Apple today released a new update for Safari Technology Preview, the experimental browser that was first introduced in March 2016. Apple designed Safari Technology Preview to allow users to test features that are planned for future release versions of the Safari browser.
Safari Technology Preview 253 includes fixes and updates for Accessibility, Animations, CSS, Canvas, Editing, Forms, HTML, JavaScript, Media, Networking, Performance, Rendering, SVG, Security, Web API, Web Extensions, Web Inspector, WebAssembly, WebDriver, WebGL, WebGPU, and WebRTC.
The current Safari Technology Preview release is compatible with machines running macOS Tahoe and macOS Golden Gate, the newest version of macOS.
The Safari Technology Preview update is available through the Software Update mechanism in System Preferences or System Settings to anyone who has downloaded the browser from Apple's website. Complete release notes for the update are available on the Safari Technology Preview website.
Apple's aim with Safari Technology Preview is to gather feedback from developers and users on its browser development process. Safari Technology Preview can run side-by-side with the existing Safari browser and while it is designed for developers, it does not require a developer account to download and use.
