 ### Changed
 
+- ⚠️ Updated `SmallWebRTCTransport` to align with how other transports handle 
+  `on_client_disconnected`. Now, when the connection is closed and no reconnection 
+  is attempted, `on_client_disconnected` is called instead of `on_client_close`. The 
+  `on_client_close` callback is no longer used, use `on_client_disconnected` instead.
+
+- Check if `PipelineTask` has already been cancelled.
+
+- Don't raise an exception if event handler is not registered.

 - Upgraded `deepgram-sdk` to 4.1.0.

 ### Fixed
 
+- Fixed a `DailyTransport` issue that was not allow capturing video frames if

 - Fixed a `DeegramSTTService` connection issue when the user provided their own

 ### Other
 
+- It is now possible to run all (or most) foundational example with multiple
+  transports. By default, they run with P2P (Peer-To-Peer) WebRTC so you can try
+  everything locally. You can also run them with Daily or even with a Twilio
+  phone number.
+
 - Added foundation examples `07y-interruptible-minimax.py` and
   `07z-interruptible-sarvam.py`to show how to use the `MiniMaxHttpTTSService`
   and `SarvamTTSService`, respectively.
