DirectX Shader Compiler: baixar versions anteriors

## DXC Release Highlights

This release of the DirectX Shader Compiler (DXC) adds production support for Shader Model 6.9,
along with broad correctness, stability, and SPIR-V backend improvements.

For an overview of the Shader Model 6.9 feature set and motivation, see:

- The official DX blog post
- Shader Model 6.9 and the Future of Cooperative Vector blog post

## SPIR-V Backend Improvements

This release includes significant SPIR-V backend updates focused on:

- Improved layout and ABI correctness, including scalar layout rules and structure layout
consistency.
- Expanded type system support, including templates and richer pointer-based types.
- Better code generation correctness for arithmetic, control flow, and resource access.
- Ongoing improvements to debug information emission for SPIR-V targets.

These changes improve interoperability with Vulkan drivers and tooling while aligning behavior more
closely with HLSL and DXIL semantics.

## Compiler Quality and Stability

In addition to new feature support, this release delivers:

- Numerous compiler correctness fixes across HLSL front-end, DXIL, and SPIR-V paths.
- Improved handling of edge cases in constant buffers, resources, and control flow.
- General stability and reliability improvements when compiling complex shaders.

## More Details

This DX compiler release is also available as a NuGet package Microsoft.Direct3D.DXC.

The new DirectX 12 Agility SDK and a hardware driver with appropriate support are required to run
shader model 6.9 shaders. Please see https://aka.ms/directx12agility for details.
