+### Changed
+
+- Changed: Room expiration (`exp`) in `DailyRoomProperties` is now optional
+  (None) by default instead of automatically setting a 5-minute expiration
+  time. You must explicitly set expiration time if desired.
+
 ### Deprecated
 
 - `AWSTTSService` is now deprecated, use `PollyTTSService` instead.
