 ### New Features
 
 #### General
 
 - Added mesh shader support to `wgpu`, with examples. Requires passthrough. By @SupaMaggie70Incorporated in [#7345](https://github.com/gfx-rs/wgpu/pull/7345).
-
 - Added support for external textures based on WebGPU's [`GPUExternalTexture`](https://www.w3.org/TR/webgpu/#gpuexternaltexture). These allow shaders to transparently operate on potentially multiplanar source texture data in either RGB or YCbCr formats via WGSL's `texture_external` type. This is gated behind the `Features::EXTERNAL_TEXTURE` feature, which is currently only supported on DX12. By @jamienicol in [#4386](https://github.com/gfx-rs/wgpu/issues/4386).
+- `wgpu::Device::poll` can now specify a timeout via `wgpu::PollType::Wait`. By @wumpf in [#8282](https://github.com/gfx-rs/wgpu/pull/8282) & [#8285](https://github.com/gfx-rs/wgpu/pull/8285)
+
+#### naga
+
+- Expose `naga::front::wgsl::UnimplementedEnableExtension`. By @ErichDonGubler in [#8237](https://github.com/gfx-rs/wgpu/pull/8237).

 - **BREAKING**: Previously the WGSL storage-texture format `rg11b10float` was incorrectly accepted and generated by naga, but now only accepts the the correct name `rg11b10ufloat` instead. By @ErikWDev in [#8219](https://github.com/gfx-rs/wgpu/pull/8219).
 - The [`source()`](https://doc.rust-lang.org/std/error/trait.Error.html#method.source) method of `ShaderError` no longer reports the error as its own source. By @andyleiserson in [#8258](https://github.com/gfx-rs/wgpu/pull/8258).
 - naga correctly ingests SPIR-V that use descriptor runtime indexing, which in turn is correctly converted into WGSLs binding array. By @hasenbanck in [8256](https://github.com/gfx-rs/wgpu/pull/8256).
+- naga correctly ingests SPIR-V that loads from multi-sampled textures, which in turn is correctly converted into WGSLs texture_multisampled_2d and load operations. By @hasenbanck in [8270](https://github.com/gfx-rs/wgpu/pull/8270).
+- naga implement OpImageGather and OpImageDrefGather operations when ingesting SPIR-V. By @hasenbanck in [8280](https://github.com/gfx-rs/wgpu/pull/8280).

 - Fixed a bug where access to matrices with 2 rows would not work in some cases. By @andyleiserson in [#7438](https://github.com/gfx-rs/wgpu/pull/7438).
 
 ##### EGL
 
 - Fixed unwrap failed in context creation for some Android devices. By @uael in [#8024](https://github.com/gfx-rs/wgpu/pull/8024).
