No too much changed at first glance! Nice little winglet near the exhaust, presumably to tidy up the airflow to the rear wing, and maybe manipulate the exhaust gases upwards to blow it?
I thought the rear wing endplates had changed, but it looks like they've just painted the lower section black. Not sure why, need to see a clearer shot, but it could just be a paint with different friction. The Hilton sponsor that was there is evidently gone.
