Release notes

Overview

Editorial synthesis with inline references and a source ledger when citations are available.

iOS 26.3 was a maintenance and security release. Apple’s consumer note does not itemize feature or bug-fix changes, so the version record does not invent a user-facing feature list.[1]

The security advisory supplies the concrete technical record across locked-device privacy, sensitive-data access, media processing, kernel and network protections, sandboxing, system services, and WebKit. One dyld entry is carefully limited to Apple’s statement about attacks against versions before iOS 26.[2]
