The following table provides important information about released versions of the compiler components. The compiler releases as dxcompiler.dll, and can be recognized by the !llvm.ident value produced in DXIL modules. The validator releases as dxil.dll, and can be identified by a runtime query; the rules applies can be identified via DXIL metadata.

The latest release including the dxcompiler.dll library, the dxc.exe executable, and the dxil.dll validator library can be downloaded from the GitHub project releases tab.
