Yep good question and I'm not exactly sure of the answer either.
One thing I can certainly tell you is that updates are downloaded automatically but I don't think you're notified when your device is updating or has updated.
I'm sure I've seen an Update Firmware link on the Amazon Echo home page somewhere too.

One thing that isn't clear to me is whether you can force an echo device to look for an update, and if so, how. I have the original amazon echo, and I've never bothered to look into this question; I just figured updates would come when they came, but how to know if you have actually received one? Mary
