Apple yesterday released a small update focused on stability improvements and bug fixes to Smart Keyboard users on the iPad Pro (via iMore). When plugged into the 12.9-inch iPad, the device will notify users of an Accessory Update for the Smart Keyboard, which can be updated and installed thanks to the Smart Connector joining the iPad and the keyboard.
The new update is mainly focused at improving the connection stability between the Smart Keyboard and iPad Pro, along with addressing an unexpected wake-up issue some users have faced recently. The update is relatively quick, but users can opt to install it at a later time similar to larger iOS updates.
Recent numbers on the iPad Pro's sales point to an overall "successful" launch for the plus-sized tablet. During the iPad Pro's launch quarter Apple's device reportedly outsold the Microsoft Surface, despite an overall decline in iPad sales most likely due to the absence of an iPad Air refresh last year.
