 ### ✅ Added
 - CallKit availability policies allows you to control wether `Callkit` should be enabled/disabled based on different rules [#611](https://github.com/GetStream/stream-video-swift/pull/611)
+- Codec negotiation during calls (#606)(https://github.com/GetStream/stream-video-swift/pull/606)
 
 ### 🐞 Fixed
 - By observing the `CallKitPushNotificationAdapter.deviceToken` you will be notified with an empty `deviceToken` value, once the object unregister push notifications. [#608](https://github.com/GetStream/stream-video-swift/pull/608)
