Settings showing WebGPU disabled and in the "Preview" category.

I have upgraded Sequoia to 15.7 (24G222) and Safari to Version 26.0.1 (20622.1.22.118.4).

The rotating cube example https://webgpu.github.io/webgpu-samples/?sample=rotatingCube won't load, the page says "navigator.gpu is not defined - WebGPU not available in this browser"

When I open Safari 26 settings and go to "feature flags" it says that the "WebGPU" and "WebGPU support for HDR" features are disabled and are marked as "Preview". See attached screenshot.

According to this blog post https://webkit.org/blog/17333/webkit-features-in-safari-26-0/#webgpu "[WebGPU] is now shipping in Safari 26.0 for macOS, iOS, iPadOS, and visionOS".

navigator.gpu requires macOS Tahoe, iOS 26, visionOS 26 or later

Mike, perhaps we should completely hide the feature on older OS versions then? "Preview" status is now inaccurate for it on macOS 15.

[Mike Wyrzykowski]

Agreed
