Apple Seeds First Beta of iOS 9.3 to Developers

What's new in iOS 9.3:

Apple Watch - With iOS 9.3 and watchOS 2.2, the iPhone is able to pair with more than one Apple Watch. Both updates are required, with each watch running watchOS 2.2 and the iPhone running iOS 9.3. WatchOS 2.2 was seeded to developers alongside iOS 9.3.

Night Shift - iOS 9.3 includes a feature that reduces blue light at night, much like f.lux does on a Mac.

Notes - Notes is now password protected and there are new features for sorting by date created, date modified, or alphabetically.

Apple News - News algorithms have been improved to offer more tailored articles in the For You section. There's also a new landscape mode and in-line video playback.

Health - Health has been updated with a new interface that makes it easier to see move, exercise, and stand data. There's also a new menu in certain categories to help users discover apps that can be used to track health data.

CarPlay - CarPlay includes iOS 9 features like New and For You sections in Apple Music along with a Nearby feature in Maps for discovering the best local restaurants, coffee shops, and more.
Education - iOS 9.3 includes multiple Education-oriented features including shared iPads for students, a new Classroom app, and an Apple School Manager.

Apple Seeds First Beta of tvOS 9.2 to Developers

What's new in tvOS 9.2:

Bluetooth keyboard support - tvOS 9.2 now supports Bluetooth keyboards, allowing a keyboard to be paired to the Apple TV for text entry. This is a major feature that was missing from previous versions of tvOS and its addition should make it much easier to do things like enter passwords.

Folders - tvOS 9.2 includes support for grouping apps in the Home screen into Folders, much like one can do on an iOS device. Folders are a bit buggy on the Home screen, but this will improve in subsequent betas.

MapKit - tvOS 9.2 supports MapKit, allowing developers to implement maps into their tvOS apps.

Siri - Siri now includes support for US Spanish (in the US only) and French Canadian (in Canada only). UK English, Australian English, and US English are now available in the UK, Australian, and US Storefronts when English is set as the tvOS language.

App Switcher - There's a new look for the App Switcher interface in tvOS.

Podcasts - The Podcasts app is now available on the fourth-generation Apple TV.
