# File Subsystem Changelog
## cl.file.1 mediaLibrary APIs Changed
The **MediaLibrary** class of the multimedia component is replaced by the **FilePicker** class.
**Change Impact**
For applications developed based on earlier versions, pay attention to the changes of APIs. **FilePicker** is a system application preset in OpenHarmony. You can use it to select and save files.
**Key API/Component Changes**
The APIs of **MediaLibrary**, located in **@ohos.multimedia.medialibrary**, are deprecated. The **FilePicker** class, located in [@ohos.file.picker](https://gitee.com/openharmony/interface_sdk-js/blob/master/api/@ohos.file.picker.d.ts) is used.

**Adaptation Guide**
For example, refer to the code snippet below to call an API to select an image:
```js
import picker from '@ohos.file.picker';
async function example() {
try {
let PhotoSelectOptions = new picker.PhotoSelectOptions();
PhotoSelectOptions.MIMEType = picker.PhotoViewMIMETypes.IMAGE_TYPE;
PhotoSelectOptions.maxSelectNumber = 1;
let photoPicker = new picker.PhotoViewPicker();
photoPicker.select(PhotoSelectOptions).then((PhotoSelectResult) => {
if (PhotoSelectResult !== undefined) {
console.info("PhotoViewPicker.select pass, PhotoSelectResult uri: " + JSON.stringify(PhotoSelectResult));
} else {
console.error("PhotoViewPicker.select PhotoSelectResult is undefined");
}
}).catch((err) => {
console.error("PhotoViewPicker.select fail, err: " + err);
});
} catch (err) {
console.error("PhotoViewPicker fail, err: " + err);
}
}
```
# Util Subsystem Changelog
Compared with OpenHarmony 3.2 Beta4, OpenHarmony 3.2.10.7(MR) has the following API changes in the util subsystem.
## cl.util.1. randomUUID Name Changed
The **randomUUID** function name is changed to **generateRandomUUID**.
Before change: function randomUUID(entropyCache?: boolean): string <br>After change: function generateRandomUUID(entropyCache?: boolean): string
You need to adapt your application.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
**Key API/Component Changes**
| Module | Method/Attribute/Enum/Constant | Change Type|
| :---------- | ------------------- | ------- |
| @ohos.util | function randomUUID(entropyCache?: boolean): string | Deleted |
| @ohos.util | function generateRandomUUID(entropyCache?: boolean): string| Added |
**Adaptation Guide**
Refer to the code snippet below to call **generateRandomUUID** in your application.
Example:
```ts
import util from '@ohos.util'
let uuid = util.generateRandomUUID(true);
console.log("RFC 4122 Version 4 UUID:" + uuid);
// Output:
// RFC 4122 Version 4 UUID:88368f2a-d5db-47d8-a05f-534fab0a0045
```
## cl.util.2 randomBinaryUUID Name Changed
The **randomBinaryUUID** function name is changed to **generateRandomBinaryUUID**.
Before change: function randomBinaryUUID(entropyCache?: boolean): Uint8Array<br>After change: function generateRandomBinaryUUID(entropyCache?: boolean): Uint8Array
You need to adapt your application.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
**Key API/Component Changes**
| Module | Method/Attribute/Enum/Constant | Change Type|
| :---------- | ------------------- | ------- |
| @ohos.util | function randomBinaryUUID(entropyCache?: boolean): Uint8Array; | Deleted |
| @ohos.util | function generateRandomBinaryUUID(entropyCache?: boolean): Uint8Array| Added |
**Adaptation Guide**
Refer to the code snippet below to call **generateRandomBinaryUUID** in your application.
Example:
```ts
import util from '@ohos.util'
let uuid = util.generateRandomBinaryUUID(true);
console.log(JSON.stringify(uuid));
// Output:
// 138,188,43,243,62,254,70,119,130,20,235,222,199,164,140,150
```
## cl.util.3. contains Parameter Type in the LRUCache Class Changed
The **contains** parameter type in the LRUCache class is changed from **object** to **K**.
Before change: contains(key: object): boolean <br>After change: contains(key: K): boolean
You need to adapt your application.
**Change Impact**
JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.
**Key API/Component Changes**
| Module | Class | Method/Attribute/Enum/Constant | Change Type|
| :-------- | ---------| -------------------------------- | -------- |
| @ohos.util | LRUCache | contains(key: object): boolean | Deleted |
| @ohos.util | LRUCache | contains(key: K): boolean | Added |
**Adaptation Guide**
Follow the code snippet to use the **contains** function in your application.
Example:
```ts
import util from '@ohos.util'
let pro = new util.LRUCache();
pro.put(2,10);
let obj = {1:"key"};
let result = pro.contains(obj);
