# Device Management Changelog
## The cl.distributedDeviceManager.1 API Change 

Added device management APIs in OpenHarmony 4.0.9.2.

**Change Impact**

The original [Device Management APIs](../../../application-dev/reference/apis/js-apis-device-manager.md) can still be used but will no longer be maintained. You are advised to use the new APIs for development.

**Key API/Component Changes**

The following APIs are added.
