Apple released the iOS 11.4 update for iPhone and iPad devices earlier this week. The update brought performance improvements, Messages in iCloud and other useful features. However, the security details of the latest iOS update weren’t posted until today.

The iOS 11.4 security details are now available on the Apple website for anyone willing to learn about the security improvements iOS 11.4 brings to their iPhone or iPad.

Other than iOS 11.4, security details for macOS High Seirra 10.13.5, tvOS 11.4 and watchOS 4.3.1 are also now available.
