- Fix crash when supplying the `FFMPEG_BINARY` environment variable ([timothyjrogers](https://github.com/mastodon/mastodon/pull/30022))
- 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.

### Security
- Fix insufficient checking of remote posts ([GHSA-jhrq-qvrm-qr36](https://github.com/mastodon/mastodon/security/advisories/GHSA-jhrq-qvrm-qr36))
- 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))
- 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.

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).
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 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 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 Elasticsearch cluster health check and indexes mismatch check to dashboard** ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/26448), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26605), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26658))
- Add `hide_collections`, `discoverable` and `indexable` attributes to credentials API ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/26998))

- Add `DELETE /api/v1/profile/avatar` and `DELETE /api/v1/profile/header` to the REST API ([danielmbrasil](https://github.com/mastodon/mastodon/pull/25124), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26573))
- Add `ES_PRESET` option to customize numbers of shards and replicas ([Gargron](https://github.com/mastodon/mastodon/pull/26483), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/26489))
This can have a value of `single_node_cluster` (default), `small_cluster` (uses one replica) or `large_cluster` (uses one replica and a higher number of shards).
- Add client-side timeout on resend confirmation button ([Gargron](https://github.com/mastodon/mastodon/pull/26300))

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.
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`.
