 - Removed three features from `wgpu-hal` which did nothing useful: `"cargo-clippy"`, `"gpu-allocator"`, and `"rustc-hash"`. By @kpreid in [#8357](https://github.com/gfx-rs/wgpu/pull/8357).
 - `wgpu_types::PollError` now always implements the `Error` trait. By @kpreid in [#8384](https://github.com/gfx-rs/wgpu/pull/8384).
 - The texture subresources used by the color attachments of a render pass are no longer allowed to overlap when accessed via different texture views. By @andyleiserson in [#8402](https://github.com/gfx-rs/wgpu/pull/8402).
+- The `STORAGE_READ_ONLY` texture usage is now permitted to coexist with other read-only usages. By @andyleiserson in [#8490](https://github.com/gfx-rs/wgpu/pull/8490).
 - Validate that buffers are unmapped in `write_buffer` calls. By @ErichDonGubler in [#8454](https://github.com/gfx-rs/wgpu/pull/8454).
