Every so many versions, or version, AutoCAD/LT, Autodesk changes the file format of the DWG file. They also happen to change the DXF file format at the same time, a point often missed.
The following is a summary description of the many versions and what file formats they create:
AutoCAD/LT2007 and 2008 create R2007 DWG/DXF files.
AutoCAD/LT2004, 2005 and 2006 create R2004 DWG/DXF files.
AutoCAD/LT2000, 2000i and 2002 create R2000 DWG/DXF files.
AutoCAD LT97 and 98 create R14 DWG/DXF files.
AutoCAD LT95 create R13 DWG/DXF files.
AutoCAD LT V1 and V2 create R11/R12 DWG/DXF files.
