 ### 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.
