Unreleased (major)

Use dynamically loaded libvulkan like on other platforms instead of linking to MoltenVK on macOS
Updated winit to version 0.17.
Allow custom implementations of RenderPassDesc to specify VK_SUBPASS_EXTERNAL as a dependency source or destination
Added vulkano_win::create_vk_surface which allows creating a surface safely without taking ownership of the window.
AutoCommandBufferBuilder::draw and friends no longer consume the DynamicState argument, allowing reuse between calls.

Version 0.9.0 (2018-03-13)

Changed ShaderInterfaceMismatchError to be more verbose.
Allow depth/stencil images to be used with AutoCommandBufferBuilder::copy_image_to_buffer()
Allow Surface to own the window it references.
Clear value validation for AutoCommandBufferBuilder::begin_render_pass()
Fix occasional truncation of glslang_validator when glsl-to-spirv is rebuilt
Fix linking against MoltenVK >= 0.19.0
Fix panic on DeviceLost error after resizing swapchain on nvidia/amd hardware
Added AutoCommandBufferBuilder::copy_image
Added VulkanObject::TYPE to look up the DebugReportObjectTypeEXT of an object
Added Device::set_object_name and Device::set_object_name_raw
Added GraphicsPipelineBuilder::with_auto_layout to simplify use of dynamic buffers.

Yanked

Allow impl_vertex! to support generic structs.
Added GraphicsPipelineBuilder::with_pipeline_layout.
Fixed creating a buffer view not checking the min_texel_buffer_offset_alignment limit.
Added support for loading the VK_EXT_debug_marker extension and adding debug markers to UnsafeCommandBufferBuilder
Changed GraphicsPipelineBuilder to default to a buffer-less vertex input.
Deprecated pipeline::input_assembly::InputAssembly.

Fixed an HiDPI scaling issue on MacOS in vulkano-win.
Fixed le() and ge() for DescriptorsCount, which also fixes a potential memory leak when allocating descriptor sets.
Fixed the ordered_passes_renderpass! macro not working properly when using resolve.
Added an optional resolve entry in pass for single_pass_renderpass!, for resolving multisampled attachments into non-multisampled attachments.
Fixed the value of rasterizationSamples not corresponding to the render pass.
Added GraphicsPipelineBuilder::sample_shading_disabled, sample_shading_enabled, alpha_to_coverage_disabled, alpha_to_coverage_enabled, alpha_to_one_disabled and alpha_to_one_enabled. Added GraphicsPipelineCreationError::SampleRateShadingFeatureNotEnabled and AlphaToOneFeatureNotEnabled.
Deprecated pipeline::multisample::Multisample.

Added RuntimePipelineDesc, an implementation of PipelineLayoutDesc that makes creating custom layouts easier.
Changed CpuBufferPool::next() and chunk() to return a Result in case of an error when allocating or mapping memory.
Changed CommandBufferExecError::AccessError to provide a hint of where the error occurs.
Added vulkano::pipeline::vertex::BufferlessDefinition and BufferlessVertices to enable bufferless drawing.
Changed ImageAccess::try_gpu_lock and unlock() to verify whether the image layout is correct, especially at the first usage of an image.
Changed BufferAccess::conflict_* and ImageAccess::conflict_* to forbid querying a specific range of the resource.
Fixed layers argument validation in Swapchain::new_inner.
Added a 32-bit word constructor for ShaderModule (ShaderModule::from_words).
Changed the various is_superset_of functions to return a Result instead of a bool.

Added checking compatibility between the descriptor sets and the pipeline object when adding a draw or compute command.
Fixed several bugs in the validation checks of blit_image.
Fixed blit_image, copy_buffer_to_image and copy_image_to_buffer not taking the mipmap level into account when checking for the correct image dimensions.
Added ImageDimensions::mipmap_dimensions() and ImageDimensions::num_mipmaps().
Added an implementation of DeviceOwned for QueuesIter and Queue.
Fixed the standard command pool and descriptor pool being destroyed too often.
Added #[allow(non_snake_case)] to structs generated by vulkano-shaders.
