Each version of this integration matches a specific build of Unreal Engine. Here is what has changed in the 2022.1.9.8365.2862 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, 5.1, 5.2, and 5.3. It was tested against Unreal Engine 5.3. Any major Unreal Engine version more recent than the aforementioned is not currently supported, but will be in a subsequent patch release.
