You can download it on the Epic Games Launcher and GitHub. In this release, PCG, Motion Design, Substrate materials, and first-person rendering are all moving to Production Ready status. MegaLights is moving up to Beta status and gaining support for directional lights, niagara particle lights, translucency, and hair strands. Additionally, this release introduces a new in-editor AI assistant. Apparently it is trained on the Unreal Engine documentation and source code. Time will tell how reliable it is.
