iOS 26.4 has been released, a major update for the mobile platform. The new features include a new AI capability called 'Playlist Playground', which allows users to create playlists with a simple text prompt. The Podcasts app has also been updated with a new video experience and seamless switching between watching and listening to shows. The fullscreen design for albums and playlists has been lauded as a beautiful addition to the Music app's full UI. The most recent feature is the addition of new emoji to the iPhone, which Apple typically adds new features every year.
