Apple has released Safari Technology Preview 162, the most recent version of their developer preview web browser. This version allows developers and other interested users to try out features that may or might not be included in future public releases of Safari.
Safari Technology Preview version 162 is now available for macOS Ventura 13.2 or later, and macOS Monterey with Safari 16.2. This update includes bug fixes and performance improvements for Web Inspector, CSS, Scrolling, Gamepad API, Media, Web API, and Accessibility.
Both macOS Monterey and macOS Ventura have a preview, but macOS Big Sur does not have a preview.
The Safari Technology Preview is intended for developers and advanced users; however, it may be used alongside Apple's new Safari browser release. The app does not require a developer account to download and install.
