Confused about versions

I have been a long time user of Norton Internet Security and my subscription just renewed on 7/12/15 and I received an updated version (i.e. 22.5.2.15) on both of my PC.  Today I was looking at the Norton Web site and it says that Norton Internet Security has been discontinued and that Norton Security is the new name for multiple versions of the product.  Did I get an old version of the product with my subscription renewal?  Am I entitled to a different version and if so, which version?  How would I get the latest version of Norton Security that I'm entitled to as when I logon to my account is still says that my product is Norton Internet Security and that my product is up to date?  Not that I'm particularly concerned as it is a newer version of the product but I'm kind of surprised that this change has occurred I the last 18 days and there was no notice that this change was taking place.  Any help will be appreciated.
