#### Bindless support improved and validation rules changed.
Metal support for bindless has significantly improved and the limits for binding arrays have been increased.
Previously, all resources inside binding arrays contributed towards the standard limit of their type (`texture_2d` arrays for example would contribute to `max_sampled_textures_per_shader_stage`). Now these resources will only contribute towards binding-array specific limits:
- `max_binding_array_elements_per_shader_stage` for all non-sampler resources
- `max_binding_array_sampler_elements_per_shader_stage` for sampler resources.

// Continue pass recording.
cpass.set_bindgroup(...);
```
Previously, a set pipeline (or other resource) had to outlive pass recording which often affected wider systems,
meaning that users needed to prove to the borrow checker that `Vec<wgpu::RenderPipeline>` (or similar constructs)
aren't accessed mutably for the duration of pass recording.
Furthermore, you can now opt out of `wgpu::RenderPass`/`wgpu::ComputePass`'s lifetime dependency on its parent `wgpu::CommandEncoder` using `wgpu::RenderPass::forget_lifetime`/`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::RenderPass`/`wgpu::ComputePass` is pending for a given `wgpu::CommandEncoder`, creation of a compute or render pass is an error and invalidates the `wgpu::CommandEncoder`.
`forget_lifetime` can be very useful for library authors, but opens up an easy way for incorrect use, so use with care.
This method doesn't add any additional overhead and has no side effects on pass recording.

The literals `1` and `0` are abstract integers, and the expression
`vec2(1, 0)` is an abstract vector. However, Naga recognizes that
it can convert that to the concrete type `vec2<f32>` to satisfy

### New Features
#### General
- Added `DownlevelFlags::VERTEX_AND_INSTANCE_INDEX_RESPECTS_RESPECTIVE_FIRST_VALUE_IN_INDIRECT_DRAW` to know if `@builtin(vertex_index)` and `@builtin(instance_index)` will respect the `first_vertex` / `first_instance` in indirect calls. If this is not present, both will always start counting from 0. Currently enabled on all backends except DX12. By @cwfitzgerald in [#4722](https://github.com/gfx-rs/wgpu/pull/4722).
- Added support for the `FLOAT32_FILTERABLE` feature (web and native, corresponds to WebGPU's `float32-filterable`). By @almarklein in [#4759](https://github.com/gfx-rs/wgpu/pull/4759).

- `SurfaceConfiguration` now exposes `desired_maximum_frame_latency` which was previously hard-coded to 2. By setting it to 1 you can reduce latency under the risk of making GPU & CPU work sequential. Currently, on DX12 this affects the `MaximumFrameLatency`, on all other backends except OpenGL the size of the swapchain (on OpenGL this has no effect).
