Apple has released Safari Technology Preview 248, an experimental browser designed for testing future Safari features. This update addresses numerous bug fixes and performance improvements across various components including Accessibility, CSS, JavaScript, Media, Networking, Rendering, Security, and Web APIs.

The release is compatible with macOS Tahoe and macOS Golden Gate. Users can download the update via Software Update in System Preferences or System Settings, or directly from Apple's website. Safari Technology Preview runs alongside the standard Safari browser and aims to gather user and developer feedback.

Safari Technology Preview was first introduced in March 2016 to provide a platform for testing upcoming browser functionalities. It is available to all users without requiring a developer account, facilitating broader testing and feedback collection for Apple's browser development process.
