We expected a lot of announcements from Apple’s event today, including the new 4-inch iPhone SE and a smaller 9.7-inch iPad Pro, both of which came to fruition. Also on that list of things we expected to see was the release of software version iOS 9.3, which has been in beta for quite some time now. As anticipated, iOS users can in fact expect to see iOS 9.3 roll out to their iOS devices at some point today.

Notable features that come with iOS 9.3 are the addition of Night Shift, which “warms” the tone of your display. Studies have shown that the warmer tones help regulate our circadian rhythm by mimicking sunset; the typical “blue” light that our phones typically give off can throw that off.

iOS 9.3 also brings the ability to lock notes written in the Notes app with passcode or Touch ID, which will be a highly useful feature for people who would like to store sensitive account or security information directly on their device. The update also touts a more personalized News app with updates to its “For You” section. Additional improvements have also been made to the Health app, as well as updates for the iPad to improve classroom functionality, and some new features for CarPlay.

Users who have access to 3D Touch will have new shortcuts for Settings, Compass, Health, Store, Weather, and Stocks.
