Apple Releases Safari Technology Preview 213 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 213 includes fixes and updates for CSS, Editing, Forms, HTML, JavaScript, Media, Networking, PDF, Rendering, Storage, SVG, Tables, Text, Web Animation, Web API, Web Extensions, Web Inspector, and WebRTC.

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

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.

It would be nice if they would actually limit the RAM use of Safari a bit, or release it after some idle time. My m1 system with 32 gigs of RAM slows down noticeably once Safari gobbles up 20 gigs and more; for like six windows and maybe two or three dozen tabs. No matter system or the OS. :/

Huh? The changelog is extensive and always is for these Safari updates - did you actually review the list?

It would be great if this iteration of Safari would sync with the others (e.g. open pages across devices).

Reason being, more often than not it (Safari Tech Preview) is much more stable, for me, then the regular release version of Safari.

Logically it should not be so, but it is ?‍♂️
It's a Tech Preview for a reason — testing, not for production use.

If someone chooses to use it for everyday browsing, that is their choice.

It's smart to keep it isolated from
the "stable" Safari release, as nobody wants to have lost or corrupted data and bookmarks from bugs.

One idea for you — use a third-party extension that does the syncing for you, and have it installed in both.
