-If HiSysEvent logging is required for a component, you need to define a YAML file and [configure the YAML file path](#section123181432175135) in the **bundle.json** file. During compilation, the OpenHarmony compilation framework will use the Python compilation script to parse and verify all the YAML files configured in the **bundle.json** file. On completion, the compilation framework will summarize the configuration information in the YAML files and convert the information into a JSON file named **hisysevent.def**. After that, the compilation framework will put the JSON file to a specified path as the basis for the system to determine whether to log system events.

+
+### Function Introduction
+
+If HiSysEvent logging is required for a component, you need to define a YAML file and [configure the YAML file path](#configuring-the-yaml-file-path) in the **bundle.json** file. During compilation, the OpenHarmony compilation framework will use the Python compilation script to parse and verify all the YAML files configured in the **bundle.json** file. On completion, the compilation framework will summarize the configuration information in the YAML files and convert the information into a JSON file named **hisysevent.def**. After that, the compilation framework will put the JSON file to a specified path as the basis for the system to determine whether to log system events.
+
+
+### Basic Concepts
 
 Understanding the following concepts would be helpful for you in configuring HiSysEvent logging.
 
-- Event domain
-  Represents the domain to which an event belongs. It is specified by the **domain** field in the YAML file. For details, see [domain](#section123181432175123) in the example YAML file.
+- Event domain<br>Represents the domain to which an event belongs. It is specified by the **domain** field in the YAML file. For details, see [domain](#example) in the example YAML file.
 
-- Event name
-  Indicates the events in an event domain. For details, see [EVENT\_NAMEA/EVENT\_NAMEB](#section123181432175123) in the example YAML file.
+- Event name<br>Indicates the events in an event domain. For details, see [EVENT\_NAMEA/EVENT\_NAMEB](#example) in the example YAML file.
 
-- Parameter
-  Defines the key values in an event name. For details, see [__BASE/NAME1/NAME2](#section123181432175123) in the example YAML file.
+- Parameter<br>Defines the key values in an event name. For details, see [__BASE/NAME1/NAME2](#example) in the example YAML file.
 
 
-### Constraints<a name="section123181432175114"></a>
+### Constraints
+
+Constraints on the event domain, event name, and parameter
 
 - Each YAML file can contain only one event domain, and the domain name cannot be the same as that defined in other YAML files.
 
 - Zero or more event names can be defined for one event domain. The event names in the same event domain must be unique.
 
-- Multiple parameters can be defined for one event name. The parameters in the same event name must be unique. There must be one and only one parameter named **\__BASE** in each event name. See Table 1 for the fields of this parameter and Table 2 for the fields of other custom parameters.
-
-  **Table 1** Fields in the \__BASE parameter
+- Multiple parameters can be defined for one event name. The parameters in the same event name must be unique. There must be only one parameter named **__BASE** in each event name. See Table 1 for the fields of this parameter and Table 2 for the fields of other custom parameters.

+### Example
 
--   In the example YAML file, the event domain name is **MODULEA**. The event domain contains two events named **EVENT\_NAMEA** and **EVENT\_NAMEB**.
--   **EVENT\_NAMEA** is defined as a critical event of the fault type. The event contains the **NAME1** parameter of the string type, the **NAME2** parameter of the string type, and the **NAME3** parameter of the unsigned short integer type. Therefore, you can perform [real-time subscription](subsys-dfx-hisysevent-listening.md) to the event based on the event domain **MODULEA** and event name **EVENT\_NAMEA**.
--   **EVENT\_NAMEB** is defined as a general event of the statistics type. The event contains the **NAME1** parameter of the unsigned short integer type and the **NAME2** parameter of the integer type. Because two event tags named **tag1** and **tag2** are defined for **EVENT\_NAMEB** in the **\__BASE** parameter, you can perform [real-time subscription](subsys-dfx-hisysevent-listening.md) to the event based on the event domain **MODULEA** and event name **EVENT\_NAMEB**, or based on the event tag.

+## cl.telephony.1 Radio Module API Change
+
+
+### `isNrSupported` API Change for the Radio Module of Telephony Subsystem
+
+NR is a proper noun and must be capitalized.
+
+You need to adapt your application.
+
+
+
+**Change Impacts**
+
+The JS API needs to be adapted for applications developed based on earlier versions. Otherwise, relevant functions will be affected.
+
+
+
+**Key API/Component Changes**
+
+- Involved APIs:
+
+  isNrSupported(): boolean;
+  isNrSupported(slotId: number): boolean;
+
+- Before change:
+
+```js
+function isNrSupported(): boolean;
+function isNrSupported(slotId: number): boolean;
+```
+
+- After change:
+
+```js
+function isNRSupported(): boolean;
+function isNRSupported(slotId: number): boolean;
+```
+
+
+
+**Adaptation Guide**
+
+Use the new API. The sample code is as follows:
+
+```js
+let result = radio.isNrSupported();
+console.log("Result: "+ result);
+```
+
+
+```js
+let slotId = 0;
+let result = radio.isNRSupported(slotId);

+#### Adaptation Guide
+
+For details, see the API reference of the [@ohos.batteryInfo](../../../application-dev/reference/apis/js-apis-battery-info.md) API.
+## cl.powermgr.2 estimatedRemainingChargeTime API Change
+
+Changed the **estimatedRemainingChargeTime** API in [@ohos.batteryInfo](../../../application-dev/reference/apis/js-apis-battery-info.md) to a system API.
+
+#### Change Impact
+
+The JS API needs to be adapted for applications developed based on earlier versions. Otherwise, relevant functions will be affected.
+
+#### Adaptation Guide
+
+For details, see the API reference of the [@ohos.batteryInfo](../../../application-dev/reference/apis/js-apis-battery-info.md) API.
+
+## cl.powermgr.3 System Common Event Behavior Change
+
+The following common events are provided in the battery information through [@ohos.commonEventManager (common event module)](https://gitee.com/openharmony/docs/blob/master/en/application-dev/reference/apis/js-apis-commonEventManager.md):
+
+- COMMON_EVENT_BATTERY_LOW: common event for low battery level. It includes the remaining battery in percentage.
+- COMMON_EVENT_BATTERY_OKAY: common event for normal battery level. It includes the remaining battery in percentage.
+- COMMON_EVENT_POWER_CONNECTED: common event for connection to an external power supply. It includes the type of the power supply to which the device is connected.
+- COMMON_EVENT_POWER_DISCONNECTED: common event for disconnection from an external power supply. It includes the type of the power supply from which the device is disconnected.
+- COMMON_EVENT_CHARGING: common event for starting of battery charging. It includes the battery charging status.
+- COMMON_EVENT_DISCHARGING: common event for ending of battery charging. It includes the battery charging status.
+
+Changed the method of obtaining data from common events from **CommonEventData.data** to **CommonEventData.code**.
+
+#### Change Impact
+
+The application developed based on earlier versions needs to adapt the method for obtaining common events in the battery information. Otherwise, the original service logic will be affected.
+
+#### Adaptation Guide

+# Startup Subsystem JS API Changelog
+
+## cl.startup.1 Bundle Name Change
+
+**Change Impact**
+
+The original bundle name **@ohos.systemParameterV9** will be deleted and cannot be used anymore. Use the new bundle name **@ohos.systemParameterEnhance** instead.
+
+**Adaptation Guide**
+
+Change the bundle name from **@ohos.systemParameterV9** to **@ohos.systemParameterEnhance**. The APIs remain unchanged. The following is the sample code:
+
+```js
+import @ohos.systemParameterEnhance
+```
