+# 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.

+# 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**
+

+| @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.

+| @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);
+```
