Apple on late Tuesday released revised versions of iOS 17.4.1 and iPadOS 17.4.1 with an updated build number of 21E237, according to MacRumors contributor Aaron Perris. The updates previously had a build number of 21E236.
The revised updates are available for all iPhone and iPad models that are compatible with iOS 17 and iPadOS 17, but they can only be installed via the Finder app on macOS and the Apple Devices or iTunes apps on Windows at this time. Apple has not made the new builds available over the air in the Settings app on the iPhone and iPad.
It is unclear what changed between the builds, if anything, but any potential differences are likely very minor. For those curious, we have confirmed that the new builds do not contain any references to unreleased iPad models.
There have been sporadic reports on social media about iOS 17.4 and iOS 17.4.1 causing some iPhones to get stuck in a boot loop, so perhaps the new build will allow those devices to be properly restored, but this is merely speculation.
iOS 17.4.1 and iPadOS 17.4.1 were first released last week with bug fixes and security patches.
