Apple Releases Safari Technology Preview 235 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 235 includes fixes and updates for CSS, Canvas, Clipboard, Editing, Encoding, Forms, HTML, JavaScript, MathML, Media, Networking, Rendering, SVG, Web API, Web Inspector, WebAssembly, and WebRTC.

The current ‌Safari Technology Preview‌ release is compatible with machines running macOS Sequoia and macOS Tahoe, 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.

No one asked, but 26.2 is right up there with standards across all competing browsers.

It’s consistently the last to implement new css stuff. It’s kind of like IE was back in the day, unfortunately.

IE, back in the day, was not following standards. Websites needed to be coded for two targets... (1) IE and (2) every other browser. That was IE's downfall.
