  "message": "Added the \"isosub\" to the cifinput and cifoutput sections, mapping\nit to the \"substrate cut\" (GDS 81:53) layer.  This allows substrate\nregions to extract independently.  Note:  Currently this may require\ncopying the \"isosub\" layer up through the entire hierarchy to the\ntop level for the extraction to work correctly, pending a commit of\nongoing work to enhance the substrate extraction method in magic.\n",
