Apple publishes Release Candidate for iOS/iPadOS 18.5, macOS Sequoia 15.5, watchOS 11.5, tvOS 18.5 and visionOS 2.5. RC for iPadOS 17.7.7 is also available with bug fixes.
Apple did not update Xcode 16.4 beta though.
iOS 18.5 will allow satellite services (like T-Mobile Starlink integration) to work older iPhone models. These services work differently from Emergency SOS satellite connectivity available in newer iPhone models.
ScreenTime now has notification when user of managed device successfully entered ScreenTime passcode. That might indicate that kid was able to guess that passcode.
