Apple Releases Safari Technology Preview 104 With Bug Fixes and Performance Improvements

by

safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced four 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 104 includes extensive bug fixes and performance improvements for Web Inspector, Web API, CSS, Web Animations, Intersection Observer, Media, WebRTC, WebAuthn, and Safari Extensions.

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 2019.

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.

Google Classroom is still broken. Attachments will fail to load when "Prevent cross-site tracking" is enabled.
That just means Google is doing its thing trying to get around privacy settings. Why is that Safari’s problem?

While you might be correct, an average user will switch to a browser that works rather than put up with incompatibility issues.

Google Classroom is increasingly popular these days, and it works fine on Edge, Firefox, and (obviously) Chrome. Apple needs to make Safari compatible with Classroom OR ask Google to fix Classroom. Heck, Apple thanked Google for its cross-site tracking improvements.

Also, the fact that "prevent cross-site tracking" is a global setting (cannot be excluded for certain websites) means users will have to choose between lower security for all OR use different browser.

The one which gives Apple billions to make it their default search option?
I’m not sure how you think that makes googles business practices any less skeezy.

So Apple should just bite the bullet and reduce security so it can play well with Google? Right. As for the average user, they don’t even know other browsers exist.

When these are released by Apple ...does every OSX get an update via Updates/App Store?
You have to sign up. This is not safari, but a beta version, hence “technology preview”. The article says: “The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store to anyone who has downloaded the browser ('https://developer.apple.com/safari/download/'). Full release notes for the update are available on the Safari Technology Preview website ('https://developer.apple.com/safari/technology-preview/release-notes/').”


I'm having the same problem. No updates from App store on this, and I'm not seeing any way to check for updates through the Safari Tech Preview app.
It’s under Settings and this is not safari, but technology preview, you have to sign up for it

Sounds like the right approach really. You get a choice of being tracked and mined for data or don't use the product when protected.
