 - Support constant evaluation for `firstLeadingBit` and `firstTrailingBit` numeric built-ins in WGSL. Front-ends that translate to these built-ins also benefit from constant evaluation. By @ErichDonGubler in [#5101](https://github.com/gfx-rs/wgpu/pull/5101).
 - Add `first` and `either` sampling types for `@interpolate(flat, …)` in WGSL. By @ErichDonGubler in [#6181](https://github.com/gfx-rs/wgpu/pull/6181).
 - Support for more atomic ops in the SPIR-V frontend. By @schell in [#5824](https://github.com/gfx-rs/wgpu/pull/5824).
+- Support local `const` declarations in WGSL. By @sagudev in [#6156](https://github.com/gfx-rs/wgpu/pull/6156).
+- Implemented `const_assert` in WGSL. By @sagudev in [#6198](https://github.com/gfx-rs/wgpu/pull/6198).

+- Fix detection of shl overflows to detect aritmetic overflows. By @sagudev in [#6186](https://github.com/gfx-rs/wgpu/pull/6186).
+- Fix type parameters to vec/mat type constructors to also support aliases. By @sagudev in [#6189](https://github.com/gfx-rs/wgpu/pull/6189).
+- Accept global `var`s without explicit type. By @sagudev in [#6199](https://github.com/gfx-rs/wgpu/pull/6199).
+- Fix handling of phony statements, so they actually get emitted. By @sagudev in [#6328](https://github.com/gfx-rs/wgpu/pull/6328).
