Downloading it now. Will update you soon with changes.
EDIT: Ok, I finished installing. I don't see any changes at all in the menus or settings. Most likely, this seems to be only a security update. I'm not sure if anything is done about the upscaling issue or how to check that. Maybe someone would like to try to see if upscaling works? But for now I don't see any changes.
