Apple Releases Safari Technology Preview 137 With Bug Fixes and Performance Improvements

Apple today released a new update (https://developer.apple.com/safari/download/) for Safari Technology Preview (https://www.macrumors.com/guide/safari-technology-preview/), the experimental browser Apple first introduced (http://www.macrumors.com/2016/03/30/apple-safari-technology-preview-browser/) in March 2016. Apple designed the ‌Safari Technology Preview‌ to test features that may be introduced into future release versions of Safari.

&zwnj;Safari Technology Preview&zwnj; release 137 includes bug fixes and performance improvements for Web Inspector, CSS, JavaScript, WebAssembly, Experimental Model Element, Accessibility, Web API, Content Security Policy, Media, Apple Pay (https://www.macrumors.com/roundup/apple-pay/), and Web Extensions.





The current &zwnj;Safari Technology Preview&zwnj; release is built on the Safari 15.4 update and it includes Safari 15 features introduced in macOS Monterey (https://www.macrumors.com/roundup/macos-12/). There's a new streamlined tab bar with support for Tab Groups to organize tabs, along with improved support for Safari Web Extensions. Apple in &zwnj;Safari Technology Preview&zwnj; 135 added 120Hz refresh rates for the new 14 and 16-inch MacBook Pro models.





Live Text allows users to select and interact with text in images on the web, but &zwnj;macOS Monterey&zwnj; and an M1 (https://www.macrumors.com/guide/m1/) Mac is required. There's also Quick Notes support for adding links and Safari highlights to remember important information and ideas. The new &zwnj;Safari Technology Preview&zwnj; update is available for both macOS Big Sur and &zwnj;macOS Monterey&zwnj;, the newest version of the Mac operating system.





The &zwnj;Safari Technology Preview&zwnj; update is available through the Software Update mechanism in System Preferences to anyone who has downloaded the browser (https://developer.apple.com/safari/download/). Full release notes for the update are available on the Safari Technology Preview website (https://developer.apple.com/safari/technology-preview/release-notes/).





Apple's aim with &zwnj;Safari Technology Preview&zwnj; is to gather feedback from developers and users on its browser development process. &zwnj;Safari Technology Preview&zwnj; can run side-by-side with the existing Safari browser and while designed for developers, it does not require a developer account to download.<div class="linkback">Tag: Safari Technology Preview (https://www.macrumors.com/guide/safari-technology-preview/)</div>
