+------------------------------
+
+* DirectX has been added as an experimental target. Specify
+  ``-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=DirectX`` in your CMake configuration
+  to enable it. The target is not packaged in pre-built binaries.
+* The DirectX backend supports the ``dxil`` architecture which is based on LLVM
