Apple released a new version of the Safari Technology Preview today. This is an experimental browser that Apple first released in March 2016. Apple made the Safari Technology Preview so that it could test features that might be added to Safari in the future.
Among the features included in the newest Safari Technology Preview version are Live Text, Passkeys, Web Extension enhancements, and more, all of which will be available in macOS Ventura.
It is now possible to use Safari Technology Preview on Macs running macOS 13 Ventura, as opposed to previous versions, although it is not compatible with Macs running macOS 10 Big Sur.
The Safari Technology Preview update can be accessed by anyone who has previously downloaded the browser through the Software Update mechanism found in the System Preferences menu. On the website for Safari Technology Preview, you may see the complete release notes for the upgrade.
The Safari Technology Preview is an effort by Apple to get feedback from developers and users on its browser development process. In spite of being intended for developers, Safari Technology Preview does not require a developer account in order to be downloaded and used in conjunction with the current Safari browser.
