vkd3d/ANNOUNCE

The Wine team is proud to announce that release 1.8 of vkd3d, the Direct3D to
Vulkan translation library, is now available.

This release contains improvements that are listed in the release notes below.
The main highlights are:

  - Support for still many more HLSL features and intrinsics.
  - Performance improvements to vkd3d descriptor updates.
  - Miscellaneous bug fixes.

The source is available from the following location:

The current source can also be pulled directly from the git repository:

  https://gitlab.winehq.org/wine/vkd3d.git

Vkd3d is available thanks to the work of multiple people. See the file AUTHORS
for the complete list.

What's new in vkd3d 1.8
=======================


*** libvkd3d

- Performance improvements have been made to the code that handles descriptor
  updates. In some applications the improvement can be quite significant.

- Host-visible descriptor heaps are persistently mapped on creation. Some
  applications access resource data from the CPU after calling Unmap(), and
  that's supposed to work in practice.

- 1-dimensional texture unordered-access views and shader resource views are
  implemented.

- Shader resource view, unordered access view, and constant buffer view root
  descriptors with NULL GPU addresses are supported.

- Direct3D 12 descriptor heap destruction is delayed until all contained
  resources are destroyed.


*** libvkd3d-shader

- New features for the HLSL source type:
  - Support for the ternary conditional operator "?:".
  - Support for "discard" statements.
  - Support for the "packoffset" keyword.
  - Support for semantics on array types.
  - Support for RWBuffer loads and stores.
  - Register allocation for arrays and structures of resources and samplers
    is implemented.
  - Support for the SV_IsFrontFace pixel shader system-value semantics.
  - Support for using constant expressions as array sizes and indices.
  - Support for dynamic selection of vector components.
  - Support for the following intrinsic functions:
    - D3DCOLORtoUBYTE4()
    - any()
    - asfloat()
    - ddx() and ddy()
    - fmod()
    - log(), log2(), and log10()
    - sign()
    - trunc()
  - The SampleBias(), SampleCmp(), SampleCmpLevelZero(), and SampleGrad()
    texture object methods are implemented.
  - Support for the case-insensitive variants of the "vector" and "matrix"
    data types.
  - Parser support for the "unroll" loop attribute. A warning is output for
    "unroll" without iteration count, and an error is output when an iteration
    count is specified. Actual unrolling is not implemented yet.
  - Parser support for RWStructuredBuffer resources.
  - Parser support for SamplerComparisonState objects. Note that outputting
    compiled effects is not supported yet, but parsing these allows shaders
    containing SamplerComparisonState state objects to be compiled.

- More improvements to HLSL support for the Direct3D shader model 1/2/3
  profiles.

- The section alignment of DXBC blobs produced by
  vkd3d_shader_serialize_dxbc() matches those produced by d3dcompiler more
  closely.

- The "main" function for shaders produced by the SPIR-V target is always
  terminated, even when the source was a TPF shader without explicit "ret"
  instruction.

- Relative addressing of shader input registers is supported by SPIR-V
  targets.
