+* Added the following functions for querying and setting the debug info format and for explicitly building either debug intrinsics (old format) or records (new format). These functions will be deprecated and removed in the future as we move towards removing support for the old debug format. See the `debug info migration guide <https://llvm.org/docs/RemoveDIsDebugInfo.html>`_ for more info.
