Include the version of the producing program in data files
Submitted by Roland Stigge
A Debian user reported the following:
============================================================================ I suggest that the version of the producing program would be included in Dia data files. I could not find such information in the files. And maybe also the producing program in case there will more Dia-compatible software in future.
This would make it easier to locate and fix inconsistencies between different versions of Dia (see bug reports #164291 and #292326, for example). It would also make it possible to support files produced with older versions even when making changes or fixes that are not backwards compatible. At the very least it would enable for a third party to develope a separate converter program that fixes old files for newer Dia versions (to support a smooth transition for users of Debian stable, for example).
