As far as I know all those menus (shader, add menu etc) have been changed that you can now just open them and start typing what you want without hitting search first. Not sure if you can change it back, but I find it much faster now to just press shift+a and type first couple of letters of lets say color ramp and it pops right up and I can click it without going through the menus first. Once you’re used to it you might find it very convenient. Same goes for the modifiers for example.
