wgpu/CHANGELOG.md

Change Log

Unreleased

• Infrastructure:
  • gfx-hal is replaced by the in-house graphics abstraction wgpu-hal. Backends: Vulkan, Metal, OpenGL ES-3.
• 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.
  • renamed TextureUsage bits: SAMPLED -> TEXTURE_BINDING, STORAGE -> STORAGE_BINDING.
  • renamed InputStepMode to VertexStepMode
  • Implemented Rgb9e5Ufloat format.
• 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.

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
  • Add missing extern "C" in wgpu-core on wgpu_render_pass_execute_bundles
  • Fix incorrect function name wgpu_render_pass_bundle_indexed_indirect to wgpu_render_bundle_draw_indexed_indirect.
