Apple today released Safari Technology Preview 256, an update to the experimental browser first introduced in March 2016. The release lets users test features planned for future Safari versions.
Version 256 includes fixes and updates for Accessibility, Animations, CSS, Editing, Forms, HTML, JavaScript, Media, Networking, Rendering, SVG, Security, Web API, Web Extensions, Web Inspector, WebGL, and WebRTC.
The update is compatible with machines running macOS Tahoe and macOS Golden Gate, the newest versions of macOS. It is available through Software Update in System Preferences or System Settings for anyone who has downloaded the browser from Apple's website.
Apple designed Safari Technology Preview to gather feedback from developers and users on its browser development process. It can run side-by-side with the existing Safari browser and does not require a developer account to download and use.
