CHANGELOG.md

@@ -59,6 +59,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - Ability to define custom HTTP headers per each frontend
 - MRF (`NoEmptyPolicy`): New MRF Policy which will deny empty statuses or statuses of only mentions from being created by local users
 - New users will receive a simple email confirming their registration if no other emails will be dispatched. (e.g., Welcome, Confirmation, or Approval Required)
+- 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.
