@ -41,6 +41,7 @@ Changes to buffers:
- The `buffer_with_range(_array)` constructor of `WriteDescriptorSet` now takes `DescriptorBufferInfo` structs.
- Index buffers are now specified using the `IndexBuffer` enum instead of the `Index` trait.
- `ExternalBufferInfo::sparse` was replaced by a `flags` field.
- `Subbuffer::mapped_ptr` was replaced by `Subbuffer::mapped_slice`.
Changes to errors:
- Added new types `ValidationError` and `Validated` (enum of `ValidationError` + something else) to return errors from any function. Some existing functions have been converted to use these types, others will follow later.

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`.
- `MemoryAlloc::new` no longer returns a `Result`, and doesn't map the `DeviceMemory` automatically anymore.
- `MemoryAlloc::mapped_ptr` and `MemoryAlloc::mapped_slice[_mut]` were replaced by `MemoryAlloc::mapped_slice`, which returns a pointer.
- `MemoryAlloc::{invalidate, flush}_range` now take a `MappedMemoryRange` as argument.
Changes to synchronization primitives:
- `Event::signaled` is renamed to `is_signaled`, to match the method on `Fence`.
@ -147,6 +151,8 @@ Changes to the `khr_display` extension:
- Support for the `khr_swapchain_mutable_format` extension.
- Support for pipeline derivatives.
- Support for the `khr_get_display_properties2` extension.
- Added `DeviceMemory::{map, unmap, mapping_state, invalidate_range, flush_range}`, `MappedDeviceMemory` has been deprecated.
- Added `MemoryMapInfo`, `MemoryUnmapInfo`, `MappingState` and `MappedMemoryRange`.
### Bugs fixed
@ -160,6 +166,8 @@ Changes to the `khr_display` extension:
- vulkano-shaders: Use a placeholder name instead of erroring out, when the shader doesn't contain a name for a struct.
- [#2203](https://github.com/vulkano-rs/vulkano/issues/2203): Shader reflection fails to find descriptor set variables if multiple `OpAccessChain` instructions are themselves chained.
- vulkano-shaders: Invalid emitted code for shader input/output interfaces if the shader is missing a name decoration.
- Fixed potential UB when using `MemoryAlloc::try_unwrap`, where the allocation was mapped on contruction of the `MemoryAlloc` but not unmapped on unwrapping, allowing double-mapping.
- Fixed a bug in `GenericMemoryAllocator::allocate`, where the root allocations weren't created with the configured `AllocationType`.
