Apple is testing iOS 26.5.1 internally, and 9to5Mac visitor logs confirm the minor update is on the way. iOS 26.5 landed just last week, but the company appears to have one more release before WWDC's iOS 27 reveal. Based on historical patterns, this update could ship as early as the week of Memorial Day, since Monday itself is a holiday.

Minor point updates typically deliver bug fixes and security patches, though they sometimes add hardware compatibility. iOS 26.3.1 brought Studio Display support, while iOS 26.2.1 added AirTag 2 support. If Apple has a surprise hardware announcement at WWDC, iOS 26.5.1 could include support for it, but the more likely outcome is routine fixes and security improvements.

Users running iOS 26.5 can share their experience in the comments. The timing positions Apple to clear the decks before the bigger WWDC announcements roll out.
