Apple Releases Safari Technology Preview 97 With Bug Fixes and Performance Improvements

by

safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced three years ago 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 97 includes bug fixes and performance improvements for Resize Observer, WebAuthn, Web Animations, Web Inspector, Rendering, Back-Forward Cache, SVG, Clipboard API, CSS, Remote Playback API, Media, JavaScript, Picture-in-Picture Web API, WebAssembly, and Web API.

The new ‌Safari Technology Preview‌ update is available for both macOS Mojave and MacOS Catalina, the newest version of the Mac operating system that was released in October.

The ‌Safari Technology Preview‌ update is available through the Software Update mechanism in the Mac App Store 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.

Apple needs to be way, way more aggressive in building a truly privacy-oriented browser. They could borrow some cues from Mozilla/FF, Brave, etc.

input type=date

Also, a proper built-in ad blocker, not the paid crap they offer in the App Store. The rendering engine is ancient, one of the slowest if not the slowest. Media playback controls have been broken for years, etc, etc.
Yes, Input Type to be one. Important and possibly the only I would complain about.

Not sure what is wrong with ad blocker. There are free alternative, and Safrai has one of the best Ad Blocking performance in all browsers. ( Not sure if Firefox or Chrome has caught up yet )

What Media Playback control is broken? Have not witness and heard of any.



As much as I hate Google, I wish they would use Blink, performance is very superior.

Hover over a youtube video several times you'll break controls in no time.

On meet, most popular business conferencing web app to date, you can't even share screen, and 2 months ago it didn't even work with Safari.

If anything Safari has been out performing Chrome / Blink is most Web Page test and Lightweight Web App test. It falls behind in ridiculous heavy web app / JS benchmarks which 99.9% of users dont use.

Watch more YouTube video than I ever have to, never had control fail me once. Even if I did hover over it a lot.

I assume you are talking about Meet in GSuite from Google. Then I am not even surprised it didn't work on Safari at first.

What HTML5 features you cared about is missing in the current Safari ? We are way past the IE era, 99.9% of what we need are already included in both Safari and Chrome.

Anyone have https://html5test.com results?
500/555. Usual caveats apply: It's not really going to change; html5test was last updated four years ago.
