+Voxel Bunny rendering with conservative rasterization
+
+[wgpu] is a [WebGPU] implementation in Rust. It is safe, efficient,
+and portable: can target both native (Vulkan/D3D/Metal) and the Web.
+
+Most progress in April was focused around [WGSL] shaders and validation.
+[naga] has seen a lot of improvements in the SPIR-V and WGSL parsing, as well
+as backend code generation. Most importantly, it now fully validates both
+statements and expressions. No more accidental foot shots from adding vec2
+and vec3 in the shaders!
+
+The last and the biggest (in terms of shader complexity) example - "water"
+has been successfully ported to WGSL :tada:.
+
+A small addition to our native-only features - conservative rasterization
+feature - was added by [@wumpf] and demonstrated on a voxel bunny :rabbit2:
