No, any specific change you are talking about? I know recently they updated the look, like with Sams but im not on there too much so hopefully someone else knows.
All it says when I log onto my account online is "Make sure your account contact information is up to date. We will soon be bringing you a new enhanced online portal with better security." That may not be word for word, but pretty close. It doesn't say specifically but it does generally say a safer experience online.
