# Unreleased
<!--
    Please add new changes at the bottom, preceded by a hyphen -.
    Breaking changes should be listed first, before other changes, and should be preceded by - **Breaking**.
-->

- **Breaking** Vulkano-shaders now checks if the device supports the shader's SPIR-V version, when loading the shader.
- **Breaking** (but unlikely) Vulkano-shaders now compiles to SPIR-V 1.0 by default. If your shader needs features only available in a higher version, you can specify the target version on the `shader!` macro with the new `vulkan_version: "major.minor"` and `spirv_version: "major.minor"` arguments.
- Added `DeviceExtensions::khr_spirv_1_4`, which allows SPIR-V 1.4 shaders in Vulkan 1.1.
- Added `FunctionPointers::api_version` to query the highest supported instance version.
- Added `Instance::api_version` and `Device::api_version` to return the actual supported Vulkan version. These may differ between instance and device, and be lower than what `FunctionPointers::api_version` and `PhysicalDevice::api_version` return (currently never higher than 1.1, but this may change in the future).
- Fixed the issue when creating a buffer with exportable fd on Linux(see to #1545).
- **Breaking**, change to `ImageFormatProperties::sample_counts` field.
  - `sample_counts` field is originaly represented as u32 type, which is now represented by `SampleCounts` struct-type which is a boolean collection of supported `sample_counts`.
  - Added conversion function between SampleCountFlagBits (u32-type) and `SampleCounts` type.

# Version 0.23.0 (2021-04-10)

- **Breaking** Changes to command buffers:
  - `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 creating, and some of its methods are only implemented for builders that create `PrimaryAutoCommandBuffer`.
  - The `Flags` enum is renamed to `CommandBufferUsage`, and is exported from the main `command_buffer` module. The `None` variant is renamed to `MultipleSubmit`.
  - Simplified the number of constructors on `AutoCommandBufferBuilder` by adding a `CommandBufferUsage` parameter.
  - `Kind` has been renamed to `CommandBufferLevel`, and for secondary command buffers it now contains a single `CommandBufferInheritance` value.
  - `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`.
    - Renamed: `AttachmentDescription` > `AttachmentDesc`, `PassDescription` > `SubpassDesc`, `PassDependencyDescription` > `SubpassDependencyDesc`.
    - `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.
- Support for queries:
  - **Breaking** `UnsafeQueryPool`, `UnsafeQuery` and `UnsafeQueriesRange` have `Unsafe` removed from their names.
  - **Breaking** `QueriesRange` is now represented with a standard Rust `Range` in its API.
  - **Breaking** The secondary command buffer constructors that have parameters for queries will check if the corresponding features are enabled, and return a different error type.
  - Removed `OcclusionQueriesPool`, which was incomplete and never did anything useful.
  - `get_results` has been added to `QueriesRange`, to copy query results to the CPU.
  - The following functions have been added to both `SyncCommandBufferBuilder` and `AutoCommandBufferBuilder`: `begin_query` (still unsafe), `end_query` (safe), `write_timestamp` (still unsafe), `copy_query_pool_results` (safe), `reset_command_pool` (still unsafe).
  - Better documentation of everything in the `query` module.
  - An example demonstrating occlusion queries.
- **Breaking** Improved the handling of image aspects a little, with the enum `ImageAspect` and the struct `ImageAspects`. `UnsafeCommandBufferBuilderImageAspect` has been removed.
- **Breaking** Removed the separate structs for each image format. Now, only the `Format` enum exists.
  - Traits that no longer make sense in this context have been removed: `FormatDesc`, the `Possible*FormatDesc` traits, `StrongStorage`.
  - In types that had a type parameter for the format type, it has been removed.
  - `AcceptsPixels` has been converted to `Pixel`, which is implemented on the pixel type rather than on the format type.
- **Breaking** `shader!` will generate descriptor information for all variables declared in the shader module, even if they are not used. *This reverts the default behavior from the last release.*
  - **Breaking** Added the `exact_entrypoint_interface` option to `shader!` to force vulkano to only generate descriptor information for variables that are used. (the default behavior from the last release)
- **Breaking** `AccessFlagBits` is renamed to `AccessFlags`.
- **Breaking** Minor refactor of `UnsafeBuffer`:
  - Replaced the various usage functions with a single `usage` function, mirroring the change made earlier to `UnsafeImage`.
  - The `SparseLevel::sparse` member is removed, and `UnsafeBuffer::new` takes `Option<SparseLevel>` instead.
- **Breaking** `Swapchain` is now constructed using a builder. `Swapchain::start` will start building a new blank swapchain. Calling `recreate` on an existing swapchain will create a builder filled with all the properties of the old swapchain.
- Added two methods to `Format`: `planes` to query the number of planes in the format, and `aspects` to query what aspects an image of this type has.
- The deprecated `cause` trait function on Vulkano error types is replaced with `source`.
- Fixed bug in descriptor array layers check when the image is a cubemap.
- 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.
- Vulkano-shaders: Added support for StoragePushConstant8 SPIR-V capability.
- Fixed a bug which caused a segfault when extending memory allocation info in DeviceMemoryBuilder
- `BufferlessDefinition` and `BufferlessVertices` now derive `Copy` and `Clone`. This allows `GraphicsPipelineBuilder`s that have not yet defined a vertex buffer type to be cloned.
- Various functions for converting to/from Vulkan flags have been consolidated into implementations of the standard `From` trait.
- Export root-level `entry_point` method on `loader::FunctionPointers` type.
- Add few more `InstanceExtensions` from KHR and EXT.

# Version 0.22.0 (2021-03-31)

- **Breaking** Updated all code to Rust 2018 edition.
- **Breaking** DeviceMemoryBuilder::new() takes in `memory_index` rather than `MemoryType`.
- 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`.
- Fixed missing barriers in dispatch calls
  - **Breaking** `shader!` no longer marks descriptor sets as readonly as a fallback when it doesn't know
    - **Breaking** The keyword `readonly` might need to be added in front of the `buffer` keyword in GLSL files to get them working again
- **Breaking** Changes to image types:
  - 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
- Replaced deprecated `compare_and_swap` with `compare_exchange`.
- `UnsafeCommandPoolAlloc` now implements `DeviceOwned`.
- Allow `const` usage of features and `BufferUsage`.
- Opaque fd and dma-buf import support on `Linux`.
- `DeviceMemoryMapping` to separate device memory and mappings.
- Added external memory support for `DeviceLocalBuffer` for Linux.
- Implemented synchronization for `SyncCommandBufferBuilder::execute_commands`.
- `AutoCommandBufferBuilder::execute_commands` is now fully safe to use.
- `SyncCommandBufferBuilder` now becomes poisoned when it returns an error, to prevent using the builder in an inconsistent state.
- Added a `dispatch_indirect` command to `AutoCommandBufferBuilder`.

# Version 0.21.0 (2021-03-05)

- **Breaking** `Message::layer_prefix` turned to Option to prevent segfaults when Vulkan message didn't provide `pMessageIdName` value
- **Breaking** On `AutoCommandBufferBuilder`, methods that bind a descriptor set now take a `dynamic_offsets` parameter
- **Breaking** On `AutoCommandBufferBuilder` and `SyncCommandBufferBuilder`, the `update_buffer` method now takes `data` by reference

- Added support for `ImageAspect` and YV12/NV12 formats,  for use with the UnsafeImage API.
- Added basic VK_KHR_external_memory, VK_KHR_external_memory_fd, and VK_EXT_external_memory_dma_buf support.
- Fixed potential segmentation fault in `ComputePipeline` when referencing `PipelineCache` objects.

- Updated dependencies:
  - `crossbeam` 0.7 -> 0.8
  - `half` 1.6 -> 1.7
  - `shaderc` 0.6 -> 0.7
  - `smallvec` 1.4 -> 1.6

- Added `DeviceExtensions::required_extensions` function that returns a set of available extensions required to create `Device` on this platform.
- `FormatFeatures` now implements `Copy`.
- Removed the `AttachmentImageView` trait, which didn't appear to be used for anything anyway.

# Version 0.20.0 (2020-12-26)

- **Breaking** The `ImmutableImage::from_iter` and `ImmutableImage::from_buffer` can build Mipmaps
- **Breaking** `CpuAccessibleBuffer` now uses `RwLock` from `parking_lot`.
- **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`.
- **Breaking** Update dependency `winit` 0.22 -> 0.24
- **Breaking** Added an Option to the ComputePipeline constructor to enable pipeline caching.
- Add support for 8bit storage.
- 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`.
- Added a `properties` method to `Format`.
- Added additional device feature flags for enabling SPIR-V related capabilities.
- Added method `copy_buffer_dimensions` that allows copying parts of buffers containing arrays.
- Added `debug_marker_begin`, `debug_marker_end` and `debug_marker_insert` to `AutoCommandBufferBuilder`.
- Fixed surface creation function on Windows(PR #1410).
- Travis CI Linux Nightly job temporary disabled until #1423 resolved.

- Added method `build_with_cache` to the `GraphicsPipelineBuilder` that enables pipeline caching.
- Check usage bits on image when creating image view.
- 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.
- Added support for including precompiled shaders in vulkano-shaders using the `bytes` option.
- Added an option for Vulkano-Shaders macro to automatically generate standard
  traits(Default, PartialEq, etc) implementations for Rust types generated from
  the Shader types, and to derive these structs with external traits.
- 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`.

# Version 0.19.0 (2020-06-01)

- **Breaking** AutoCommandBufferBuilder methods now take a mutable reference to `self` instead of taking ownership
- Update `smallvec` 1.2 -> 1.4

- Added additional checks around image/device compatibility.
- Fixed all warnings as of Rust 1.43.1
- 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, ...}`.
- Allow applications to access the instance and device pointers
- Add a helper function '.boxed()' on the `GpuFuture` that is short for `Box::new(yourFuture) as Box<dyn GpuFuture>`
