## Major changes
### Refactored Dispatch Between `wgpu-core` and `webgpu`
The crate `wgpu` has two different "backends", one which targets webgpu in the browser, one which targets `wgpu_core` on native platforms and webgl. This was previously very difficult to traverse and add new features to. The entire system was refactored to make it simpler. Additionally the new system has zero overhead if there is only one "backend" in use. You can see the new system in action by using go-to-definition on any wgpu functions in your IDE.

### Render and Compute Passes Now Properly Enforce Their Lifetime
A regression intoduced in 23.0.0 caused lifetimes of render and compute passes to be incorrectly enforced. While this is not
a soundness issue, the intent is to move an error from runtime to compile time. This issue has been fixed and restored to the 22.0.0 behavior.
### The `diagnostic(…);` directive is now supported in WGSL
Naga now parses `diagnostic(…);` directives according to the WGSL spec. This allows users to control certain lints, similar to Rust's `allow`, `warn`, and `deny` attributes.
