OpenHarmony 4.0.3.2 has the following changes in the APIs of the pasteboard subsystem:
## cl.pasteboard.1 convertToTextV9 API Change
Renamed **convertToTextV9****toPlainText()** and changed the API from asynchronous to synchronous.
**Change Impact**
Applications developed using the **convertToTextV9** API in versions earlier than OpenHarmony 4.0.3.3 cannot be used in OpenHarmony 4.0.3.3 and later versions.
Replace **convertToTextV9**, an asynchronous API, with **toPlainText**, a synchronous API.
## cl.pasteboard.2 ShareOption Enum Name Change
Changed the enum names of **ShareOption** from UpperCamelCase to all caps.
**Change Impact**
Applications developed using the **InApp/LocalDevice/CrossDevice** attributes in versions earlier than OpenHarmony 4.0.3.3 cannot be used in OpenHarmony 4.0.3.3 and later versions.
**Key API/Component Changes**

| CROSSDEVICE | 2 | Paste is allowed in any application across devices. |
Changes that affect contract compatibility of the last version should be described in the changelog. The changes include but are not limited to those related to API names, parameters, return values, required permissions, call sequence, enumerated values, configuration parameters, and paths. The last version can be an LTS, release, beta, or monthly version, or the like. Contract compatibility, also called semantic compatibility, means that the original program behavior should remain consistent over versions.
## cl.subsystemname.x xxx Function Change (Example: DeviceType Attribute Change or Camera Permission Change. Use a short description.)
Add the number **cl.*subsystemname*.*x*** before each change title, where **cl** is the abbreviation of changelog, *subsystemname* is the standard English name of the subsystem, and *x* indicates the change sequence number (starting from 1 in ascending order).
Describe the changes in terms of functions. Example: *n* and *m* of the *a* function are changed. Developers need to adapt their applications based on the change description.
If there is a requirement or design document corresponding to the change, attach the requirement number or design document number in the description.
**Change Impact**
Describe whether released APIs (JS or native APIs) are affected or API behavior is changed.
Describe whether available applications are affected, that is, whether an adaptation is required for building the application code in the SDK environment of the new version.
**Key API/Component Changes**
List the API/component changes involved in the function change.
**Adaptation Guide**
Provide guidance for developers on how to adapt their application to the changes to be compatible with the new version.
The rules for starting application components are changed in the following scenarios:
- Start an application component when the application is in the background.
- Start an invisible application component across applications.
- Start a ServiceAbility and DataAbility of the FA model across applications.
- Use the **startAbilityByCall** API.
You need to adapt your application.
**Change Impact**
If new rules are not adapted, application components cannot be started in the previous scenarios.
> **NOTE**
>
> Starting application components refers to any behavior starting or connecting to an ability.
>
> 1. Start an ability using APIs such as **startAbility**, **startServiceExtensionAbility**, and **startAbilityByCall**.
> 2. Connect to an ability using APIs such as **connectAbility**, **connectServiceExtensionAbility**, **acquireDataAbilityHelper**, and **createDataShareHelper**.
> 1. Starting an application component of the same application is also restricted by this rule.
> 2. For SDKs of API version 8 or earlier, starting a ServiceAbility and DataAbility is not restricted by this rule.
-**Starting an invisible application component across applications**
- Rule in OpenHarmony 3.2 Beta3:
- For applications whose APL is normal, invisible application components cannot be started across applications.
- Rule in OpenHarmony 3.2 Beta4:
- For all applications, starting an invisible application component across applications requires authentication. The following permissions must be configured:
-**Starting a ServiceAbility and DataAbility of the FA model across applications**
- Rule in OpenHarmony 3.2 Beta3:
- There is no restriction.
- Rule in OpenHarmony 3.2 Beta4:
- Associated startup must be configured for the provider of the ServiceAbility and DataAbility. Otherwise, they cannot be started across applications. (Associated startup cannot be configured for common applications.)
-**Using the startAbilityByCall API**
- Rule in OpenHarmony 3.2 Beta3:
- This is no restriction.
- Rule in OpenHarmony 3.2 Beta4:
- The **startAbilityByCall** API cannot be called by the same application.
- Calling the **startAbilityByCall** API across applications requires authentication. The following permissions must be configured:
-**Starting a ServiceAbility of the FA model across applications**
- Rule in OpenHarmony 3.2 Beta3:
- There is no restriction.
- Rule in OpenHarmony 3.2 Beta4:
- Associated startup needs to be configured for the provider of the ServiceAbility. Otherwise, the ServiceAbility cannot be started across applications. (Associated startup cannot be configured for common applications.)
- Configure associated startup as follows:
-```json
{
"bundleName": "",
"app_signature": ["xxxxxxxxxxxxxxxxxxx"],
"associatedWakeUp": true
}
```
## cl.ability.3 API Exception Handling Method Change
Certain APIs of the ability subsystem use service logic return values to indicate error information, which does not comply with the API error code specifications of OpenHarmony.
**Change Impact**
The application developed based on earlier versions needs to be adapted. Otherwise, the service logic will be affected.
**Key API/Component Changes**
For adaptation to the unified API exception handling mode, certain ability subsystem APIs are deprecated (original APIs in the following table) and corresponding new APIs in the following table are added. (In the following table, original APIs in API version 9 will be deleted, and APIs in API version 8 and earlier will be deprecated.) The newly added APIs support unified error code handling specifications and function the same as the original APIs.
Some functional APIs are added and some others are deprecated to:
1. Improve the usability of camera APIs.
2. Help you quickly understand camera APIs and use them for development.
3. Facilitate expansion of framework functions in later versions, and reduce coupling between framework modules.
You need to refer to the following change description to adapt your application.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
**Key API/Component Changes**
| Module | Class | Method/Attribute/Enum/Constant | Change Type|
console.log(`Promise returned with current exposure point : ${exposurePoint}`);
})
```
15. The **setMeteringPoint(point: Point, callback: AsyncCallback<void>): void;** and **setMeteringPoint(point: Point): Promise<void>;** APIs are added to **CaptureSession**.
The code snippet is as follows:
```
const Point1 = {x: 1, y: 1};
captureSession.setMeteringPoint(Point1,(err) => {
if (err) {
console.log(`Failed to set the exposure point ${err.message}`);
return ;
}
console.log('Callback returned with the successful execution of setMeteringPoint');
5. The **release(callback: AsyncCallback<void>): void;** and **release(): Promise<void>;** APIs in **PreviewOutput** are deprecated.
6. The **release(callback: AsyncCallback<void>): void;** and **release(): Promise<void>;** APIs in **PhotoOutput** are deprecated.
7. The **release(callback: AsyncCallback<void>): void;** and **release(): Promise<void>;** APIs in **VideoOutput** are deprecated.
8. The **getCameraId(callback: AsyncCallback<string>): void;** and **getCameraId(): Promise<string>;** APIs in **CameraInput** are deprecated.
9. The **getExposurePoint(callback: AsyncCallback<Point>): void;** and **getExposurePoint(): Promise<Point>;** APIs in **CameraInput** are deprecated.
10. The **setExposurePoint(exposurePoint: Point, callback: AsyncCallback<void>): void;** and **setExposurePoint(exposurePoint: Point): Promise<void>;** APIs in **CameraInput** are deprecated.
**Changed APIs**
1. In **CameraManager**, the return value of **getCameras** is changed from **Array<Camera>** to **Array<CameraDevice>**, and the API name is changed from **getCameras** to **getSupportedCameras**. Therefore, the **getCameras(callback: AsyncCallback<Array<Camera>>): void;** and **getCameras(): Promise<Array<Camera>>;** APIs are changed to **getSupportedCameras(callback: AsyncCallback<Array<CameraDevice>>): void** and **getSupportedCameras(): Promise<Array<CameraDevice>>;**.
console.log(`Promise returned with an array of supported cameras: ${cameras.length}`);
})
```
2. In **CameraManager**, the input parameter of **createCameraInput** is changed from **cameraId: string** to **camera: CameraDevice**. Therefore, the **createCameraInput(cameraId: string, callback: AsyncCallback<CameraInput>): void;** and **createCameraInput(cameraId: string): Promise<CameraInput>;** APIs are changed to **createCameraInput(camera: CameraDevice, callback: AsyncCallback<CameraInput>): void;** and **createCameraInput(camera: CameraDevice): Promise<CameraInput>;**.
console.log('Promise returned with the CameraInput instance');
})
```
3. In **CameraManager**, the input parameter **profile: Profile** is added to **createPreviewOutput** and the **profile** parameter is obtained by the **getSupportedOutputCapability** API. Therefore, the **createPreviewOutput(surfaceId: string, callback: AsyncCallback<PreviewOutput>): void;** and **createPreviewOutput(surfaceId: string): Promise<PreviewOutput>;** APIs are changed to **createPreviewOutput(profile: Profile, surfaceId: string, callback: AsyncCallback<PreviewOutput>): void;** and **createPreviewOutput(profile: Profile, surfaceId: string): Promise<PreviewOutput>;**.
The code snippet is as follows:
```
let profile = cameraoutputcapability.previewProfiles[0];
console.log('Promise returned with previewOutput created.');
})
```
4. In **CameraManager**, the input parameter **profile: Profile** is added to **createPhotoOutput** and the **profile** parameter is obtained by the **getSupportedOutputCapability** API. Therefore, the **CreatePhotoOutput(surfaceId: string, callback: AsyncCallback<PhotoOutput>): void;** and **CreatePhotoOutput(surfaceId: string): Promise<PhotoOutput>;** APIs are changed to **createPhotoOutput(profile: Profile, surfaceId: string, callback: AsyncCallback<PhotoOutput>): void;** and **createPhotoOutput(profile: Profile, surfaceId: string): Promise<PhotoOutput>;**.
The code snippet is as follows:
```
let profile = cameraoutputcapability.photoProfiles[0];
console.log('Promise returned with photoOutput created.');
})
```
5. In **CameraManager**, the input parameter **profile: Profile** is added to **createVideoOutput** and the **profile** parameter is obtained by the **getSupportedOutputCapability** API. Therefore, the **createVideoOutput(surfaceId: string, callback: AsyncCallback<VideoOutput>): void;** and **createVideoOutput(surfaceId: string): Promise<VideoOutput>;** APIs are changed to **createVideoOutput(profile: VideoProfile, surfaceId: string, callback: AsyncCallback<VideoOutput>): void;** and **createVideoOutput(profile: VideoProfile, surfaceId: string): Promise<VideoOutput>;**.
The code snippet is as follows:
```
let profile = cameraoutputcapability.videoProfiles[0];
console.log('Promise returned with videoOutput created.');
})
```
6. In **CameraManager**, the input parameter **metadataObjectTypes: Array<MetadataObjectType>** is added to **createMetadataOutput**, and the **metadataObjectTypes** parameter is obtained by the **getSupportedOutputCapability** API. Therefore, the **function createMetadataOutput(callback: AsyncCallback<MetadataOutput>): void;** and **function createMetadataOutput(): Promise<MetadataOutput>;** APIs are changed to **createMetadataOutput(metadataObjectTypes: Array<MetadataObjectType>, callback: AsyncCallback<MetadataOutput>): void;** and **createMetadataOutput(metadataObjectTypes: Array<MetadataObjectType>): Promise<MetadataOutput>;**.
The code snippet is as follows:
```
let metadataObjectTypes = cameraoutputcapability.supportedMetadataObjectTypes;
console.log('Promise returned with metadataOutput created.');
})
```
7. In **CameraManager**, **createCaptureSession** does not need to consider the context attribute. Therefore, the **createCaptureSession(context: Context, callback: AsyncCallback<CaptureSession>): void;** and **createCaptureSession(context: Context): Promise<CaptureSession>;** APIs are changed to **createCaptureSession(callback: AsyncCallback<CaptureSession>): void;** and **createCaptureSession(): Promise<CaptureSession>;**.
console.log('Promise returned with captureSession created.');
})
```
8. The type of the **camera** attribute of the **CameraStatusInfo** API is changed from **Camera** to **CameraDevice**.
9. In **CameraInput**, the input parameter **camera: CameraDevice** is added to the **on(type: 'error')** API. Therefore, the **on(type: 'error', callback: ErrorCallback<CameraInputError>): void;** API is changed to **on(type: 'error', camera: CameraDevice, callback: ErrorCallback<CameraInputError>): void;**.
12. The following enums are added to **ExposureMode**:
Enum: EXPOSURE_MODE_AUTO; initial value: changed from the default value to **1**
Enum: EXPOSURE_MODE_CONTINUOUS_AUTO; initial value: changed from the default value to **2**
13. The following enums are added to **VideoStabilizationMode**:
Enum: LOW; initial value: changed from the default value to **1**
Enum: MIDDLE; initial value: changed from the default value to **2**
Enum: HIGH; initial value: changed from the default value to **3**
Enum: AUTO; initial value: changed from the default value to **4**
14. In **CaptureSession**, the parameter of the **addOutput** API is changed from the original child class type (**PreviewOutput**, **PhotoOutput**, **VideoOutput**, and **MetadataOutput**) to the base class type (**CameraOutput**). After the change, the number of APIs is reduced from 8 to 2.
console.log('Promise returned with cameraOutput added.');
})
```
15. In **CaptureSession**, the parameter of the **removeOutput** API is changed from the original child class type (**PreviewOutput**, **PhotoOutput**, **VideoOutput**, and **MetadataOutput**) to the base class type (**CameraOutput**). After the change, the number of APIs is reduced from 8 to 2.
## cl.device_manager.1 Error Information Return Method Change of APIs
The device manager API uses service logic return values to indicate the error information, which does not comply with the API error code specifications of OpenHarmony. The following changes are made in API version 9 and later:
Asynchronous API: An error message is returned via **AsyncCallback** or the **error** object of **Promise**.
Synchronous API: An error message is returned via an exception.
**Change Impact**
The application developed based on earlier versions needs to adapt the method for returning API error information. Otherwise, the original service logic will be affected.
**Key API/Component Changes**
Error code processing is added for the following APIs:
- The event types passed to the **continuationManager.on** and **continuationManager.off** APIs do not comply with the OpenHarmony API specifications.
- The return value of **continuationManager.on** varies with the event type, which does not comply with the OpenHarmony API specifications.
The following changes have been made:
- Changed the event type **deviceConnect** to **deviceSelected** and **deviceDisconnect** to **deviceUnselected** in the **continuationManager.on** and **continuationManager.off** APIs.
- Changed the return value of **continuationManager.on** to **Callback<Array<ContinuationResult>>** for all events.
**Change Impact**
The application developed based on earlier versions needs to be adapted. Otherwise, the service logic will be affected.
## cl.DistributedManagerService.2 Adding DATASYNC Permission Verification to continuationManager APIs
In earlier versions, the **continuationManager** APIs do not verify the caller, which does not comply with the OpenHarmony API specifications.
Now, before using a **continuationManager** API, the caller must apply for the **ohos.permission.DISTRIBUTED_DATASYNC** permission.
**Change Impact**
The application developed based on earlier versions needs to apply for the **ohos.permission.DISTRIBUTED_DATASYNC** permission in advance. Otherwise, the service logic will be affected.
## cl.multimedia.media.001 Change of VideoRecorder APIs to System APIs
In the MR version, the formal **AVRecorder** APIs (integrating audio and video) will be provided for external use.
**VideoRecorder** APIs in API version 9 are changed to system APIs, which are available only to system users. In the future, **VideoRecorder** APIs will be deprecated after system users switch to **AVRecorder**.
**Change Impact**
If the **VideoRecorder** caller is not a system user, the call will fail.
Involved APIs and enums:
function createVideoRecorder(callback: AsyncCallback<VideoRecorder>): void;
function createVideoRecorder(): Promise<VideoRecorder>;
## cl.multimedia.media.002 No Externally Provided Bit Rate Selection API in VideoPlayer
In API version 9, **VideoPlayer** does not externally provide the bit rate selection API. Such an API will be provided by **AVPlayer** in the MR version.
**Change Impact**
Bit rate selection cannot be performed in the multi-bit rate scenario of **VideoPlayer**. Relevant functions will be provided by **AVPlayer**.
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 Impact**
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, enums, and constants are changed in API version 9 and later versions. The **@ohos.backgroundTaskManager.d.ts** file is deprecated and related APIs are moved to the newly added **@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).
## c2.resourceschedule.usageStatistics
Rectified original APIs of **deviceUsageStatistics** 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 Impact**
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**

Released JS APIs are affected. The application needs to adapt these APIs so that it can be properly compiled in the SDK environment of the new version.
**Key API/Component Changes**
| OpenHarmony 3.2.8.1 API | OpenHarmony 3.2.9.1 SP8 API |
Changes that affect contract compatibility of the last version should be described in the changelog. The changes include but are not limited to those related to API names, parameters, return values, required permissions, call sequence, enumerated values, configuration parameters, and paths. The last version can be an LTS, release, beta, or monthly version, or the like. Contract compatibility, also called semantic compatibility, means that the original program behavior should remain consistent over versions.
## cl.subsystemname.x xxx Function Change (Example: DeviceType Attribute Change or Camera Permission Change. Use a short description.)
Add the number **cl.*subsystemname*.*x*** before each change title, where **cl** is the abbreviation of changelog, *subsystemname* is the standard English name of the subsystem, and *x* indicates the change sequence number (starting from 1 in ascending order).
Describe the changes in terms of functions. Example: *n* and *m* of the *a* function are changed. Developers need to adapt their applications based on the change description.
If there is a requirement or design document corresponding to the change, attach the requirement number or design document number in the description.
**Change Impact**
Describe whether released APIs (JS or native APIs) are affected or API behavior is changed.
Describe whether available applications are affected, that is, whether an adaptation is required for building the application code in the SDK environment of the new version.
**Key API/Component Changes**
List the API/component changes involved in the function change.
**Adaptation Guide**
Provide guidance for developers on how to adapt their application to the changes to be compatible with the new version.
The **requestPermissionsFromUser** API of **UIAbilityContext** is migrated from the ability subsystem to the security subsystem.
Previously, the permission popup was implemented based on **UIAbility**, which used the **startAbilityForResult** API of **UIAbilityContext** to return the permission authorization result to the caller. Therefore, **requestPermissionsFromUser** was temporarily placed in **UIAbilityContext**. The permission popup is now implemented based on **ServiceExtensionAbility**, which no longer requires **startAbilityForResult** of **UIAbilityContext**. Therefore, **requestPermissionsFromUser** is migrated to the security subsystem.
You need to adapt your application based on the following information.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
**Key API/Component Changes**

- @ohos.wantAgent.d.ts
-**TriggerInfo** and **WantAgentInfo** are deleted. Use the classes with the same name in **@ohos.app.ability.wantAgent.d.ts**.
**Adaptation Guide**
As mentioned above, only several APIs have their names changed in terms of, for example, the registration callbacks (**registerAbilityLifecycleCallback**, **unregisterAbilityLifecycleCallback**, **registerEnvironmentCallback**, and **unregisterEnvironmentCallback**) and connection and disconnection **ServiceExtensionAbility** (**connectAbility**, **connectAbilityWithAccount**, and **disconnectAbility**). For such APIs, replace their names with those of their corresponding new APIs in the lifecycle callbacks.
Most APIs are moved to the new namespace. Therefore, you can modify **import** for adaptation.
For example, the original API uses **@ohos.application.Ability**:
```js
importAbilityfrom'@ohos.application.Ability';
```
You can directly modify **import** to switch to the new namespace:
```js
importAbilityfrom'@ohos.app.ability.UIAbility';
```
In addition, exception handling is needed. For details, see the API reference for the new APIs.
## cl.ability.2 RestartFlag Attribute Names Changed and Unsupported Attribute Deleted in appRecovery
In the **appRecovery** API, the enum names of **RestartFlag** are changed from **NO_RESTART** upon a specific fault to **RESTART** upon a specific fault.
The **CPP_CRASH_NO_RESTART** enum is deleted.
**Change Impact**
If your application uses the **CPP_CRASH_NO_RESTART**, **JS_CRASH_NO_RESTART**, or **APP_FREEZE_NO_RESTART** attribute in versions earlier than 3.2.10.6, its behavior will change after an upgrade to 3.2.10.6.
1. All the APIs of the camera component are changed to system APIs in the API version 9.
2. Some functional APIs are added and some others are deprecated to:
Improve the usability of camera APIs.
Help you quickly understand camera APIs and use them for development.
Facilitate expansion of framework functions in later versions, and reduce coupling between framework modules.
You need to refer to the following change description to adapt your application.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
**Key API/Component Changes**

## cl.commonlibrary.1 Error Code and Information Change
The error codes and information returned by APIs of the **ArrayList**, **List**, **LinkedList**, **Stack**, **Queue**, **Deque**, **PlainArray**, **LightWeightMap**, **LightWeightSet**, **HashMap**, **HashSet**, **TreeMap**, and **TreeSet** classes are changed.
For details about the changed error codes, see [Utils Error Codes](../../../application-dev/reference/errorcodes/errorcode-utils.md).
No adaptation is required for applications developed using these APIs.
**Key API/Component Changes**
Error code information is redefined for APIs in these classes and marked using **'@throws'** in the *.d.ts file of the corresponding module.
The sample code is as follows:
**ArrayList** class before the change:
constructor();
**ArrayList** class after the change:
@throws { BusinessError } 10200012 - The ArrayList's constructor cannot be directly invoked.
The **MediaLibrary** class of the multimedia component is replaced by the **FilePicker** class.
**Change Impact**
For applications developed based on earlier versions, pay attention to the changes of APIs. **FilePicker** is a system application preset in OpenHarmony. You can use it to select and save files.
**Key API/Component Changes**
The APIs of **MediaLibrary**, located in **@ohos.multimedia.medialibrary**, are deprecated. The **FilePicker** class, located in [@ohos.file.picker](https://gitee.com/openharmony/interface_sdk-js/blob/master/api/@ohos.file.picker.d.ts) is used.
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**

**Adaptation Guide**<br>
If your application uses **getAbilityIcon** in **@ohos.bundle.bundleManager.d.ts**, replace it with **getMediaContent** in **@ohos.resourceManager.d.ts**. You need to obtain the icon ID in advance. For details, see [Usage Guide](../../../application-dev/reference/apis/js-apis-resource-manager.md#getmediacontent9).
## cl.bundlemanager.2 Bottom-Layer Capability Changed So That Only the System Resource HAP Supports Custom Permissions
Only the system resource HAP supports custom permissions. During HAP parsing, the bundle manager module parses the **definePermissions** field only in the configuration file of the resource HAP (bundle name: **ohos.global.systemres**), but not this field in other HAPs. This field is used to define permissions.
If an application requires custom permissions, add the permissions under the **definePermissions** field in the [configuration file](https://gitee.com/openharmony/utils_system_resources/blob/master/systemres/main/config.json) of the system resource HAP. For details about the permission format, see [Defining Permissions](../../../application-dev/quick-start/module-structure.md#internal-structure-of-the-definepermissions-attribute).
**Change Impact**<br>
After an upgrade to the new version image, the custom permission of the application does not take effect, and the authorization fails.
**Key API/Component Changes**<br>
The bottom-layer capability of the bundle manager module is changed. Only the system resource HAP supports custom permissions.
**Adaptation Guide**<br>
If an application requires custom permissions, add the permissions under the **definePermissions** field in the [configuration file](https://gitee.com/openharmony/utils_system_resources/blob/master/systemres/main/config.json) of the system resource HAP. For details about the permission format, see [Defining Permissions](../../../application-dev/quick-start/module-structure.md#internal-structure-of-the-definepermissions-attribute).
To sum up, except **packInfo**, which is changed to **BundlePackInfo**, the other file names are changed to start with uppercase letters.
**Change Impact**<br>
The change of the level-2 module file names does not affect the use of the level-1 module. If a level-2 module interface under **bundleManager** is directly imported to the .ts file and an error is reported during compilation on DevEco Studio, you must change the name of the imported file.
**Key API/Component Changes**<br>
The .d.ts file names in the **bundleManager** folder are changed to their respective API names in the file.
**Adaptation Guide**<br>
Generally, no adaptation is required. If a file in the **bundleManager** folder is directly imported to the application, you must change the imported file name as follows:

The **atomicServiceModuleType** field is deleted from the [HapModuleInfo](https://gitee.com/openharmony/interface_sdk-js/blob/master/api/bundleManager/HapModuleInfo.d.ts) struct.
**Adaptation Guide**<br>
Record the setting of the **atomicServiceModuleType** field, delete it from the [HapModuleInfo](https://gitee.com/openharmony/interface_sdk-js/blob/master/api/bundleManager/HapModuleInfo.d.ts) struct, and set the **moduleType** field in the [HapModuleInfo](https://gitee.com/openharmony/interface_sdk-js/blob/master/api/bundleManager/HapModuleInfo.d.ts) struct to the recorded value.
The data type of the **parameters** attribute value is changed. Specifically, the number, string, and boolean types are supported, but the any type is not.
**Change Impact**
For applications developed based on OpenHarmony3.2.10.7 and later SDK versions, the **parameters** attribute value can use the number, string, and boolean types only. If it uses the any type, a compilation error is reported.
**Key API/Component Changes**
The **parameters** attribute in @ohos.resourceschedule.workScheduler.d.ts is changed.
| Class| API Type| Statement Before the Change| Statement After the Change|
| -- | -- | -- | -- |
| workScheduler.WorkInfo | field | parameters?: {[key: string]: any} | parameters?: {[key: string]: number | string | boolean} |
**Adaptation Guide**
The **parameters** attribute uses the {[key: string]: number | string | boolean} data type.
Compared with OpenHarmony 3.2 Beta4, OpenHarmony 3.2.10.7(MR) has the following API changes in the util subsystem.
## cl.util.1. randomUUID Name Changed
The **randomUUID** function name is changed to **generateRandomUUID**.
Before change: function randomUUID(entropyCache?: boolean): string <br>After change: function generateRandomUUID(entropyCache?: boolean): string
You need to adapt your application.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
| @ohos.util | function randomUUID(entropyCache?: boolean): string | Deleted |
| @ohos.util | function generateRandomUUID(entropyCache?: boolean): string| Added |
**Adaptation Guide**
Refer to the code snippet below to call **generateRandomUUID** in your application.
Example:
```ts
importutilfrom'@ohos.util'
letuuid=util.generateRandomUUID(true);
console.log("RFC 4122 Version 4 UUID:"+uuid);
// Output:
// RFC 4122 Version 4 UUID:88368f2a-d5db-47d8-a05f-534fab0a0045
```
## cl.util.2 randomBinaryUUID Name Changed
The **randomBinaryUUID** function name is changed to **generateRandomBinaryUUID**.
Before change: function randomBinaryUUID(entropyCache?: boolean): Uint8Array<br>After change: function generateRandomBinaryUUID(entropyCache?: boolean): Uint8Array
You need to adapt your application.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
## cl.util.3. contains Parameter Type in the LRUCache Class Changed
The **contains** parameter type in the LRUCache class is changed from **object** to **K**.
Before change: contains(key: object): boolean <br>After change: contains(key: K): boolean
You need to adapt your application.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
