iOS 11.3 Release Notes Reportedly Leak Ahead of Launch

iOS 11

Earlier this week, Apple launched a brand new 9.7-inch iPad, and, a day later, released iOS 11.3 for the new device ahead of the public launch for both the software and the hardware.

Now, on what is expected to be the wide release of iOS 11.3, developer Pierre Blazquez has published several images on the social network Twitter, all of which reportedly include the release notes for iOS 11.3. These were allegedly obtained directly from Apple’s servers, but, as always, without an official announcement on Apple’s part, take all of this with a grain of salt or two.

That being said, if these are indeed accurate release notes for the upcoming software update, there are a couple of interesting aspects. First, to get it out of the way, all of the things we expected to find in iOS 11.3 –thanks to the beta seeds ahead of the public launch– are right there, including the new Animoji for iPhone X owners, the new battery health feature (which will remain in a beta version even with the public release of iOS 11.3), and the addition of ARKit 1.5, which will include new features for the augmented reality platform.

There are some noteworthy omissions, though. As noted today by MacRumors, the release notes do not include any mention of Messages on iCloud, the feature that Apple announced back in September of last year, which will allow better syncing of iMessages across devices by way of iCloud. That feature was actually switched on in the later betas of iOS 11.3 and macOS High Sierra 10.13.4, so it’s curious that it’s being left out of the final release.

Unsurprisingly, though, is the fact that AirPlay 2 is not listed in these release notes. Apple launched the feature in January of this year, with one of the early beta seeds of iOS 11.3, but in February removed the feature altogether. There is no word on when this new feature will be officially rolled out, but if these release notes are any indicator, it won’t be with the public launch of iOS 11.3.

Here is the list of new features noted in the release notes for the upcoming iOS 11.3:

    Augmented Reality

    • ARKit 1.5 allows developers to place virtual objects on vertical surfaces, such as walls and doors, as well as on horizontal surfaces.

Our Take

There is no way of knowing if these release notes are the real deal just yet, but, we should find out soon as Apple will more than likely launch iOS 11.3 to the public later today. Tomorrow, Friday, March 30, is a holiday in the United States, so it wouldn’t make much sense to launch the software update on that date.

Are you looking forward to iOS 11.3?
