Apple on Wednesday released iOS 26.4.2 to fix a bug that allowed messages deleted by a user to remain on the iPhone.
“Notifications marked for deletion could be unexpectedly retained on the device,” Apple said in its security notes about the update. “A logging issue was addressed with improved data redaction.”
Beyond that, it seems like a minor update that focuses on various bug fixes and incremental performance improvements rather than new features. Tablet users got iPadOS 26.4.2 at the same time.
Plus, those not yet willing to make the jump to iOS 26 got their own update — iOS 18.7.8 also appeared on Wednesday, along with iPadOS 18.7.8.
