The Safari Technology Preview gives a glimpse into the future, testing features that might potentially find their way into the coming versions of Safari. Version 177 includes bug fixes and updates in various areas from Web Inspector, CSS, rendering to popover, media, JavaScript, Web API, accessibility, and Apple Pay.

The current Safari Technology Preview is compatible with systems running macOS Ventura and macOS Sonoma, the latest version of macOS, which Apple is currently testing.
