Change Log

TBD

  • All:
    • expose more formats via adapter-specific feature
    • fix creation of depth+stencil views
  • Metal:
    • fix usage of work group memory

v0.10 (2021-08-18)

  • Infrastructure:
    • gfx-hal is replaced by the in-house graphics abstraction wgpu-hal. Backends: Vulkan, Metal, D3D-12, and OpenGL ES-3.
    • examples are tested automatically for image snapshots.
  • API:
    • cross feature is removed entirely. Only Rust code from now on.
    • processing SPIR-V inputs for later translation now requires spirv compile feature enabled
    • new Features::SPIRV_SHADER_PASSTHROUGH run-time feature allows providing pass-through SPIR-V (orthogonal to the compile feature)
    • several bitflag names are renamed to plural: TextureUsage, BufferUsage, ColorWrite.
    • the SwapChain is merged into Surface. Returned frames are Texture instead of TextureView.
    • renamed TextureUsage bits: SAMPLED -> TEXTURE_BINDING, STORAGE -> STORAGE_BINDING.
    • renamed InputStepMode to VertexStepMode.
    • readable storage textures are no longer a part of the base API. Only exposed via format-specific features, non-portably.
    • implemented Rgb9e5Ufloat format.
    • added limits for binding sizes, vertex data, per-stage bindings, and others.
    • reworked downlevel flags, added downlevel limits.
    • resolver = "2" is now required in top-level cargo manifests
  • Fixed:
    • Device::create_query_set would return an error when creating exactly QUERY_SET_MAX_QUERIES (8192) queries. Now it only returns an error when trying to create more than QUERY_SET_MAX_QUERIES queries.

wgpu-core-0.9.2

  • fix Features::TEXTURE_SPECIFIC_FORMAT_FEATURES not being supported for rendertargets

v0.9 (2021-06-18)

  • Updated:
    • naga to v0.5.
  • Added:
    • Features::VERTEX_WRITABLE_STORAGE.
    • Features::CLEAR_COMMANDS which allows you to use cmd_buf.clear_texture and cmd_buf.clear_buffer.
  • Changed:
    • Updated default storage buffer/image limit to 8 from 4.
  • Fixed:
    • Buffer::get_mapped_range can now have a range of zero.
    • Fixed output spirv requiring the "kernal" capability.
    • Fixed segfault due to improper drop order.
    • Fixed incorrect dynamic stencil reference for Replace ops.
    • Fixed tracking of temporary resources.
    • Stopped unconditionally adding cubemap flags when the backend doesn't support cubemaps.
  • Validation:
    • Ensure that if resources are viewed from the vertex stage, they are read only unless Features::VERTEX_WRITABLE_STORAGE is true.
    • Ensure storage class (i.e. storage vs uniform) is consistent between the shader and the pipeline layout.
    • Error when a color texture is used as a depth/stencil texture.
    • Check that pipeline output formats are logical
    • Added shader label to log messages if validation fails.
  • Tracing:
    • Make renderpasses show up in the trace before they are run.
  • Docs:
    • Fix typo in PowerPreference::LowPower description.
  • Player:
    • Automatically start and stop RenderDoc captures.
  • Examples:
    • Handle winit's unconditional exception.
  • Internal:
    • Merged wgpu-rs and wgpu back into a single repository.
    • The tracker was split into two different stateful/stateless trackers to reduce overhead.
    • Added code coverage testing
    • CI can now test on lavapipe
