BREAKING-CHANGES.txt

 develop
 =======
 
+Change
+------
+The Projucer no longer automatically adds the iOS Inter-App Audio entitlement
+to AU hosts.
+
+Possible Issues
+----------------
+iOS AU hosts that rely upon Inter-App Audio will no longer be able to receive
+Inter-App Audio.
+
+Workaround
+----------
+Use the new "[Deprecated] AU Host Inter-App Audio Capability" option in the
+Projucer.
+
+Rationale
+---------
+Inter-App Audio is deprecated in iOS 13.
+
+
 Change
 ------
 Unique device IDs on Windows have been updated to use a more reliable SMBIOS
