 Changes to the Debug Info
 ---------------------------------
 
+* LLVM has switched from using debug intrinsics internally to using debug
+  records. This should happen transparently when using the DIBuilder to
+  construct debug variable information, but will require changes for any code
+  that interacts with debug intrinsics directly; for more information, see the
+  `migration docs <https://llvm.org/docs/RemoveDIsDebugInfo.html>`_.

Do we need to mention that testing for debug intrinsics will be best-effort going forward (/soon)?
