The firmware on the old and new units reports the same revision levels and dates.  I am fairly certain that whatever is going on is in the DS1620 chip.  Also,  if they were going to remove the high res temp code they probably would not have left in the "subtract 0.25C" step and the software filter.

I have contacted Maxim to see if they know of any changes in the DS1620 chip between 2003 and 2005.
