Apple typically releases minor updates occasionally to add new features or fix software glitches. This is one of Apple’s larger in-between updates; iOS 9.3 brings a handful of all-new features.
Night Shift, for instance, automatically adjusts an iPhone’s display to remove blue light during use in the evening. Studies have shown blue light can interfere with individuals’ ability to sleep. Night Shift is intended to reduce this effects.
Apple is also making it easier to keep users’ notes private. iOS 9.3 adds the ability to password protect entries.
Those who use Apple News, the company’s news-reading software, will notice a subtle change—the app is getting a “Top Stories” section to make it easier to organize new and important content.
