# Application Access Control Subsystem Changelog

## cl.accessToken.1 Change of the Media and Files Permission Group
The original **Media and File** permission group contains the following permissions:
- ohos.permission.MEDIA_LOCATION
- ohos.permission.READ_MEDIA
- ohos.permission.WRITE_MEDIA

Changed the permission group as follows:
- Moved **ohos.permission.MEDIA_LOCATION** to the **Images and Videos** permission group.
- Moved **ohos.permission.READ_MEDIA** and **ohos.permission.WRITE_MEDIA** to the **Documents** permission group.

**Change Impact**

The permission group rather than the permission is presented in the dialog box for requesting permissions.

- Before the change, if the three permissions are applied for an application, a dialog box for requesting the media and file permissions will be displayed only once.
- After the change, if the three permissions are applied for an application, a dialog box for requesting the **Images and Videos** permissions and a dialog box for requesting the **Documents** permission will be displayed.
