# Unreleased (major)

- Added `RuntimePipelineDesc`, an implementation of `PipelineLayoutDesc` that makes creating custom
  layouts easier.
- 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.
- 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.
- Fixed `layers` argument validation in `Swapchain::new_inner`.
- Added `vulkano::pipeline::vertex::BufferlessDefinition` and `BufferlessVertices` to enable
  bufferless drawing.
- Provide 32-bit word constructor for `ShaderModule` (`ShaderModule::from_words`).

# Version 0.6.2 (2017-09-06)

- 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.
