Is there a comprehensive list of what has changed in Metal 3.1? The API diff is not really helpful and there is no such document for the shading language. From a cursory glance, this is what I have noticed:

curve support for raytracing
bfloat support on the GPU
option to specify vertex stride at the time of binding rather than as property of the render pass
linked function support for mesh shading pipeline (essentially VK_EXT_shader_object from what I understand)?

Anything substantial changes that I have missed?

There’s some new functionality to help with animation, it seems: CAMetalDisplayLink

Apple has always had VK_EXT_shader_object, it's Vulkan that locked everything down into rigid PSO. I would assume like ray-tracing, that's the ability to splice in bits of code.

There's also multi-level instancing for ray tracing acceleration structures.

And indirect builds for instance acceleration structures.
