iOS 26.4 beta dropped with AI-powered Apple Music but not overhauled Siri.

Apple's iOS 26.4 beta update introduces several new features, including Playlist Playground in Apple Music, which uses AI to create playlists based on user input. The update also includes video podcast support, a 'Concerts Near You' feature, and Stolen Device Protection enabled by default. These enhancements aim to improve user experience and security.
