- Ensure that `Features::TIMESTAMP_QUERY` is set when using timestamp writes in render and compute passes. By @ErichDonGubler in [#6497](https://github.com/gfx-rs/wgpu/pull/6497).
- Check for device mismatches when beginning render and compute passes. By @ErichDonGubler in [#6497](https://github.com/gfx-rs/wgpu/pull/6497).
- Lower `QUERY_SET_MAX_QUERIES` (and enforced limits) from 8192 to 4096 to match WebGPU spec. By @ErichDonGubler in [#6525](https://github.com/gfx-rs/wgpu/pull/6525).
- Allow non-filterable float on texture bindings never used with samplers when using a derived bind group layout. By @ErichDonGubler in [#6531](https://github.com/gfx-rs/wgpu/pull/6531/).
