Thanks for the detailed response.
Can graphics assets be released under the GPL?
If yes, any advice on how to choose between v2 and v3 would be welcome.=

If no, any advice on a suitable license for free use and redistribution=
 would be welcome.

 all versions of XBoard use the same graphics formats. The primary form=
