Apple has released Safari Technology Preview 237, an experimental browser update designed to test features planned for future Safari releases. The update includes fixes and improvements across multiple areas including Accessibility, CSS, DOM, HTML, Networking, Rendering, SVG, Web API, Web Authentication, Web Extensions, Web Inspector, and WebRTC.

This release is compatible with machines running macOS Sequoia and macOS Tahoe, Apple's newest operating system. The 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 are available on the Safari Technology Preview website.

Apple created Safari Technology Preview to gather feedback from developers and users during the browser development process. The browser can run side-by-side with the existing Safari browser and while it's designed for developers, it doesn't require a developer account to download and use. This approach allows Apple to test new features and gather real-world feedback before incorporating them into the stable Safari browser releases.
