## What's new

- The `mimeType` property in the `ContentData` class was added to enforce the Mime-Type for media content.


## What's changed

- Removed `FOREGROUND_SERVICE` and `FOREGROUND_SERVICE_DATA_SYNC` permissions from the SDK's `AndroidManifest.xml` file.

  - These permissions were previously declared inside the SDK AAR and automatically merged into the host app's manifest via Android Manifest Merger, causing Google Play review rejections for apps that do not use the download feature.

  - Starting from this version, apps that use the download feature must declare these permissions explicitly in their own `AndroidManifest.xml`.

  - Apps that do not use the download feature are not affected and do not need to declare these permissions.

  - See the Download Feature Setup section in the QuickStart guide for details.
