This post is made for the people who want to know what IOS 9.3 has brought. Here is a list of things that are new and also is it worth updating.
Night Shift
Night Shift uses your iOS device’s clock and geolocation to determine when it’s sunset in your location, then it automatically shifts the colors in your display to the warmer end of the spectrum.1 In the morning, it returns the display to its regular settings. Pleasant dreams.
Keep your notes private with fingerprint or passcode
Now you can secure the notes that contain your most personal data — such as financial details, medical info, or website logins — with a password or fingerprint. You can also sort notes by date created, date modified, or alphabetically.
News app personalize
The articles in For You are now better tailored to your particular interests. And to help you discover new Favorites, For You suggests trending topics and Editors’ Picks. When a story contains video, you can play it right from your feed. On your iPhone, you can view everything in landscape. And when you check for updates, the latest stories appear much faster — so you can catch up on the day’s events quickly and easily, Also IOS 9.3 has added the possibility to draw, and now you can make lists or checklists in notes.
CarPlay has bin added
With iOS 9.3, CarPlay adds even more useful features. New and For You from Apple Music — with songs, artists, and albums handpicked by experts, plus selections based on your preferences — are right at hand on your screen. And the Nearby feature in Maps lets you find gas, parking, restaurants, coffee, and more with a tap. So you’ll know the best places to stop, whether you’re on your daily commute or an epic road trip.
Apple School
iPad opens up new, more engaging ways of teaching and learning. iOS 9.3 includes a preview of new features that will make it even easier for schools to put devices where they’ll have the greatest impact — in the hands of students.
Should you update?
Well it depends because if you want to jailbreak I say stay on your current version of IOS and wait if Pangu(Trusted) or TaiG(Trusted) releases a jailbreak for IOS 9.3, If you don't care to jailbreak then I really recommend updating because it has new features that are pretty useful for example Night Shift, CarPlay and issue fixes. Also for the jailbroken people if you are running any jailbreakes the Night Shift doesn't really matter because Flux does the same thing as Night Shift.
