@@ -85,6 +85,10 @@ Changes to `Format`:
 - The following objects now use `Format` instead of `Option<Format>`: `BufferView`, `Image`, `ImageView`, `SamplerYcbcrConversion`.
 - The `block_size` method no longer returns an `Option`.
 
+Changes to memory allocation:
+- `AllocationCreateInfo::usage` and `SubbufferAllocatorCreateInfo::memory_usage` were replaced by a `memory_type_filter` field, to allow for a more flexible selection of the memory type. Additionally, `SubbufferAllocatorCreateInfo::memory_type_filter` defaults to `MemoryTypeFilter::PREFER_DEVICE` for consistency with `AllocationCreateInfo`, unlike the previous default of `MemoryUsage::Upload`.
+- `SubbufferAllocatorCreateInfo::buffer_usage` is now empty by default for consistency with `BufferCreateInfo`.

 ### Additions
