Change Log

v0.6 (2021-08-18)

• development release for wgpu-0.10
• API:
  • atomic types and functions
  • storage access is moved from global variables to the storage class and storage texture type
  • new built-ins: primitive_index and num_workgroups
  • support for multi-sampled depth images
• WGSL:
  • select() order of true/false is swapped
• HLSL backend is vastly improved and now usable
• GLSL frontend is heavily reworked

v0.5 (2021-06-18)

• development release for wgpu-0.9
• API:
  • barriers
  • dynamic indexing of matrices and arrays is only allowed on variables
  • validator now accepts a list of IR capabilities to allow
  • improved documentation
