The second beta of iOS 9.3, which was seeded to developers on Monday and the public earlier today, includes a new feature that allows the iPad Pro's Smart Connector to update accessory firmware



From MacRumors:

The new feature was first spotted by German developer Stefan Wolfrum (via Cult of Mac) when he plugged his Logitech Create keyboard case into his iPad Pro.

In the past month, several users in the MacRumors forums have noted that the Create keyboard case suffers from lag and dropped keystrokes. Forum member iwill424, who also reported that his Create keyboard had its firmware updated when plugged into an iPad Pro running iOS 9.3 beta 2, said that both issues were resolved by the firmware update.
