**Key API/Component Changes**
- Involved APIs:
enum HitTestTypeV9
- Before change:
```ts
enum HitTestTypeV9
```
- After change:
```ts
enum WebHitTestType
```
**Adaptation Guide**
Replace **HitTestTypeV9** with **WebHitTestType**.
## cl.web.2 HeaderV9 Name Change

The struct **HeaderV9** and APIs that use **HeaderV9** as a parameter or return value cannot be used in OpenHarmony 3.2.10.7 and later versions.
**Key API/Component Changes**
- Involved APIs:
interface HeaderV9
- Before change:
```ts
interface HeaderV9
```

## cl.web.3 Member Change of HitTestValue
Rename the member variable **HitTestTypeV9** in the **HitTestValue** struct **WebHitTestType** to meet the naming conventions.
**Change Impact**
The struct **HitTestValue** and APIs that use **HitTestValue** as a parameter or return value cannot be used in OpenHarmony 3.2.10.7 and later versions.
**Key API/Component Changes**
- Involved APIs:
interface HitTestValue
- Before change:
```ts
interface HitTestValue {
/**
* Get the hit test type.
*
* @since 9
*/
type: HitTestTypeV9;
/**
* Get the hit test extra data.
*
* @since 9
*/
extra: string;
}
```
- After change:
```ts
interface HitTestValue {
/**
* Get the hit test type.
*
* @since 9
*/
type: WebHitTestType;
/**
* Get the hit test extra data.
*
* @since 9
*/
extra: string;
}
```
**Adaptation Guide**
Replace **HitTestTypeV9** with **WebHitTestType**.
## cl.web.4 Parameter Type Change of loadUrl
Changed the type of the **headers** parameter in **loadUrl** to **WebHeader** to meet the naming conventions.

**Key API/Component Changes**
- Involved APIs:
loadUrl(url: string | Resource, headers?: Array\<HeaderV9>): void
- Before change:
```ts

onMessageEvent(callback: (result: WebMessage) => void): void;
```
**Adaptation Guide**
Instead of importing APIs from the original **WebMessagePort** class, import APIs from **@ohos.web.webview** as follows:
```ts
import web_webview from '@ohos.web.webview';
```
## cl.web.7 Moving of the HitTestValue Class
Moved the **HitTestValue** class to **@ohos.web.webview.d.ts**; changed **HitTestValue** from a class to an API; changed the **getType** and **getExtra** from APIs to attributes.

```ts
getType(): HitTestType;
getExtra(): string;
```
- After change:
```ts
type: WebHitTestType;
extra: string;

Instead of importing APIs from the original **HitTestValue** class, import APIs from **@ohos.web.webview** as follows:
```ts
import web_webview from '@ohos.web.webview';
```
## cl.web.8 Moving of API Version 9 APIs Under WebCookie
Moved APIs of API version 9 in the **WebCookie** class to **web.webview.webview.WebCookieManager**
and added error throwing.
**Change Impact**
If your application is developed based on earlier versions, note that the **d.ts** file storage location and the name of the module to be imported are changed. In addition, be mindful of the error codes now that the APIs in the class support error code processing.
The APIs in the class are static.
