@davide-f @ekatef FYI. I think we can merge this ASAP.
Probably also be good to push another release such that there is a clear difference.
Suggesting v0.3.0 as it is a major change. But I am also fine with other decisions.

[ekatef]

@pz-max a technical question: shouldn't we also re-implement contributions for which we don't have a consent for AGPL?

[pz-max]

@ekatef i think that only applies for WAS addition? (Would be great ti get in this case Emres ok) The other code bits from the non voters are not in the main and replaced by new code as far as I could see

Old code will remain GPL licensed

@pz-max agree, it looks like a definition of WAS shortcut seems to be the only fragment which requires re-licensing. Have written to Emre asking for his consent

Personally, from a code point of view, there are no serious changes with the past v0.2, so, from the code point of view, I don't see the need for a major release.
Moreover v0.2 was released less than a month ago...

To have it as a major release we may have at least the revision of building shapes (PR nearly ready) and the finalization of the country-wise.

However, we don't need to wait for a major release for a new version and we can go for a 0.2.1.

What do you think? Do you want to give high visibility to the license change?

Thanks @ekatef. Emre just gave his ok 👍
Alright @davide-f. I think v0.2.1 is fine as well
Either @ekatef or @davide-f feel free to merge this PR
