# 设备管理ChangeLog
## cl.distributedDeviceManager.1 接口变更

从Openharmony 4.0.9.2版本开始，新增设备管理接口。

**变更影响**

原有的接口[API参考](../../../application-dev/reference/apis/js-apis-device-manager.md)暂时可继续使用，但是停止维护，建议使用新接口进行开发。

**关键的接口/组件变更**

##新增接口如下:

| 模块名                                | 类名                | 新增接口声明                                                   |
