# Resource Scheduler Subsystem ChangeLog

## cl.resourceschedule.backgroundTaskManager 
Rectified the original APIs of **backgroundTaskManager** of the resource scheduler subsystem. All APIs of API version 9 in the **@ohos.backgroundTaskManager.d.ts** file are deleted, and the APIs of API version 9 in the **@ohos.resourceschedule.backgroundTaskManager.d.ts** file are used. The new APIs in API version 9 comply with the error code specifications.

**Change Impacts**

If your application is developed based on the SDK versions of OpenHarmony 3.2.10.5 and later, adapt to the modules and APIs in API version 9 and the pattern for returning error codes. Otherwise, the service logic will be affected.

**Key API/Component Changes**

The following methods, attributes, enums, and constants are changed in API version 9 and later versions. All the APIs in the **@ohos.backgroundTaskManager.d.ts** file are migrated to the **@ohos.resourceschedule.backgroundTaskManager.d.ts** file.

**Adaptation Guide**

Import the **backgroundTaskManager** module.
```
import bundle form '@ohos.resourceschedule.backgroundTaskManager'
```
Exception handling also needs to be adapted. For details, see the [backgroundTaskManager API reference](../../../application-dev/reference/apis/js-apis-resourceschedule-backgroundTaskManager.md).
