You can tap on any item in the Updates tab in Software to display details about the update, what version you're updating and what the new version is etc. For the "OS Update" item, it shows that info for all the packages that are considered "OS updates"; things like the kernel, init and other libraries that can't be considered "apps" are all there with all the details you need. You can also try a manual update with "pacman -Syu" in the terminal which will list all those things too.
