Chrome 145 introduces the WGSL subgroup_uniformity extension, which improves uniformity analysis at the subgroup level, allowing more values to be considered subgroup-uniform. An experimental synchronous buffer mapping feature (mapSync()) is now available in workers to reduce friction between WebGPU and application code. Dawn updates include feature replacements (TextureFormatTier1 superseding R8UnormStorage), nightly binary releases on GitHub, and ExternalTexture support in Emdawnwebgpu.

What's New in WebGPU (Chrome 145)

Experimental synchronous buffer mapping in workers

I don’t know why they call this WebGPU
It’s really a cross-platform API for GPU that we can use for building Software as well.
It’s Amazing Tech and should not be called limited to Web only
