Apple is still testing the iOS 9.2.1 update, but as early as now, the company is already developing the iOS 9.3 beta, which is said to be one of the largest updates to the tech giant's latest operating system.

As provided by Mac Rumors, listed below are the changes and features users should expect in iOS 9.3.

Night Shift

The new feature called Night Shift is designed to automatically reduce the amount of blue light an iOS user is exposed to at night. This will be done by shifting the screen displays of the iPhone and iPads to more yellow tones. Research studies found out that being exposed to blue light at night can interrupt the circadian rhythm, leading to difficulty in sleeping.

You can view the Night Shift settings in the Display and Brightness section of the Settings page. This section now shows a new option labeled Blue Light Reduction, which can be set to Cooler or Warmer. A Schedule option also allows users to set a custom schedule or pick when to turn on Night Shift from sunset to sunrise.

CarPlay

The Apple Music CarPlay app is now equipped with New and For You sections for improved music discovery, and a Nearby feature in Maps present better access to information about which establishment is near. It can also provide suggestions for locations you might want to go to.

Apple has provided a complete list of all the cars in the United States and other countries that offer CarPlay support. This includes over 100 2016 and 2017 models from 22 auto companies including Audi, Buick, Cadillac, Chevrolet, Citroën, DS Automobiles, Ferrari, Ford, GMC, Honda, Hyundai, Mercedes-Benz, Mitsubishi, Opel, Porsche, Peugeot, Seat, Škoda, Suzuki, Volkswagen, and Volvo.

Quick Actions

IPhone 6S and 6S Plus users now have new 3D Touch Quick Actions for some of the stock apps, including Weather, Settings, Compass, and Health. Quick Action options are also available for the App Store and iTunes store apps.

Notes & News

Touch ID or a password can now be used within the Notes app. When this is enabled, Notes will require a password or a fingerprint when opening password-protected Notes, which can also be set on a note-by-note basis within the app.

The For You section in the News app, meanwhile, is now integrating trending topics and specific picks from Apple editors to assist users in discovering content. Other new features include a new landscape view for News on the iPhone, in-line video playback in news stories, and quicker content updating when accessing the News app.

Be sure to check out updates in other apps such as Health, Education, Apple Watch, Live Photos, Wallet/Apple Pay, Siri, and App Switcher as well.
