However if there is a big technology change then that can cause a problem, and of course that's something that is not always obvious to a user as very often it's the same functionality with no additional benefit just with a different technology underneath.
Also imagine what needs to be tested. With Apple releasing an OS every year that's 4 OSX versions we support for Macintosh with PitStop, plus of course Windows, plus multiple Acrobat versions. That's a lot of permutations.
I could not agree more. If people don't see a visual change in an update they assume not much has been changed. I fight that with our internal staff..
