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 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.

I wonder when WebGPU will be back? There are some demos/examples on the web, but in the current Safari, you’re not able to enable WebGPU.

I’m hoping Apple will do whatever they need to do to so StreamYard will enable support for Safari on Mac.

StreamYard tells me that Safari causes issues with WebRTC so they disabled support. Not sure what needs to happen but waiting, nonetheless…

What does WebGPU do for us?
It’s an API that exposes the capabilities of GPU hardware for the Web.
Here’s an article that starts by defining the difference between WebGL and WebGPU.
One area that may benefit, for example, is browser based games.

EDIT: And, as someone else here mentioned in another thread, it was proposed by Apple and they said it works like Metal, thus increasing the number of Metal aware developers as a side-effect.

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!

Safari needs all the help it can get.

Attention.. it should have all the attention it warrants, because Safari is one of the core experiences in macOS. It is not a side project. That a lot of it can be buggy is Apple taking consumer tolerance towards software for granted.

Just like the rest of Apple's Software. (Music, Podcasts...)

This is true. How strong the foundations of macOS must be to have allowed them to coast on it for this long while continually screwing things up (and fixing, too). I do wish they paid real attention to macOS experience.

Messages come to mind. It is a joke on both iOS and macOS, but on macOS it is plain pathetic. I cannot, even after multiple macOS iterations, delete multiple message threads in one go. My messages do not sync between devices - incoming works, outgoing works, but I have to delete on every device manually - deletion does not sync.

Music - people made iTunes the butt of several jokes and memes, maybe rightly so, but the Music app is no better. It has lost its simplicity on both macOS and iOS. I often find myself hunting.

Podcasts, can't say as I do not use it.

I really do have problems with safari right now. On iOS and also on MacOS. Some button or forms don't work occasionally. Anyone else noticed this problem?

On my iPad (latest iOS) 12" Pro. Safari stalls every now and than. Page loading takes forever. Kill Safari App, restart it - the same page loads within a blink of an eye.

Other pages don't work neither on Safari iOS or on Safari macOS. Cookie banners are often rendered invisible. Firefox, Chromium and Edge work flawlessly.

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.

On safari preview uncheck prefer page rendering updates near 60fps and then fully quit safari and restart. You should see 120fps on ufotest

Full screen videos in Reddit half fixed. Like literally. You now see half the video in the top half of the screen over a full screen window of the site itself.
