 ## Unreleased
 
+## Added
+
 - Added a new configuration option to the MediaProxy feature that allows the blocking of specific domains from using the media proxy or being explicitly allowed by the Content-Security-Policy.
   - Please make sure instances you wanted to block media from are not in the MediaProxy `whitelist`, and instead use `blocklist`.
 - `OnlyMedia` Upload Filter to simplify restricting uploads to audio, image, and video types
 
+## Fixed
+
+- Deactivated users can no longer show up in the emoji reaction list
+- Embedded posts can no longer bypass `:restrict\_unauthenticated`
+
 ## 2023.05
 
 ## Added
