[ Gearbest Technology News]Apple launched the Safari Technology Preview 221 version on June 11, the latest iteration of its experimental browser for developers and early users. The update focuses on fixing known issues and improving overall performance, while extending compatibility support for Apple's future operating systems.
According to official release notes, Safari Technology Preview 221 has been improved for several key areas. The enhancement of Accessibility is aimed at improving the user experience of users with special needs; the optimization of Forms and Media modules focuses on page interaction fluency and multimedia content loading efficiency. In addition, the adjustments to JavaScript engine, PDF rendering and WebRTC real-time communication functions show Apple's continuous investment in web application compatibility and cross-platform collaboration capabilities.
In terms of developer tools, the update of Web Inspector (web page inspector) provides a more efficient toolchain for debugging code, while the extension of Web API may indicate the future support direction of Safari for emerging web standards. Apple emphasized that this update did not introduce major new features, but instead focused on stability and lay the foundation for the technology that will be implemented soon.
It is worth noting that Safari Technology Preview 221 has explicitly supported macOS Sequoia and macOS Tahoe, which has not yet been officially released. The latter is expected to be launched later in 2025, and the advance adaptation of this preview version indicates that Apple is accelerating testing of its browser's deep integration with the next-generation operating system. Users can download the preview version for free through Apple's official website and run it in parallel with the existing Safari browser, so you can experience cutting-edge functions without a developer account.
