Apple Releases Safari Technology Preview 204 With Bug Fixes and Performance Improvements

Apple today released a new update for Safari Technology Preview, the experimental browser that was first introduced in March 2016. Apple designed ‌Safari Technology Preview‌ to allow users to test features that are planned for future release versions of the Safari browser.

Safari Technology Preview Updated Feature 1
‌Safari Technology Preview‌ 204 includes fixes and updates for Accessibility, CSS, Forms, JavaScript, Service Workers, Web API, Web Driver, Web Extensions, and Web Inspector.

The current ‌Safari Technology Preview‌ release is compatible with machines running macOS Sonoma and macOS Sequoia, the newest version of the Mac operating system.

The ‌Safari Technology Preview‌ update is available through the Software Update mechanism in System Preferences or System Settings to anyone who has downloaded the browser from Apple's website. Complete 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 it is designed for developers, it does not require a developer account to download and use.

Same here. It’s bad. Really bad.
Odd. Sorry you’re encountering issues. I assume you’ve done the customary clear cache, delete web data, .. ? Thankfully I’ve had zero issues with Safari on Sequoia.

I wish they would push updates to Safari, stable channel, more often than they do.
I wish all the system apps could be updated outside major OS updates. Mail still wouldn’t get love outside its 8-10 year schedule but I can hope.

when will Apple stop dragging their feet on the lack of improvements that artificially make the web a second class citizen? I though the Michael Tsai blog post ('https://mjtsai.com/blog/2024/09/30/an-abridged-history-of-safari-showstoppers/') on this was illuminating and a pretty damning reason to allow non WebKit browsers.
Not just when it comes to standards there is also Apple dragging their feet every step of the way when it comes to implementing Webextensions APIs - just have a read of the WECG meeting minutes on how Apple engineers drag their feet every step fo the way, dreaming of unrealistic scenarios in justification of why they refuse to implement a particular feature that both Chrome and Firefox developers agree to. It is the reason I gave up on Safari a long time ago - I just hope that Apple is forced to open up iOS to competing web engines so it finally forces them to get their act together.

Edit: If people want to see where they are standards compliance wise they can check out this:

Given the number of tests Safari is failing Apple need more programmers getting it sorted out in a timely manner.
