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))

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))

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).

- **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 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.
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`.
