the administration interface or using `tootctl settings registrations open` if you want to enable them again.
### Fixed
- Fix processing of remote ActivityPub actors making use of `Link` objects as `Image` `url` ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29335))
- Fix link verifications when page size exceeds 1MB ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29358))
## [4.2.7] - 2024-02-16
### Fixed
- Fix OmniAuth tests and edge cases in error handling ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29201), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/29207))
- Fix new installs by upgrading to the latest release of the `nsa` gem, instead of a no longer existing commit ([mjankowski](https://github.com/mastodon/mastodon/pull/29065))
### Security
- Fix insufficient checking of remote posts ([GHSA-jhrq-qvrm-qr36](https://github.com/mastodon/mastodon/security/advisories/GHSA-jhrq-qvrm-qr36))
## [4.2.6] - 2024-02-14
### Security
- Update the `sidekiq-unique-jobs` dependency (see [GHSA-cmh9-rx85-xj38](https://github.com/mhenrixon/sidekiq-unique-jobs/security/advisories/GHSA-cmh9-rx85-xj38))
In addition, we have disabled the web interface for `sidekiq-unique-jobs` out of caution.
If you need it, you can re-enable it by setting `ENABLE_SIDEKIQ_UNIQUE_JOBS_UI=true`.
If you only need to clear all locks, you can now use `bundle exec rake sidekiq_unique_jobs:delete_all_locks`.
- Update the `nokogiri` dependency (see [GHSA-xc9x-jj77-9p9j](https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-xc9x-jj77-9p9j))
- Disable administrative Doorkeeper routes ([ThisIsMissEm](https://github.com/mastodon/mastodon/pull/29187))
- Fix ongoing streaming sessions not being invalidated when applications get deleted in some cases ([GHSA-7w3c-p9j8-mq3x](https://github.com/mastodon/mastodon/security/advisories/GHSA-7w3c-p9j8-mq3x))
In some rare cases, the streaming server was not notified of access tokens revocation on application deletion.
- Change external authentication behavior to never reattach a new identity to an existing user by default ([GHSA-vm39-j3vx-pch3](https://github.com/mastodon/mastodon/security/advisories/GHSA-vm39-j3vx-pch3))
Up until now, Mastodon has allowed new identities from external authentication providers to attach to an existing local user based on their verified e-mail address.
This allowed upgrading users from a database-stored password to an external authentication provider, or move from one authentication provider to another.
However, this behavior may be unexpected, and means that when multiple authentication providers are configured, the overall security would be that of the least secure authentication provider.
For these reasons, this behavior is now locked under the `ALLOW_UNSAFE_AUTH_PROVIDER_REATTACH` environment variable.
In addition, regardless of this environment variable, Mastodon will refuse to attach two identities from the same authentication provider to the same account.
## [4.2.5] - 2024-02-01
### Security
- Fix insufficient origin validation (CVE-2024-23832, [GHSA-3fjr-858r-92rw](https://github.com/mastodon/mastodon/security/advisories/GHSA-3fjr-858r-92rw))

## [4.2.0] - 2023-09-21
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 [@danielmbrasil](https://github.com/danielmbrasil), [@mjankowski](https://github.com/mjankowski), [@nschonni](https://github.com/nschonni), [@renchap](https://github.com/renchap), and [@takayamaki](https://github.com/takayamaki).
### Added
- **Add full-text search of opted-in public posts and rework search operators** ([Gargron](https://github.com/mastodon/mastodon/pull/26485), [jsgoldstein](https://github.com/mastodon/mastodon/pull/26344), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26657), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26650), [jsgoldstein](https://github.com/mastodon/mastodon/pull/26659), [Gargron](https://github.com/mastodon/mastodon/pull/26660), [Gargron](https://github.com/mastodon/mastodon/pull/26663), [Gargron](https://github.com/mastodon/mastodon/pull/26688), [Gargron](https://github.com/mastodon/mastodon/pull/26689), [Gargron](https://github.com/mastodon/mastodon/pull/26686), [Gargron](https://github.com/mastodon/mastodon/pull/26687), [Gargron](https://github.com/mastodon/mastodon/pull/26692), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26697), [Gargron](https://github.com/mastodon/mastodon/pull/26699), [Gargron](https://github.com/mastodon/mastodon/pull/26701), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26710), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26739), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26754), [Gargron](https://github.com/mastodon/mastodon/pull/26662), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26755), [Gargron](https://github.com/mastodon/mastodon/pull/26781), [Gargron](https://github.com/mastodon/mastodon/pull/26782), [Gargron](https://github.com/mastodon/mastodon/pull/26760), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26756), [Gargron](https://github.com/mastodon/mastodon/pull/26784), [Gargron](https://github.com/mastodon/mastodon/pull/26807), [Gargron](https://github.com/mastodon/mastodon/pull/26835), [Gargron](https://github.com/mastodon/mastodon/pull/26847), [Gargron](https://github.com/mastodon/mastodon/pull/26834), [arbolitoloco1](https://github.com/mastodon/mastodon/pull/26893), [tribela](https://github.com/mastodon/mastodon/pull/26896), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26927), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26959), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/27014))
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](https://github.com/mastodon/mastodon/pull/26582))
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](https://github.com/mastodon/mastodon/pull/26484), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26508))
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](https://github.com/mastodon/mastodon/pull/26492), [arbolitoloco1](https://github.com/mastodon/mastodon/pull/26497), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26506), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26525), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26606), [Gargron](https://github.com/mastodon/mastodon/pull/26666), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26960))
- **Add role badges to the web interface** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/25649), [Gargron](https://github.com/mastodon/mastodon/pull/26281))
- **Add ability to pick domains to forward reports to using the `forward_to_domains` parameter in `POST /api/v1/reports`** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/25866), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26636))
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](https://github.com/mastodon/mastodon/pull/25341), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26189))
- 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](https://github.com/mastodon/mastodon/pull/26083), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26368), [CSDUMMI](https://github.com/mastodon/mastodon/pull/26857), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26901))
- **Add webhook templating** ([Gargron](https://github.com/mastodon/mastodon/pull/23289))
- **Add webhooks for local `status.created`, `status.updated`, `account.updated` and `report.updated`** ([VyrCossont](https://github.com/mastodon/mastodon/pull/24133), [VyrCossont](https://github.com/mastodon/mastodon/pull/24243), [VyrCossont](https://github.com/mastodon/mastodon/pull/24211))
- **Add exclusive lists** ([dariusk, necropolina](https://github.com/mastodon/mastodon/pull/22048), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/25324))
- **Add a confirmation screen when suspending a domain** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/25144), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/25603))
- **Add support for importing lists** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/25203), [mgmn](https://github.com/mastodon/mastodon/pull/26120), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26372))
- **Add optional hCaptcha support** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/25019), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/25057), [Gargron](https://github.com/mastodon/mastodon/pull/25395), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26388))

- **Change design of link previews in web UI** ([Gargron](https://github.com/mastodon/mastodon/pull/26136), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26151), [Gargron](https://github.com/mastodon/mastodon/pull/26153), [Gargron](https://github.com/mastodon/mastodon/pull/26250), [Gargron](https://github.com/mastodon/mastodon/pull/26287), [Gargron](https://github.com/mastodon/mastodon/pull/26286), [c960657](https://github.com/mastodon/mastodon/pull/26184))
- **Change "direct message" nomenclature to "private mention" in web UI** ([Gargron](https://github.com/mastodon/mastodon/pull/24248))
- **Change translation feature to cover Content Warnings, poll options and media descriptions** ([c960657](https://github.com/mastodon/mastodon/pull/24175), [S-H-GAMELINKS](https://github.com/mastodon/mastodon/pull/25251), [c960657](https://github.com/mastodon/mastodon/pull/26168), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26452))
- **Change account search to match by text when opted-in** ([jsgoldstein](https://github.com/mastodon/mastodon/pull/25599), [Gargron](https://github.com/mastodon/mastodon/pull/26378))
- **Change import feature to be clearer, less error-prone and more reliable** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/21054), [mgmn](https://github.com/mastodon/mastodon/pull/24874))
- **Change local and federated timelines to be tabs of a single “Live feeds” column** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/25641), [Gargron](https://github.com/mastodon/mastodon/pull/25683), [mgmn](https://github.com/mastodon/mastodon/pull/25694), [Plastikmensch](https://github.com/mastodon/mastodon/pull/26247), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26633))
- **Change user archive export to be faster and more reliable, and export `.zip` archives instead of `.tar.gz` ones** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/23360), [TheEssem](https://github.com/mastodon/mastodon/pull/25034))
- **Change `mastodon-streaming` systemd unit files to be templated** ([e-nomem](https://github.com/mastodon/mastodon/pull/24751))
- **Change `statsd` integration to disable sidekiq metrics by default** ([mjankowski](https://github.com/mastodon/mastodon/pull/25265), [mjankowski](https://github.com/mastodon/mastodon/pull/25336), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26310))
This deprecates `statsd` support and disables the sidekiq integration unless `STATSD_SIDEKIQ` is set to `true`.
This is because the `nsa` gem is unmaintained, and its sidekiq integration is known to add very significant overhead.
Later versions of Mastodon will have other ways to get the same metrics.
- **Change replica support to native Rails adapter** ([krainboltgreene](https://github.com/mastodon/mastodon/pull/25693), [Gargron](https://github.com/mastodon/mastodon/pull/25849), [Gargron](https://github.com/mastodon/mastodon/pull/25874), [Gargron](https://github.com/mastodon/mastodon/pull/25851), [Gargron](https://github.com/mastodon/mastodon/pull/25977), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26074), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26326), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26386), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26856))
This is a breaking change, dropping `makara` support, and requiring you to update your database configuration if you are using replicas.
To tell Mastodon to use a read replica, you can either set the `REPLICA_DB_NAME` environment variable (along with `REPLICA_DB_USER`, `REPLICA_DB_PASS`, `REPLICA_DB_HOST`, and `REPLICA_DB_PORT`, if they differ from the primary database), or the `REPLICA_DATABASE_URL` environment variable if your configuration is based on `DATABASE_URL`.
