Apple on Thursday released the first beta version of macOS Monterey 12.2 for developers, which comes with a new music app and other enhancements. Although the company hadn’t released any new beta versions for its other operating systems at the time, a beta version of iOS 15.3 was leaked via Apple’s developer website.
The leak of Apple’s software before the official announcement is quite unusual, however, it has happened a few times before, such as when the company mistakenly released an internal HomePod firmware that led to the iPhone X leaks in 2017.
This time, for some unknown reason, the beta version of iOS 15.3 was hidden on the Apple Developer website, where developers can download IPSW files to manually restore and update Apple devices.
Besides iOS 15.3, Apple is also working on watchOS 8.4 and tvOS 15.3. Hidden code on Apple’s website suggests that all beta versions were expected to ship alongside macOS 12.2 beta on December 16, but it is unclear why the company was putting off the other beta versions.
These are the build numbers for all the new betas:
- 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 various versions of iOS 15.3 beta 1. However, there doesn’t seem to be a lot of new stuff in these versions. More specifically, there are some internal changes related to Siri APIs and some tweaks to Apple apps like News, but generally speaking, iOS 15.3 beta 1 only comes with general bug fixes and improvements.
We were unable to review the beta versions of watchOS 8.4 and tvOS 15.3 as they can only be downloaded via OTA.
When will these beta versions be released to the public?
Beta versions are now officially available to developers. As for the public release, the download URL for the hidden builds contains “Winter2022”, suggesting that Apple expects to release them sometime between January and March next year.
This also corroborates that the long-awaited Universal Control feature will take even longer to launch, as Apple recently delayed it until spring 2022. The feature will likely be enabled with iOS 15.4 and macOS Monterey 12.3.
