Menu Starter Kit

well I was wanting to be able to go to your menu during game in case to make changes in the settings on the fly. I worked it out though where I use my pause menu , and from there I can go to your main menu.so can I migrate my projects from 4.18 to 4.19? do I need to get a 4.19 update for your kit , or does just using the 4.19 engine take care of it. other 2 issues I have are no resolutions showing up in menu and audio sliders not working(and the packaging errors mentioned above), then I would be good for now.
