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


Safari Technology Preview release 134 includes bug fixes and performance improvements for Web Inspector, CSS, CSS Font Loading API, Scrolling, Rendering, Dialog Element, WebAssembly, JavaScript, Web API, WebGL, Media, WebRTC, Accessibility, Private Click Measurement, and Web Extensions.

The current Safari Technology Preview release is built on the Safari 15.4 update and it includes Safari 15 features introduced in macOS Monterey. There's a new streamlined tab bar with support for Tab Groups to organize tabs, along with improved support for Safari Web Extensions.

Live Text allows users to select and interact with text in images on the web, but macOS Monterey and an M1 Mac is required. There's also Quick Notes support for adding links and Safari highlights to remember important information and ideas. The new Safari Technology Preview update is available for both macOS Big Sur and macOS Monterey, the newest version of the Mac operating system.

The Safari Technology Preview update is available through the Software Update mechanism in System Preferences 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.

They should implement this ASAP. This literally fixes any complaints I've had about the new SideBar design by keeping it exactly the same on the Start Page, and then collapsing it when navigating away. This is a perfect compromise and IMO shows that more people felt the same way. It's great to see stuff like this. With this change it makes Safari almost exactly like it was prior and still adds all of the new features with extensions and the new Start page. Good stuff!
