iOS 15.3 mysteriously leaked via Apple Developer website
Apple on Thursday released the first beta of macOS Monterey 12.2 for developers, which includes a new Music app and other improvements. Although the company did not release any new beta versions for its other operating systems at the time, a beta version of iOS 15.3 was leaked through the Apple Developer website.
The Apple software leak before the official announcement is quite unusual, but it has happened a few times before, such as when the company mistakenly released HomePod internal firmware that led to the iPhone X being leaked in 2017.
This time, for some unknown reason, the iOS 15.3 beta was hidden on the Apple Developer Website, where developers can download IPSW files to manually restore and update Apple devices.
In addition to iOS 15.3, Apple is also working on watchOS 8.4 and tvOS 15.3. Code hidden on Apple’s website suggests that all beta versions were due to be released with the macOS 12.2 beta on December 16, but it’s unclear why the company delayed other beta versions.
Here are the build numbers for all new beta releases:
- iOS 15.3 beta 1: 19D5026g
- watchOS 8.4 beta 1: 19S5525f
- tvOS 15.3 beta 1: 19K5527e
- macOS Monterey 12.2 beta 1: 21D5025f
What’s new in these betas?
9to5Mac was able to download, analyze and even install multiple versions of iOS 15.3 Beta 1. However, there does not seem to be much new in these versions. Specifically, there are some internal changes related to Siri APIs and some tweaks to Apple apps like News, but overall iOS 15.3 beta 1 only ships with bug fixes and general improvements.
We were unable to analyze beta versions of watchOS 8.4 and tvOS 15.3 as they can only be downloaded via OTA.
When will these betas be released?
Betas are now officially available for developers. As for the public version, the download URL for the hidden versions contains “Winter2022”, which suggests that Apple plans to release them between January and March of next year.
It also corroborates the fact that the long-awaited Universal Control feature will take even longer to release, as Apple recently delayed it until spring 2022. The feature will likely be enabled with iOS 15.4 and macOS Monterey 12.3.
