 - Added `as_hal` for `Buffer` to access wgpu created buffers form wgpu-hal. By @JasondeWolff in [#5724](https://github.com/gfx-rs/wgpu/pull/5724)
-- Unconsumed vertex outputs are now always allowed. Removed `StageError::InputNotConsumed`, `Features::SHADER_UNUSED_VERTEX_OUTPUT`, and associated validation. By @Imberflur in [#5531](https://github.com/gfx-rs/wgpu/pull/5531)
+- `include_wgsl!` is now callable in const contexts by @9SMTM6 in [#5872](https://github.com/gfx-rs/wgpu/pull/5872)
 - Added memory allocation hints to `DeviceDescriptor` by @nical in [#5875](https://github.com/gfx-rs/wgpu/pull/5875)
     - `MemoryHints::Performance`, the default, favors performance over memory usage and will likely cause large amounts of VRAM to be allocated up-front. This hint is typically good for games.
     - `MemoryHints::MemoryUsage` favors memory usage over performance. This hint is typically useful for smaller applications or UI libraries.

+- HLSL & MSL output can now be added conditionally on the target via the `msl-out-if-target-apple` and `hlsl-out-if-target-windows` features. This is used in wgpu-hal to no longer compile with MSL output when `metal` is enabled & MacOS isn't targeted and no longer compile with HLSL output when `dx12` is enabled & Windows isn't targeted.
