# Resource Scheduler Subsystem ChangeLog

## cl.resourceschedule.backgroundTaskManager
 
Rectified original APIs of **backgroundTaskManager** of the resource scheduler subsystem. All APIs in API version 8 and earlier versions are deprecated, and original APIs in API version 9 are deleted. New APIs in API version 9 need to be used. The new APIs in API version 9 comply with the error code specifications.

**Change Impacts**

The application developed based on the SDK versions of OpenHarmony 3.2.8.2 and later needs to adapt the modules and APIs in API version 9 and their methods for returning API error information. Otherwise, the original service logic will be affected.

**Key API/Component Changes**

The following methods, attributes, enumerations, and constants are changed in API version 9 and later versions. The **@ohos.backgroundTaskManager.d.ts** file is deprecated and related APIs are migrated to the newly added **@ohos.resourceschedule.backgroundTaskManager.d.ts** file.

**Adaptation Guide**<br>

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).

## c3.resourceschedule.workScheduler
 
Rectified original APIs of **workScheduler** of the resource scheduler subsystem. The original APIs in API version 9 are changed to new APIs in API version 9. The new APIs in API version 9 comply with the error code specifications.

**Change Impacts**

The application developed based on the SDK versions of OpenHarmony 3.2.8.2 and later needs to adapt the modules and APIs in API version 9 and their methods for returning API error information. Otherwise, the original service logic will be affected.

**Key API/Component Changes**

The following methods, attributes, enumerations, and constants are changed in API version 9 and later versions. The **@ohos.workScheduler.d.ts** file is deprecated and related APIs are migrated to the newly added **@ohos.resourceschedule.workScheduler.d.ts** file.
