+## 2.4.0 - 2021-08-08
+
 ### Changed
 
+- **Breaking:** Configuration: `:chat, enabled` moved to `:shout, enabled` and `:instance, chat_limit` moved to `:shout, limit`
+- **Breaking** Entries for simple_policy, transparency_exclusions and quarantined_instances now list both the instance and a reason.
+- Support for Erlang/OTP 24
 - The `application` metadata returned with statuses is no longer hardcoded. Apps that want to display these details will now have valid data for new posts after this change.
 - HTTPSecurityPlug now sends a response header to opt out of Google's FLoC (Federated Learning of Cohorts) targeted advertising.
+- Email address is now returned if requesting user is the owner of the user account so it can be exposed in client and FE user settings UIs.
+- Improved Twittercard and OpenGraph meta tag generation including thumbnails and image dimension metadata when available.
+- AdminAPI: sort users so the newest are at the top.
+- ActivityPub Client-to-Server(C2S): Limitation on the type of Activity/Object are lifted as they are now passed through ObjectValidators
 
 ### Added
 
 - MRF (`FollowBotPolicy`): New MRF Policy which makes a designated local Bot account attempt to follow all users in public Notes received by your instance. Users who require approving follower requests or have #nobot in their profile are excluded.
 - Return OAuth token `id` (primary key) in POST `/oauth/token`.
+- AdminAPI: return `created_at` date with users.
+- AdminAPI: add DELETE `/api/v1/pleroma/admin/instances/:instance` to delete all content from a remote instance.
+- `AnalyzeMetadata` upload filter for extracting image/video attachment dimensions and generating blurhashes for images. Blurhashes for videos are not generated at this time.
+- Attachment dimensions and blurhashes are federated when available.
+- Mastodon API: support `poll` notification.
+- Pinned posts federation
+- AdminAPI: allow moderators to manage reports, users, invites, and custom emojis
 
 ### Fixed
 - Don't crash so hard when email settings are invalid.
-- Display OpenGraph data on alternative notice routes.
+- Checking activated Upload Filters for required commands.
-
+- Remote users can no longer reappear after being deleted.
-## Unreleased (Patch)
+- Deactivated users may now be deleted.
-
+- Deleting an activity with a lot of likes/boosts no longer causes a database timeout.
-### Fixed
+- Mix task `pleroma.database prune_objects`
-
+- Fixed rendering of JSON errors on ActivityPub endpoints.
+- Linkify: Parsing crash with URLs ending in unbalanced closed paren, no path separator, and no query parameters
 - Try to save exported ConfigDB settings (migrate_from_db) in the system temp directory if default location is not writable.
 - Uploading custom instance thumbnail via AdminAPI/AdminFE generated invalid URL to the image
 - Applying ConcurrentLimiter settings via AdminAPI
 - User login failures if their `notification_settings` were in a NULL state.
 - Mix task `pleroma.user delete_activities` query transaction timeout is now :infinity
+- MRF (`SimplePolicy`): Embedded objects are now checked. If any embedded object would be rejected, its parent is rejected. This fixes Announces leaking posts from blocked domains.
 - Fixed some Markdown issues, including trailing slash in links.

+## OTP releases vs from-source installations
+
+There are two ways to install Pleroma. You can use OTP releases or do a from-source installation. OTP releases are as close as you can get to binary releases with Erlang/Elixir. The release is self-contained, and provides everything needed to boot it, it is easily administered via the provided shell script to open up a remote console, start/stop/restart the release, start in the background, send remote commands, and more. With from source installations you install Pleroma from source, meaning you have to install certain dependencies like Erlang+Elixir and compile Pleroma yourself.
