Apple has released Safari Technology Preview 227, an experimental browser for testing upcoming Safari features. This update brings fixes and improvements across a wide range of web technologies including Accessibility, CSS, HTML, JavaScript, and WebAssembly. The new version is compatible with macOS Sequoia and the upcoming macOS Tahoe. Users can download Safari Technology Preview from Apple's website and update it via the Software Update mechanism. This experimental browser allows users to test features before they are released in the stable Safari version. Apple uses Safari Technology Preview to gather feedback from developers and users on its browser development. It can be run alongside the regular Safari browser. Anyone can download and use Safari Technology Preview without needing a developer account. The goal is to provide a platform for early access and testing of new web standards and Safari capabilities. Detailed release notes are available on the Safari Technology Preview website.
