-# Location Subsystem Changelog
-
-## cl.location.1 Deletion of the geoLocationManager.requestEnableLocation API in API Version 9
-
-When the location function is disabled, your application can call the **geoLocationManager.requestEnableLocation** API to request the user to enable the location function. However, this API is seldom used, and user experience for this API is not very good because the user is not notified of the scenario in which your application uses the location information.
-
-Therefore, your app shows a popup, asking the user to go to the settings page and enable the location function. In addition, the popup clearly states the scenarios in which the location information will be used, improving user experience.
-
-**Change Impact**
-
-Your application cannot use the **geoLocationManager.requestEnableLocation** API in API version 9 to request the user to enable the location function. Instead, you need to implement a popup asking the user to enable the location function for your application.
-
-**Key API/Component Changes**

-|  -- | -- | -- | -- |
-|geoLocationManager| method | function requestEnableLocation(callback: AsyncCallback<boolean>): void; | Deleted from API version 9. | 
-|geoLocationManager| method | function requestEnableLocation(): Promise<boolean>; | Deleted from API version 9. |

 # Globalization Subsystem Changelog
 
-## cl.global.1 Runtime Authentication Added for System APIs
-
-The internationalization component of the globalization subsystem adds runtime authentication for system APIs in certain scenarios. The following changes are made in API version 9 and later:
- - Setting the system language, country or region, and area
- - Setting the 24-hour format of the system
- - Adding and removing the preferred language
- - Setting localized numbers
-
-You need to adapt your application based on the following information.
-
-**Change Impact**
-
-APIs involved in the preceding scenarios can be properly called only by system applications that have the **UPDATE_CONFIGURATION** permission.
-
-**Key API/Component Changes**

- - Involved APIs:
-   - setSystemLanguage(language: string): void;
-   - setSystemRegion(region: string): void;
-   - setSystemLocale(locale: string): void;
-   - set24HourClock(option: boolean): void;
-   - addPreferredLanguage(language: string, index?: number): void;
-   - removePreferredLanguage(index: number): void;
-   - setUsingLocalDigit(flag: boolean): void;
-
-**Adaptation Guide**
-
-Make sure the application trying to call any of the above APIs is a system application. Non-system applications are not allowed to call the APIs.
-An exception will be thrown upon lack of a necessary permission or a call request from a non-system application. The exception can be captured via **try-catch**.
-
-```js
-import I18n from '@ohos.i18n'

-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.

-## 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.
