Build 23G5043d arrived three weeks after the first round of 26.6 betas. The release centers on bug fixes and minor refinements — the most visible addition is new language notifying users when they hit the maximum number of blocked contacts. Some reports also flag an unreleased anti-snatching mechanism that locks the device if the phone is grabbed from a user's hand, though Apple has not confirmed it publicly. With iOS 27 on track for September, the 26.x branch is in maintenance mode. Beta 2 is the cadence release you'd expect: nothing that changes your app compatibility story, but worth pulling if you're testing edge cases around contact-blocking or device-lock behavior.
