safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced over two years ago in March of 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.

Today's Safari Technology Preview 59 update includes support for Intelligent Tracking Prevention 2.0, which Apple announced on stage at the Worldwide Developers Conference. The feature prevents social widgets from tracking you without your permission and introduces other tracking prevention updates.

Apple says there are several known issues with the new release on macOS Mojave.

Text does not render properly in the Smart Search Field when in Dark Mode, and customers who are running the update on macOS Mojave beta 2 will need to login to websites when restarting the application or could be required to log in again on some websites when launching a new window.

Safari Technology Preview release 59 also includes bug fixes and feature improvements for Web Animations, Payment Request, JavaScript, Editing, Storage Access API, Security, Service Workers, Compatibility, WebRTC, Web API, Media, Web Inspector, Accessibility, and iCloud Keychain Password Manager.

The new Safari Technology Preview update is available for both macOS High Sierra and macOS Mojave, the newest version of the Mac operating system that's currently being beta tested by developers.

The Safari Technology Preview update is available through the Software Update mechanism in macOS to anyone who has downloaded the browser. Full release notes for the update are available on the Safari Technology Preview website.

Apple's aim with Safari Technology Preview is to gather 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.

I'm always impressed by how more detailed are the release notes for Safari Technology Preview than for any other Apple update.
