Apple’s software updates are once again raising eyebrows, as a recent iOS and iPadOS revision has quietly been released with a version number and update method that hint at a minor release.
There was already confusion surrounding Apple’s announcement of iPadOS 17.4.1 for March 26, 2024, despite it being available alongside iOS 17.4.1 since March 21. Initially, it seemed like a simple miscommunication within Apple, but now there’s more to the story. Apple has rolled out a new update for both iOS and iPadOS, labeled with a build number of 21E237, whereas the previous release on March 21 carried the build number 21E236.
Speculations arise suggesting that this release might be tailored to specific devices, possibly including the latest iPads. Interestingly, despite the availability of build 21E237, none of the AppleInsider staff received the usual notification, and all tested iPhones indicate that 21E236 is the latest version. Notably, this new update cannot be downloaded over the air; users must connect their iPhones or iPads to their Macs to obtain it. This indicates that Apple isn’t particularly concerned with ensuring every user receives this update. Furthermore, the minute difference in build numbers suggests subtle changes that might require scrutiny to notice.
Considering that there were approximately 17 versions of the March 21 update tested at Apple Park before its release, the existence of just one version now implies minimal alterations from the previous iteration. It suggests that Apple may have thoroughly tested the changes and found no need for further adjustments, possibly even for the upcoming iPad Pro and iPad Air releases.
Apple typically remains tight-lipped about its updates, often only commenting on security aspects. It’s unlikely that they will divulge details about this particular situation. Given the negligible difference in build numbers, it’s plausible that the change might have been as trivial as correcting a typo.
