Apple has released Safari Technology Preview 251, an update for its experimental browser that includes bug fixes and performance improvements.

Apple has not provided specific notes regarding the changes in version 251. The current release is compatible with machines running macOS Tahoe and macOS Golden Gate.

The experimental browser, first introduced in March 2016, allows users to test features planned for future versions of the Safari browser. Apple uses the platform to gather feedback from developers and users regarding its browser development process.

Safari Technology Preview can run side-by-side with the existing Safari browser. While designed for developers, the browser does not require a developer account to download and use. The update is available through the Software Update mechanism in System Preferences or System Settings for those who previously downloaded the browser from Apple's website.
