@@ -68,6 +68,7 @@ Bottom level categories:
 - Validate pipeline layout `immediate_size` and fix its calculation when there are multiple immediate variables. Now it must be >= required size of the shader entry point. By @beicause in [#9711](https://github.com/gfx-rs/wgpu/pull/9711).
 - [`immediate_address_space`](https://www.w3.org/TR/WGSL/#language_extension-immediate_address_space) WGSL language extension is implemented. By @beicause in [#9711](https://github.com/gfx-rs/wgpu/pull/9711).
 - `TextureFormat::is_srgb()` has been renamed to `TextureFormat::has_srgb_suffix()` to clarify its function. By @kpreid in [#9758](https://github.com/gfx-rs/wgpu/pull/9758).
+- Remove the never-constructed `CreateBlasError::InvalidAabbStride` variant. `create_blas` takes no stride, so it could never be produced; AABB stride is validated at build time as `BuildAccelerationStructureError::InvalidAabbStride`. By @mstampfli in [#9935](https://github.com/gfx-rs/wgpu/pull/9935).
