Apple Releases Safari Technology Preview 133 With Bug Fixes and Performance Improvements

Thursday September 30, 2021 10:13 am PDT by Juli Clover

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 133 includes bug fixes and performance improvements for CSS, CSS Cascade Layers, CSS Font Loading API, Accessibility, JavaScript, Web API, WebRTC, Media, WebGL, and Web and App Extensions.

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.

Other updates include WebGL 2 and new HTML, CSS, and JavaScript features.

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.

RIP, MacBook Ultra

Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

Of course it was intentional. That's how all side bars function these days.

Really? make it inferior to previous because "That's how all side bars function these days"? You should send your resume to Apple (unless you dev for them already)

Not sure if you're aware but there's "Show More" button besides Reading List on start page, which I think shows all of the entries and stays that way.
I find it strange that you like everything else though, personally I can't stand how broken tabs are and that we don't have a fallback to old style.

Yeah, the whole Tab situation is a mess, too. I use Nitefall ('https://apps.apple.com/us/app/nitefall-dark-mode-for-safari/id1575190591') on macOS and Noir ('https://apps.apple.com/us/app/noir-dark-mode-for-safari/id1581140954') on iOS/iPadOS. That seems to make the Tabs a little more palatable. Plus the whole Dark Mode dealio..

And yes, the Show More option is helpful. But even still, everything in Safari just stays in a small section in the middle instead of being dynamic and using up the rest of the space on the page. It's better than nothing, I guess. But that doesn't have the search feature like it does in the SideBar. Sometimes I need to reference something that's maybe 6-8 months old or older and searching for it is easy- er, was easy.

Yes, that is what I'm referring to, and then that allows you to keep the SideBar open on the Start Page and have it NOT be there when you navigate away to any other page. And yes, the Start Page does show the most recent items from my Reading List, but I tend to go back further than the 12 listings it shows.

I honestly DO like everything else about Safari 15. I like the extensions and I love the new Start Page and all of the available content and how it syncs across everywhere. That's great! But the hate of now having to go thru many steps to scroll through my Reading List just makes it all a wash for me. 😕
