Cool! It's about time.
Wait! I thought they automatically were adding updates option. Looks like that's not the case.
My guess is that the option won't be there unless there is an update available. So if there is one, you'll get an email directing you to download it if you want it.
I think they will continue to send notices of updates because it's not the sort of thing most people would check regularly for all their books. But it's nice that now if you get it, you won't necessarily use any notes you've made. Not that I ever really made any

but still.
