Apple Releases Safari Technology Preview 129 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 release 129 includes bug fixes and performance improvements for Web Inspector, CSS, Scrolling, Rendering, WebAssembly, Web API, Platform Features, IndexedDB, Media, WebGL, and WebCrypto.
Apple says that on macOS Big Sur, this release requires enabling the GPU Process: Media option from the Experimental Features setting in the Develop menu. Turning on the option addresses issues with streaming services.
The current Safari Technology Preview release is built on the new Safari 15 update included in macOS Monterey, and as such, it includes several Safari 15 features. 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 the macOS Monterey beta 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 that's set to release this fall.
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.

But, it looks like tab groups don’t sync.
Forbes ran an article from earlier this year showing Chrome with an "Energy Impact" number 10x higher than Safari. It also mentioned the test device (M1 MacBook Pro) gets warm running Chrome but stays cold with Safari... which means Chrome is likely pushing the CPU hard enough that it will drop the clock speed to manage temperatures on some hardware. When that happens it will start getting *really* slow (I'm guessing this is why Chrome feels noticeably slower than Safari for me).
I'm sure Chrome has improved, they're working on it continuously, but I doubt it's improved that much.
And Safari isn't sitting still either. Safari 15 is even faster and uses less power than Safari 14.
