 ### Changes
 
-Changed the default value of the audio capture mode in non-Dolby Voice conferences to [Standard](https://api-references.dolby.io/comms-sdk-flutter/dolbyio_comms_sdk_flutter/AudioCaptureMode.html#standard) with [high](https://api-references.dolby.io/comms-sdk-flutter/dolbyio_comms_sdk_flutter/NoiseReduction.html#high) noise reduction. This setting optimizes captured audio for speech by aggressively removing non-speech content. If you want to transmit non-stationary background sounds to a conference and create a more natural audio experience, you can set noise reduction to [low](https://api-references.dolby.io/comms-sdk-flutter/dolbyio_comms_sdk_flutter/NoiseReduction.html#low), which offers a similar experience as the default setting in previous releases. If you wish to transmit non-voice audio to a conference as well and use input device setting without any processing, use the [Unprocessed](https://api-references.dolby.io/comms-sdk-flutter/dolbyio_comms_sdk_flutter/AudioCaptureMode.html#unprocessed) mode.

+- The [current](https://api-references.dolby.io/comms-sdk-flutter/dolbyio_comms_sdk_flutter/ConferenceService/current.html) method now returns null when the user is not in a conference.
