+# ANS通知子系统ChangeLog

+## cl.notificationManager.1  接口名变更
+
+基于此前接口名定义不够规范，与其他功能类型的接口命名不一致，对此接口名进行变更。
+
+**变更影响**
+
+底层仍支持原接口功能，不影响4.0.2.3版本调用该接口的应用。
+
+**关键接口/组件变更**
+
+| 包名            | 旧接口                                                       | 新接口                                                       |
+| --------------- | ------------------------------------------------------------ | ------------------------------------------------------------ |
+| ohos.notificationManager.d.ts | **function** supportDoNotDisturbMode(callback: AsyncCallback<boolean>): **void**; | **function** isSupportDoNotDisturbMode(callback: AsyncCallback<boolean>): **void**; |
+| ohos.notificationManager.d.ts | **function** supportDoNotDisturbMode(): Promise<boolean>; | **function** isSupportDoNotDisturbMode(): Promise<boolean>; |
+
+**适配指导**
+
+按新的接口isSupportDoNotDisturbMode调用。
+
