Apple releases iOS 12.2 and Safari 12.1 on iOS High Sierra and Mojave. The updated version of the WebKit Intelligent Tracking Prevention (ITP) feature will further decrease trackers ability to trace user identities across websites. Apple also removed support for the now-defunct Do Not Track (DNT) signal, which was an attempt by web stakeholders to offer users an attempt to allow users an off-by-default way to ask servers not to track them. The update comes with privacy, security, and performance improvements.
