Agora Video SDK 3.0.1 for Unity was released on September 18th, 2020. The Unity SDK is based on the native SDK 3.0.1 and includes new features such as Geo-Fencing and iOS 14 Local Network Permission support. It also addresses various issues from previous releases, including screen sharing for UWP windows, RGBA pixel format compatibility, transcoding fixes, and build settings improvements. Developers are advised to delete the entire AgoraEngine folder before importing version 3.0.1 due to changes in enum types and names.
