@ -8,16 +8,23 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

 ### Changed

+- **Breaking:** Configuration: `:chat, enabled` moved to `:shout, enabled` and `:instance, chat_limit` moved to `:shout, limit`
+- 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.

 ### 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`.
+- `AnalyzeMetadata` upload filter for extracting attachment dimensions and generating blurhashes.
+- Attachment dimensions and blurhashes are federated when available.
+- Pinned posts federation

 ### Fixed
 - Don't crash so hard when email settings are invalid.
+- Checking activated Upload Filters for required commands.
 - Mix task `pleroma.database prune_objects`

 ## Unreleased (Patch)
@ -29,6 +36,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - 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.
