## [0.29.0] - 2026-08-27

### Added

- **`DeviceProvider.Features()`** — returns `gputypes.Features` bitfield of optional device capabilities. Enables consumers (g3d, gg) to query features like `FeatureRayQuery` without importing wgpu directly. Returns 0 if implementation does not track features (backward compatible). Matches Rust wgpu `device.features()` pattern.

### Changed

- **deps:** gputypes v0.5.2 → v0.6.0 (ray tracing types)

## [0.28.0] - 2026-08-13
