+- **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=`).

+  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.

+- **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))

+  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`.

+### MacOS
+
+To set up **MacOS** for native development, complete the following steps:
+
+- Install the latest stable Ruby version (use a Ruby version manager for easy installation and management of Ruby versions)
+- Run `brew install postgresql@14`
+- Run `brew install redis`
+- Run `brew install imagemagick`
+- Install Foreman or a similar tool (such as [overmind](https://github.com/DarthSim/overmind)) to handle multiple process launching.
+- Navigate to Mastodon's root directory and run `brew install nvm` then `nvm use` to use the version from .nvmrc
+- Run `corepack enable && yarn set version classic`
+- Run `bundle exec rails db:setup` (optionally prepend `RAILS_ENV=development` to target the dev environment)
+- Finally, run `overmind start -f Procfile.dev`
+
+### Docker
+
+For development with **Docker**, complete the following steps:
+
+- Install Docker Desktop
+- Run `docker compose -f .devcontainer/docker-compose.yml up -d`
+- Run `docker compose -f .devcontainer/docker-compose.yml exec app .devcontainer/post-create.sh`
+- Finally, run `docker compose -f .devcontainer/docker-compose.yml exec app foreman start -f Procfile.dev`
