Apple on Thursday released Safari Technology Preview 126, the latest version of their developer preview web browser. The preview version of Apple’s popular browser offers developers and other interested users the ability to try out features that may or may not, debut in future public release versions of Safari.
Safari Technology Preview release 126 is built on the new Safari 15 update included in macOS Monterey, and as such, it includes several Safari 15 features.
Safari Technology Preview Release 126 is now available for download for macOS Big Sur and betas of macOS Monterey. If you already have Safari Technology Preview installed, you can update in the Software Update pane of System Preferences on macOS.
Many of the new Safari 15 features are now available in Safari Technology Preview 126:
Streamlined tab bar. Use Tab Groups to save and organize your tabs. Experience the new design. Test your site. Experiment with theme-color.
Live Text. Select and interact with text in images on the web in macOS Monterey betas on M1 Macs.
Improved Safari Web Extensions. Try out the support for
declarativeNetRequest, which expanded to 150K content blocking rules and non-persistent background pages for improved performance.
Quick Notes. Add links and Safari highlights to remember important information or ideas on the web in macOS Monterey betas.
WebGL 2. Try out the improved 3D graphics performance of WebGL running on top of Metal via ANGLE.
If you see bugs or unexpected behavior with the interface of Safari Technology Preview, please file Feedback in Apple’s Feedback Assistant. If you come across an implementation bug in web technology, or have a request, please file a ticket at bugs.webkit.org.
While the preview is intended for use by developers and advanced users, in order to provide Apple with feedback on the development of the Safari browser, it can be run side-by-side with the release version of Safari. The app doesn’t require a developer account to download and install. For more information, visit the Safari Technology Preview website.
