# Device Management Changelog
## cl.device_manager.1 API Permission Change

Added permission verification for some APIs.

**Change Impact**

The apps developed using OpenHarmony 4.0.8.2 or later must have the corresponding permissions. Otherwise, the related APIs cannot be called.

Apply for the corresponding permissions for your application before these APIs are called.


## cl.device_manager.2 Permission Verification for All System APIs

Added permission verification for all system APIs.

**Change Impact**

Non-system applications and applications without system API permission cannot call system APIs.
