Apple Releases Safari Technology Preview 128 With Bug Fixes and Performance Improvements

Wednesday July 21, 2021 4:36 pm 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 128 includes bug fixes and performance improvements for Web Inspector, CSS, JavaScript, Live Text, Media, Performance API, and Web API.

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.

Notably, this release includes the same changes to the tab layout that were made in macOS Monterey beta 3, now defaulting to separate tab and address bars. The streamlined layout with a single bar remains available in the View menu through the "Show Separate Tab Bar" option.

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.

No new beta 3 tab design?

It does have it! You can find it in View -> Show Separate Tab Bar.
There’s also an option to disable colors in the tab bar in preferences (Advanced -> Show color in tab bar).

Personally I like the new combined layout, but I think having these options is even better.

Did this bring Tab Groups back?

This is back, too.

Thank you! Solid update. Keep up the good work Apple & the developers.

Don’t comment on how “solid” an update is when you could not have tested it.

From the changelog:

Note: Tab Groups do not sync in this release.

Not sure if syncing is what you mean by “share”. ?‍♂️

yeah that's what i meant. thanks.

Seems like font rendering in one row tabs was fixed.
Tab dragging in separate tab bar needs work though, cursor jumps to middle of tab while dragging.

Its going to take some getting used to , it was better once I turned off the color in tab bar, one site was a dark grey and the next one was a neon orange, it was a bad day for having eyes.

Launched with the new b3 tab design as default. I think I prefer it this way, but I can see why laptop users would want to keep the more compact design
