Each version of this integration matches a specific build of Unreal Engine. Here is what has changed in the 2022.1.16 release of the integration (in addition to upgrading to the new Unreal build).

Note: This integration does not support experimental Unreal Engine features.

Note: This integration was compiled against Unreal Engine version 4.27, 5.2, 5.3, and 5.4. It was tested against Unreal Engine 5.4. Deprecation Notice: Support for Unreal Engine 4.27 will be removed in a future minor release. We recommend that you use Unreal Engine 5.2 or later.

For earlier versions, please refer to Previous Release Notes.
