The latest version of Safari Technology Preview is here for anyone who wants to mess around with some of its latest experimental features.
Today, Apple released Safari Technology Preview 200. The latest version doesn’t include any major features that end-users will notice but does include a number of notable updates for the underlying technology that powers the browser.
The latest version of Safari Technology Preview is an experimental version of Safari for users running a Mac that currently has macOS Sonoma or the upcoming macOS Sequoia — which is giving a huge upgrade to Safari — installed. The preview allows developers and the generally curious to test out the latest and greatest features of Apple’s browser and provide feedback to the company before the public version goes live for everyone else.
