New and Un-proved!

So I'm looking in the pantry for something to eat, and I come upon these:



Now, I was too hungry to care about the disclaimer at the time, but I still found it somewhat unsettling. I don't remember ever being disappointed with the taste of those Doritos in the past... what did they have to improve on? Dorito-newcomers may see this bag and think "Well, it looks like they messed up earlier, how do I know these don't taste bad, too?" or veteran Dorito-eaters may not want an improvement made on a taste they used to like. Either way, I didn't notice a difference.
They were stale.
