 `wgpu::ComputePass` recording methods (e.g. `wgpu::ComputePass:set_render_pipeline`) no longer impose a lifetime constraint passed in resources.
 
-By @wumpf in [#5569](https://github.com/gfx-rs/wgpu/pull/5569), [#5575](https://github.com/gfx-rs/wgpu/pull/5575).
+Furthermore, you can now opt out of `wgpu::ComputePass`'s lifetime dependency on its parent `wgpu::CommandEncoder` using `wgpu::ComputePass::forget_lifetime`:  
+```rust
+fn independent_cpass<'enc>(encoder: &'enc mut wgpu::CommandEncoder) -> wgpu::ComputePass<'static> {
+    let cpass: wgpu::ComputePass<'enc> = encoder.begin_compute_pass(&wgpu::ComputePassDescriptor::default());
+    cpass.forget_lifetime()
+}
+```
+⚠️ As long as a `wgpu::ComputePass` is pending for a given `wgpu::CommandEncoder`, creation of a compute or render pass is an error and invalidates the `wgpu::CommandEncoder`.
+This is very useful for library authors, but opens up an easy way for incorrect use, so use with care.
+`forget_lifetime` is zero overhead and has no side effects on pass recording.

 ### Changes
 
 #### General
 
 - Avoid introducing spurious features for optional dependencies. By @bjorn3 in [#5691](https://github.com/gfx-rs/wgpu/pull/5691)
 
+#### Metal
+- Removed the `link` Cargo feature.
+
+  This was used to allow weakly linking frameworks. This can be achieved with putting something like the following in your `.cargo/config.toml` instead:
+  ```toml
+  [target.'cfg(target_vendor = "apple")']
+  rustflags = ["-C", "link-args=-weak_framework Metal -weak_framework QuartzCore -weak_framework CoreGraphics"]

 - Ensure render pipelines have at least 1 target. By @ErichDonGubler in [#5715](https://github.com/gfx-rs/wgpu/pull/5715)
+- `wgpu::ComputePass` now internally takes ownership of `QuerySet` for both `wgpu::ComputePassTimestampWrites` as well as timestamp writes and statistics query, fixing crashes when destroying `QuerySet` before ending the pass.
