License clarification

[throwaway1037]

Is the project licensed under GNU-GPL2-only or GNU-GPL2-or-later?

If the former, please may it be released under the latter?

Thank you very much.

It's GPL2-only, changing it would be quite an effort, because all contributors would have to agree.

[throwaway1037]

Please may we get the ball rolling on upgrading, even if it takes a while? I'd love to fork the project but GPL2-only, whilst a strong license, is relatively weak and vulnerable compared to GPL2-or-later.

[noughtmare]

Actually, I might be wrong. There is some more information on this issue: yi-editor/yi-rope#10.

[throwaway1037]

Would I be correct in stating that the project is actually GPL2-or-later due to what the package metadata implied?

[throwaway1037]

Otherwise these appear to all be authors with the command git shortlog -s | cut -c8-:
(Someone appears to be named the empty string.)
