Releases

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.

Release	File	File version	Notes
Windows 10 Creators Update	dxil.dll	10.0.15063.0	no validator version
Windows 10 Creators Update SDK	dxcompiler.dll	10.0.15063.0	!llvm.ident:dxc 1.0
Windows 10 Fall Creators Update	dxil.dll	10.0.16299.15	validator version 1.1
Windows 10 Fall Creators Update SDK	dxcompiler.dll	10.0.16299.15	!llvm.ident:dxc 1.1

All these releases have been via the Windows SDKs or PIX tools. PIX releases have a file version of the form 'dxcoob 0.2017.6.0' and the matching identifier would read '!llvm.ident:dxcoob 2017.06'

The following releases are combining bits from GitHub with the OS-produced dxil.dll. The goal is to provide these milestones every month or two until the next major OS and associated SDK ships.
