 The gfx-rs team has published a [gfx-post] providing the overview
 of all projects in the works, and how they are connected to each other.
 
+[wgpu] has moved from [gfx-extras] to the new [gpu-alloc] and [gpu-descriptor]
+libraries by [@zakarumych]. These are backend-agnostic, which allows `wgpu`
+to now depend on `gfx-hal` directly without intermediates. Patching [gfx-rs]
+will now be easier, without the need to release every little change.
+
+Finally, all the latest [wgpu] code has landed into Gecko, and new
+features and fixes are implemented in Firefox. That allows it to run
+most of the updated [WebGPU samples].
