Author: EriKWDev

@@ -196,6 +196,7 @@ By @cwfitzgerald in [#8162](https://github.com/gfx-rs/wgpu/pull/8162).
 - If the shader source contains control characters, naga now replaces them with U+FFFD ("replacement character") in diagnostic output. By @andyleiserson in [#8049](https://github.com/gfx-rs/wgpu/pull/8049).
 - Add f16 IO polyfill on Vulkan backend to enable SHADER_F16 use without requiring `storageInputOutput16`. By @cryvosh in [#7884](https://github.com/gfx-rs/wgpu/pull/7884).
 - For custom Naga backend authors: `naga::proc::Namer` now accepts reserved keywords using two new dedicated types, `proc::{KeywordSet, CaseInsensitiveKeywordSet}`. By @kpreid in [#8136](https://github.com/gfx-rs/wgpu/pull/8136).
+- **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).
