Yes, some of the hotkeys have changed in Blender 3. You can find a hot sheet here https://www.dropbox.com/s/jg4fs4i8zw5bxt7/Blender%203.0%20Shortcuts%20v1.2.pdf?dl=0 but they also have better menus now so you don't need so many hotkeys and there's a search function that will help you find things too
