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

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 Feature
‌Safari Technology Preview‌ 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, 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. Apple in ‌Safari Technology Preview‌ 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 ‌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.

Wow, this technology preview release really does add 120hz, even on the released macOs 12.1! Side by side this preview vs. the 12.1 release-included safari shows a BIG difference in scrolling, particularly when browsing macrumors. I was going to install macOS 12.2 beta, but glad I tried this first!

Ha. Been a while for that one. We’ll played.

Do we happen to know the origin of that phrase? I would love to know who first penned that. I want to say it could have been as long ago as 15 years - maybe more - and I’m 100% certain they meant it. To think how far it has traveled. Kind of one of the earlier memes. If not one of the more organic.
Changelogs from Safari updates in years past included it. It became a huge joke here.
