-# Setting Atomic Services to Support Sharing
-## How to Develop
-
-1. An application calls [UIAbility.onShare()](../reference/apis/js-apis-app-ability-uiAbility.md#onshare), a lifecycle callback provided by the UIAbility component, to set the data to share. In this lifecycle callback, **ohos.extra.param.key.contentTitle** indicates the title of the content to share in the sharing box, **ohos.extra.param.key.shareAbstract** provides an abstract description of the content, and **ohos.extra.param.key.shareUrl** indicates the online address of the service. You need to set these three items as objects, with the key set to **title**, **abstract**, and **url**, respectively.
-
-   ```ts
-   import AbilityConstant from '@ohos.app.ability.AbilityConstant';
-   class MyUIAbility extends UIAbility {
-       onShare(wantParams) {
-           console.log('onShare');
-           wantParams['ohos.extra.param.key.contentTitle'] = {title: "OA"};
-           wantParams['ohos.extra.param.key.shareAbstract'] = {abstract: "communication for company employee"};
-           wantParams['ohos.extra.param.key.shareUrl'] = {url: "oa.example.com"};
-       }
-   }
-   ```
-
-2. A system dialog box calls [abilityManager.acquireShareData()](../reference/apis/js-apis-app-ability-abilityManager.md#acquiresharedata) to obtain data shared through atomic service sharing. Specifically, the system finds the UIAbility based on the mission ID and calls the **OnShare()** lifecycle of the UIAbility to obtain the shared data.
-
-   ```ts
-   import abilityManager from '@ohos.app.ability.abilityManager';
-   try {
-       abilityManager.acquireShareData(1, (err, wantParam) => {
-           if (err) {
-               console.error(`acquireShareData fail, err: ${JSON.stringify(err)}`);
-           } else {
-               console.log(`acquireShareData success, data: ${JSON.stringify(wantParam)}`);
-           }
-       });
-   } catch (paramError) {
-       console.error(`error.code: ${JSON.stringify(paramError.code)}, error.message: ${JSON.stringify(paramError.message)}`);
-   }
-   ```

+# @ohos.bluetooth.connection (Bluetooth connection Module)
+
+The **connection** module provides APIs for operating and managing Bluetooth.
+
+> **NOTE**
+>
+> The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+
+
+
+## Modules to Import
+
+```js
+import connection from '@ohos.bluetooth.connection';
+```
+
+
+## connection.pairDevice<a name="pairDevice"></a>
+
+pairDevice(deviceId: string, callback: AsyncCallback&lt;void&gt;): void
+
+Pairs a Bluetooth device. This API uses an asynchronous callback to return the result.
+
+**Required permissions**: ohos.permission.ACCESS_BLUETOOTH
+
+**System capability**: SystemCapability.Communication.Bluetooth.Core
+
+**Parameters**
+
+| Name     | Type    | Mandatory  | Description                                 |

+# @ohos.resourceschedule.deviceStandby (Device Standby)
+A device enters standby mode if it is unused for a long period of time or after the Power button is pressed. The standby mode prolongs the battery life without affecting the use of applications. The **deviceStandby** module provides APIs for you to check whether a device is in standby mode and request or cancel standby resource control for an application.
+
+>  **NOTE**
+>   
+> The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+
+## Modules to Import

+```js
+import deviceStandby from '@ohos.resourceschedule.deviceStandby';
+```
+
+## deviceStandby.getExemptedApps
+
+getExemptedApps(resourceTypes: number, callback: AsyncCallback<Array&lt;ExemptedAppInfo&gt;>): void;

+## cl.accessToken.1 Change of the Media and Files Permission Group
 The original Media and File permission group contains the following permissions:
 - ohos.permission.MEDIA_LOCATION
 - ohos.permission.READ_MEDIA
 - ohos.permission.WRITE_MEDIA
 
 Changed the permission group as follows:
-- Added **ohos.permission.MEDIA_LOCATION** to the Image and Video permission group.
-- Added **ohos.permission.READ_MEDIA** and **ohos.permission.WRITE_MEDIA** to the File permission group.
+- Added **ohos.permission.MEDIA_LOCATION** to the Images and Video permission group.
+- Added **ohos.permission.READ_MEDIA** and **ohos.permission.WRITE_MEDIA** to the Documents permission group.
 
 
 **Change Impact**
 
-The permission dialog boxes are displayed by permission group.
+The dialog box for requesting permissions is displayed by permission group.
 
-- Before the change, if the three permissions are applied for an application, a dialog box for applying for the media and file permissions will be displayed only once.
-- After the change, if the three permissions are applied for an application, a dialog box for applying for the image and video permissions and a dialog box for applying for the file permission will be displayed.

+## cl.accessToken.2 Change of the Permission Requesting Modes of the Telephony, Messaging, and Call Logs Permission Groups
+The permissions of the Telephony, Messaging, and Call Logs permission groups are available only to system applications. The three permission groups contain the following permissions:
+- ohos.permission.ANSWER_CALL
+- ohos.permission.MANAGE_VOICEMAIL

+To enable third-party application developers to apply for these permissions, the method for requesting these permissions is changed to pre-authorization mode.

+# @ohos.app.ability.UIExtensionContentSession (带界面扩展能力界面操作类)
+
+UIExtensionContentSession是[UIExtensionAbility](js-apis-app-ability-uiExtensionAbility.md)加载界面内容时创建的实例对象，当UIExtensionComponent控件拉起指定的UIExtensionAbility时，UIExtensionAbility会创建UIExtensionContentSession对象，并通过[onSessionCreate](js-apis-app-ability-uiExtensionAbility.md#uiextensionabilityonsessioncreate)回调传递给开发者。一个UIExtensionComponent控件对应一个UIExtensionContentSession对象，提供界面加载，结果通知等方法。每个UIExtensionAbility的UIExtensionContentSession之间互不影响，可以各自进行操作。

+基于OpenHarmony4.0.9.3及之后的SDK版本开发的应用，setDistributedTables接口入参type类型由number变为DistributedType。
+
+**关键接口/组件变更**
+
+修改前setDistributedTables接口：
+
+ ```ts
+setDistributedTables(tables: Array<string>, type: number, config: DistributedConfig, callback: AsyncCallback<void>): void;
+setDistributedTables(tables: Array<string>, type?: number, config?: DistributedConfig): Promise<void>;
+ ```
+
+修改后setDistributedTables接口：
+
+ ```ts
+setDistributedTables(tables: Array<string>, type: DistributedType, config: DistributedConfig, callback: AsyncCallback<void>): void;
+setDistributedTables(tables: Array<string>, type?: DistributedType, config?: DistributedConfig): Promise<void>;
+ ```
