April 2025 monthly summary for gpuweb/cts focusing on feature delivery and bug fixes with cross-platform impact. Delivered key changes to stencil testing reliability and mappedAtCreation buffer alignment, enhancing cross-platform stability and WebGPU spec conformance.

February 2025 monthly summary for gpuweb/cts. Focused on maintaining and aligning the WebGPU CTS with the latest spec changes. Delivered a spec-aligned update to viewport validation tests to reflect that viewports may extend beyond render attachment boundaries, ensuring test results remain accurate with current WebGPU API behavior. Implemented via commit c019bac293d0473aafc758de86584d2a8ea20459: "Loosen Viewport validation tests to match spec update (#4106)". No major bugs were fixed this month for gpuweb/cts; primary emphasis was test maintenance, reliability, and alignment with updated specs to improve conformance validation.

December 2024 monthly summary for mrdoob/three.js: Implemented a robust guard for WebXR Layers initialization by validating the 'layers' feature in enabledFeatures and initializing only when supported. This prevents runtime errors when the feature is unavailable, improving stability for XR experiences across platforms. Complemented by enhanced WebXR feature testing to reduce edge-case failures and support broader device compatibility.
