A natural fact about humans is that they have long memories but not a good way to tell how long ago events happen if they do not deal with them all the time. So when talking about this release with various old-time users.. the response is always "AGAIN?" even if it was 4+ years since the last change. The memories that immediately came up were ones of all the previous changes and the brain processes it as something that just happened.
In other words, get used to the fact that every time you change something you will get this response.. in fact it will more likely be more vitriolic the longer the time since the last change and how critical it is to some once in a while task.
