On July 27, Apple released Safari Technology Preview 150 with multiple bug fixes and performance improvements after several days of releasing version 149.
If you already have the complete installation of the Safari Technology Preview from the Apple Developer Center, the latest preview update is now available to download from the System Preferences of your eligible Mac running on macOS Monterey or macOS Ventura. It is no longer available for macOS Big Sur.
Apple’s primary reason behind the testing of new features on its browser is to get feedback from developers, for which, users don’t need to download any special developer account to make it accessible.
For those who are unfamiliar, Safari Technology Preview is mainly aimed at more advanced Mac users who want to try out the upcoming web technologies in the Safari browser on macOS by getting the latest layout technologies, visual effects, and developer tools, and more without altering the primary Safari browser.
You can know more about the new changes, features, and bug fixes in the official release notes about Safari Technology Preview 150.
