Thank you for your work to help people read DWG files! I'm a volunteer contributor to Wikidata, and I'd like to know if you support importing all versions of DWG files. On this Wikidata item, there is a list of versions 1.0 up through version 2013-2014. I'd like to create specific statements on the Wikidata item for LibreCAD in Wikidata to indicate each of the versions of DWG files LibreCAD can read. Would you be willing to point me to any such documentation, so that I could cite it in the references in Wikidata?

DWG support in LibreCAD is supported by the library libdxfrw that is included in LibreCAD sources.
If you look in the LibreCAD sources for the file drw_base.h you can see all the supported versions.

Here is an excerpt:

enum Version {
    AC1006,       /*!< R10. */
    AC1009,       /*!< R11 & R12. */
    AC1012,       /*!< R13. */
    AC1014,       /*!< R14. */
    AC1015,       /*!< ACAD 2000. */
    AC1018,       /*!< ACAD 2004. */
    AC1021,       /*!< ACAD 2007. */
    AC1024,       /*!< ACAD 2010. */
    AC1027        /*!< ACAD 2013. */
