    This release provides users with more flexible in-ear monitoring audio adjustment options, supporting the ability to set the in-ear monitoring volume to four times the original volume by calling [setInEarMonitoringVolume](API/api_irtcengine_setinearmonitoringvolume.html).

-   This release optimizes the video dual-stream mode. In the low-quality video stream adaptive mode (`AutoSimulcastStream`), when the receiver requests a low-quality video stream by calling [setRemoteVideoStreamType](API/api_irtcengine_setremotevideostreamtype.html) or [setRemoteVideoStreamTypeEx](API/api_irtcengineex_setremotevideostreamtypeex.html), the sender now processes requests from all users, expanding beyond the previous restriction to broadcasters only. This change ensures that the audience requests for low-quality video streams are implemented, thus improving the flexibility and adaptability of the dual-stream mode.

    - This release optimizes the design of the [setZones](API/api_ibasespatialaudioengine_setzones.html) method, supporting the ability to set the `zones` parameter to `NULL`, indicating the clearing of all echo cancellation zones.
    - As of this release, it is no longer necessary to unsubscribe from the audio streams of all remote users within the channel before calling the [ILocalSpatialAudioEngine](API/class_ilocalspatialaudioengine.html) method.
