I contacted Samsung tech support today because I had this exact same question. They told me that the shipped firmware is in fact newer than what's posted online. So DO NOT attempt to 'upgrade' since it would in fact be a downgrade. I asked for a changelog but they coulnd't provide any specifics at this time.
