New SD to Lightning adaptor - what's changed?

I don't think anything changed I think it was just a highlight of the adapter.

 

Isn't the new one usb3 enabled for the pro where as the old one was usb2

 

he's asking whats different from the one announced yesterday vs the one released with the 12.9 IPP.

 

The Lightning to SD Card Camera Reader basically got updated back in December 2015 to be able to do USB 3 speeds.

The newer SD card reader is larger:
"larger than its predecessor when they’re placed next to each other. Measuring 5.2″ long by 1.2″ wide and 0.3″ thick (versus 4.6″ long by 1.2″ wide by 0.27″ thick), the new Reader has a longer and slightly thicker SD Card chassis, as well as a thicker cable leading to its Lightning connector, both parts no doubt in service of hidden USB 3 components inside."

"The new version is labeled as “MJYT2AM/A Lightning to SD Card Camera Reader (USB 3),” model A1595."
as per above

 

I thought the 9.7 inch Pro still only worked at USB 2 speeds? If so, is a new adapter really needed?

 

It's not.
