- **Breaking** `AutoCommandBuffer` and the `CommandBuffer` trait have been split in two, one for primary and the other for secondary command buffers. `AutoCommandBufferBuilder` remains one type, but has a type parameter for the level of command buffer it will be create, and some of its methods are only implemented for builders that create `PrimaryAutoCommandBuffer`.
- **Breaking** `Kind` has been renamed to `CommandBufferLevel`, and for secondary command buffers it now contains a single `CommandBufferInheritance` value.
- **Breaking** `CommandBufferInheritance::occlusion_query` and `UnsafeCommandBufferBuilder::begin_query` now take `QueryControlFlags` instead of a boolean.
- **Breaking** The non-default constructors of `ImageView` have been replaced with a builder, created with `ImageView::start(image)`.
- **Breaking** Added support for component mapping/swizzling on image views.
-`image::Swizzle` is moved and renamed to `image::view::ComponentMapping`. It now has an `is_identity` method.
- A non-default component mapping can now be specified for image views, via the new builder. A `ComponentMapping` parameter has been added to `UnsafeImageView` as well.
- The `identity_swizzle` method on the `ImageViewAbstract` trait has been replaced with `component_mapping`, which returns a `ComponentMapping` directly.
- Storage image and input attachment descriptors now check for identity swizzling when being built.
- **Breaking** Major rearranging of framebuffer and render pass-related types:
- The `framebuffer` module is renamed to `render_pass`.
-`RenderPassDesc` is now a struct, not a trait. The methods have been simplified, returning a slice reference to the `attachments`, `subpasses` and `dependencies`.
-`EmptySinglePassRenderPassDesc` is replaced with the `RenderPassDesc::empty` constructor, or its `Default` implementation.
- The `RenderPassCompatible`, `RenderPassDescClearValues` and `RenderPassSubpassInterface` traits are removed, their functionality is moved to `RenderPassDesc`.
-`RenderPass` takes a concrete `RenderPassDesc` value for construction, and no longer has a type parameter.
- The `RenderPassAbstract` trait is removed.
-`GraphicsPipeline` and `Framebuffer` no longer have a render pass type parameter.
-`GraphicsPipelineAbstract` and `FramebufferAbstract` have trait methods to retrieve the render pass instead.
- The `ordered_passes_renderpass!` and `single_pass_renderpass!` macros are unchanged externally.
- Vulkano-shaders: Fixed and refined the generation of the `readonly` descriptor attribute. It should now correctly mark uniforms and sampled images as read-only, but storage buffers and images only if explicitly marked as `readonly` in the shader.
- Fixed `shader!` generated descriptor set layouts for shader modules with multiple entrypoints.
- **Breaking** Prefixed `shader!` generated descriptor set `Layout` structs with the name of the entrypoint the layout belongs to. For shaders generated from GLSL source, this means `Layout` has been renamed to `MainLayout`.
- **Breaking** `shader!` will no longer generate descriptor information for variables that are declared but not used in a shader.
- **Breaking** `shader!` now accepts structs in shader interfaces decorated with `BufferBlock` rather than `Block`.
- Image types no longer implement `ImageViewAccess`.
-`Dimensions` is removed. Image constructors now take `ImageDimensions`.
-`ImageDimensions` no longer has the `cubemap_compatible` member. Instead, several image constructors take `ImageCreateFlags` which specifies this aspect.
- Replaced the various functions of `UnsafeImage` to query format features and usage with two that simply return `Formatfeatures` and `ImageUsage`.
- **Breaking** Changes to image view handling:
- Created a new `image::view` module for all image view related things.
- Introduced a new `ImageView` type, a safe wrapper around `UnsafeImageView`.
- The `ImageViewAccess` trait is renamed to `ImageViewAbstract`, some methods added, removed or renamed. `ImageView` implements this trait.
-`UnsafeImageView` no longer holds image usage information, nor does it check for valid usage.
- **Breaking** `UnsafeCommandBuffer` and `SyncCommandBuffer` and their corresponding builders and other related types no longer have a type parameter for the command pool allocation, and no longer keep the command pool alive. Their constructors now take an `&UnsafeCommandPoolAlloc`. Users must now ensure that the pool allocation outlives the command buffers and their builders (`AutoCommandBuffer` does this itself).
- **Breaking** The `CommandBuffer` trait no longer has the `PoolAlloc` associated type, and has four new methods: `num_buffers`, `buffer`, `num_images` and `image`.
- **Breaking** structures passed to `ImmutableBuffer::from_data` and `CpuAccessibleBuffer::from_data` must implement [`Copy`](https://doc.rust-lang.org/std/marker/trait.Copy.html) to ensure soundness of these functions
- **Breaking** The `Kind` and `SubpassContents` types have been moved to the root of the `command_buffer` module.
- **Breaking** On `AutoCommandBufferBuilder`, the methods `begin_render_pass` and `next_subpass` now take `SubpassContents` instead of a boolean value.
- **Breaking** The `CommandBuffer` trait now has an additional required method, `kind`.
- Some safety checks have been added to `execute_commands`/`execute_commands_from_vec` on `AutoCommandBufferBuilder`, but not everything is checked yet so it's still unsafe to call.
- Added two vulkano-win features `raw-window-handle_` and `winit_` to be able to use vulkano without winit.
- Added function to create surface from `RawWindowHandle`.
- Fixing an assertion panic in the SyncCommandBuffer. If the buffer encountered an error while locking the necessary resources, it would unlock all previously locked resources. Images were unlocked incorrectly and an assert in the image unlock function would panic.
- Fixed clear `Cubemap` and `CubemapArray` framebuffer attachment dimensions; previously only 1/6th of the layers in each of these image layouts were actually considered by the framebuffer (for clearing and rendering). This seems to have been a result of the difference between `Dimensions` and `ImageDimensions`.
- Provides new API to fetch additional information of the Physical Device from the `PhysicalDeviceProperties2KHR` structure whenever it possible. In the current implementation only `subgroupSize` property is fetching. This interface can be extended in the future to obtain more metadata depending on community needs.
-`dynamic-local-size` compute shader example added showing how to utilize `subgroupSize` to compute and set shader's local size in run time.
- Fixed Vulkano Shaders bug when compute shader local group layout values bound to specialization constants. Now it is possible to define the layout in form of `layout(local_size_x_id = 12, local_size_y_id = 13, local_size_z = 1) in;` and then set the values as `SpecializationConstants {constant_12: 8, constant_13: 4, ...}`.
- **Breaking** Added `fullscreen_exclusive` field to `Swapchain` initializers to allow the user to specify how fullscreen exclusivity should be handled.
+ Swapchain methods added: `Swapchain::acquire_fullscreen_exclusive()`, `Swapchain::release_fullscreen_exclusive()`, and `Swapchain::is_fullscreen_exclusive()`
- Update shaderc to 0.6. This again allows to use locally installed libraries which reduces the build-time significantly on Arch/Voidlinux (see https://github.com/google/shaderc-rs/issues/58)
- Compressed texture formats can now be uploaded using `ImmutableImage::from_iter`, `ImmutableImage::from_buffer`, `AutoCommandBuilder::copy_buffer_to_image_dimensions`,
This is an emergency breaking breaking change. It fixes Undefined Behaviour that was preventing the compilation of Vulkano on the latest rust nightlies.
- Update shaderc to 0.5. New shaderc has improved pre-built options for libshaderc that significantly reduce package build time and are appropriate for use in CI
-`QueueFamily::explicitly_supports_tranfers` only returns true if `vk::QUEUE_TRANSFER_BIT` is set instead of also always returning true. Removed `supports_transfers`.
