They didn't exactly do away with it, just changed the way they inform you.
You can either go ahead and run it from the notification or delay it for a while.
OR
you can run Software Update from the Apple menu where it will show you all the details about the software update.

I'm running 10.10.2 and something that bothers me is Software Update (or lack thereof). I am not happy with getting messages that there is an update to be downloaded and not having any idea what it is. Is there some way to fix this? And... why would Apple do away with it? Dumb, dumb, dumb to my thinking anyway.
Thanks, Old Granny Lola
