Jeff Hooten amongst others have seen a digital version and a traditional version of the film. We've been reporting there have been changes between the two editions, and this appears to be the first one:

Hey, I was lucky enough to see an advanced screening of ATOC at 7:30 PM, which was in the digital format, then I went to a midnight showing, which was not, and there were some minor differences in the movie. The one difference I remember was at the very end. In the digitally projected movie there is a quick close up of Padme holding Anakin's robotic hand, which was missing the second time I watched the movie. Perhaps others have noticed similar differences.
