Release notes

What changed

Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.

The visible changes paired a security repair with regional mapping maintenance: emergency-call lock-state handling could no longer provide the documented route into Phone, and Maps received improvements specific to Japan.[1][2]

Apple’s advisory also blocked overlapping-segment executables, hid kernel structure addresses, protected backup restore permissions from symbolic-link paths, validated USB pipe pointers, and strengthened WebKit SVG type handling.[3]
