 # Subscribing to State Changes of a Remote Object
 
+## Overview
+
 IPC/RPC allows you to subscribe to the state changes of a remote stub object. When the remote stub object dies, a death notification will be sent to your local proxy object. Such subscription and unsubscription are controlled by APIs. To be specific, you need to implement the **DeathRecipient** interface and the **onRemoteDied** API to clear resources. This callback is invoked when the process accommodating the remote stub object dies, or the device accommodating the remote stub object leaves the network. It is worth noting that these APIs should be called in the following order: The proxy object must first subscribe to death notifications of the stub object. If the stub object is in the normal state, the proxy object can cancel the subscription as required. If the process of the stub object exits or the device hosting the stub object goes offline, subsequent operations customized by the proxy object will be automatically triggered.
 
 ## When to Use

en/application-dev/connectivity/websocket-connection.md

 # WebSocket Connection
 
-## When to Use
+## Overview
 
 You can use WebSocket to establish a bidirectional connection between a server and a client. Before doing this, you need to use the **createWebSocket()** API to create a **WebSocket** object and then use the **connect()** API to connect to the server. If the connection is successful, the client will receive a callback of the **open** event. Then, the client can communicate with the server using the **send()** API. When the server sends a message to the client, the client will receive a callback of the **message** event. If the client no longer needs this connection, it can call the **close()** API to disconnect from the server. Then, the client will receive a callback of the **close** event.

 If coding specification issues or errors exist in the code of an application, the application may encounter unexpected errors, for example, uncaught exceptions or application lifecycle timeouts, while it is running. In such a case, the application may exit unexpectedly. Error logs, however, are usually stored on users' local storage, making it inconvenient to locate faults. With the APIs provided by the **errorManager** module, your application will be able to report related errors and logs to your service platform for fault locating before it exits.

 # Development of Application Event Logging
 
-## Introduction
+## Overview
 
 A traditional log system aggregates log information generated by all applications running on the entire device, making it difficult to identify key information in the log. Therefore, an effective logging mechanism is needed to evaluate mission-critical information, for example, number of visits, number of daily active users, user operation habits, and key factors that affect application usage.

 The hiTraceChain module provides APIs to implement call chain tracing throughout a service process. This can help you quickly obtain the run log for the call chain of a specified service process and locate faults in inter-device, inter-process, or inter-thread communications.

+### Unrecommended: Using @StorageLink to Implement Event Notification
+
+Compared with the common mechanism for event notification, the two-way synchronization mechanism of @StorageLink and AppStorage is far less cost efficient and therefore not recommended. This is because AppStorage stores UI-related data, and its changes will cause costly UI refresh.
+
+In the following example, any tap event in the **TapImage** component will trigger a change of the **tapIndex** attribute. As @StorageLink establishes a two-way data synchronization with AppStorage, the local change is synchronized to AppStorage. As a result, all visible custom components owning the **tapIndex** attribute bound to AppStorage are notified to refresh the UI.

-The **workScheduler** module provides the APIs for registering, canceling, and querying deferred tasks.
-
-The system schedules and executes deferred tasks at an appropriate time, subject to the storage space, power consumption, temperature, and more.
+The **workScheduler** module provides the APIs for registering, canceling, and querying deferred tasks. You can use the APIs to register tasks that do not have high requirements on real-time performance as deferred tasks. The system schedules and executes the deferred tasks at an appropriate time, subject to the storage space, power consumption, and more.
 
 >  **NOTE**
 >
 >  - The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+>
 >  - The APIs of this module can be used only in the stage model.

+# Network Management Subsystem Changelog
+
+## request2 API Name Change
+
+Changed the name of the HTTP streaming request from **request2** to **requestInStream**. The original name **request2** does not clearly express the intent of the API and may cause ambiguity, which does not comply with the OpenHarmony API specifications. 
+ 
+  -  
+
+## dataProgress Event Name Change
+
+Changed the name of the streaming data receiving event from **dataProgress** to **dataReceiveProgress**. The original name **dataProgress** does not clearly express the meaning of the event, which does not comply with the OpenHarmony API specifications. 
+ 
+  -  
+
+**Change Impact**
+
+For applications developed based on earlier versions, the corresponding API and event names must be updated. Otherwise, API calls may fail, affecting the service logic.
+
+**Key API/Component Changes**
+
+Involved APIs:
+
+  - request2;
+  - on(type: "dataProgress", callback: Callback<{ receiveSize: number, totalSize: number }>): void;
+  - off(type: "dataProgress", callback: Callback<{ receiveSize: number, totalSize: number }>): void;

+  - request2(url: string, options: HttpRequestOptions, callback: AsyncCallback<number>): void;
+  - request2(url: string, options?: HttpRequestOptions): Promise<number>;
+  - on(type: "dataProgress", callback: Callback<{ receiveSize: number, totalSize: number }>): void;
+  - off(type: 'dataProgress', callback?: Callback<{ receiveSize: number, totalSize: number }>): void;
