+- `DescriptorPool::allocate_descriptor_sets` is now validated, and returns `DescriptorPoolAlloc` objects.
+- `DescriptorSetAllocator::allocate` returns `Validated<VulkanError>` as its error type.
+- `UnsafeDescriptorSet::update` is now partially validated, and takes slices instead of iterators.
+- `UnsafeDescriptorSet` now owns its allocation.
 
 Changes to render pass objects:
