Safari Technology Preview release 17 includes bug fixes and updates for Safari Extensions, Custom Elements, Web APIs, Input Events, URL Parser, Fetch API, JavaScript, Web Inspector, CSS, Media, Networking, and more.
The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store to anyone who has downloaded the browser. Full release notes for the update are available on the Safari Technology Preview website.
Apple's goal with Safari Technology Preview is to receive 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 designed for developers, it does not require a developer account to download.
