Apple (APPL) made the upcoming update available to developers and public beta testers shortly after it was announced, and users are starting to find unannounced features.

As 9to5Mac reported, a developer noticed the new feature after connecting Logitech’s Create keyboard to his iPad Pro running the second beta of iOS 9.3.

Logitech’s keyboard uses Apple’s Smart Connector to interact with the iPad Pro. The small connector provides a continuous connection and power to the keyboard, eliminating the need for Logitech to include a battery and Bluetooth functionality in the keyboard.
