 除新增接口，和废弃接口之外，开发者需要关注变更的接口的适配：
 
-**接口变更**
-
 从Beta4版本开始，对以下接口进行调整：
 
-1. CameraManager中接口getCameras返回值由Array<Camera>变更为Array<CameraDevice>，因此旧接口getCameras(callback: AsyncCallback<Array<Camera>>): void;以及getCameras(): Promise<Array<Camera>>;变更为getSupportedCameras(callback: AsyncCallback<Array<CameraDevice>>): void和getSupportedCameras(): Promise<Array<CameraDevice>>;
+**新增接口**
 
-   参考代码如下：
