With a quick glance at the KTooN codebase, I made the following observation:

 

The KTooN commits from 2010-05-15 11:48 and 11:49 with message "Updating license version from source code -> GPL 3" changed the license from "GPL v2 or any later version" to "GPL v3 or any later version".

 

(Please correct me if I am wrong, the commits change about 1000 lines and I did not check every change!)

 

From my POV you have two options. Both include first asking _every_ commiter following up the license change commits in a documented way if they allow changing the license to "GPL v2 or any later version". After you received their approvals you can:

 

Either

* revert the two license change commits

* do a rebase of all following commits

* change newly introduced licenses

 

Or

* revert the license change commits and perform relicensing at once.

 

I see no need to contact Monica about that issue, since all approvals that are necessary for doing the relicensing are from individual commiters (who commited after the relicense in 2010, as far as I understood).

 

Greetings,

Andreas


Hello there,

It seems you are right, yesterday I was talking to a friend who has a wide knowledge of the GPL licenses and he told me
the same. I just need the approval from all the developers who made contributions between the moment I changed the license
of Tupi from GPL v2 to v3 and the present.

If you take a look at the old KTooN repository, you will find out that the only user who made commits to the project from 2010,
even before the change of license, was me (xtingray):

http://svn.berlios.de/viewvc/ktoon/

About the repository of Tupi, you will be able to confirm that only Cristian Cepeda (he helped me to fix some .pro files
to make possible the compilation of Tupi in OSX) and me were working on the code:

https://github.com/xtingray/tupi/commits/master?page=20

About Cristian, I already contacted him and this was his answer:

Hello Gustavo,

About the Tupi relicensing.

I absolutely agree with the change of license, even more when it will help to spread the word about your project and to make it part of something so great as the KDE project. I have no objections. Do it!

So, now I'm definitely convinced that the change of license is absolutely legal. The logs of the repositories should
work as evidence, right?

I'll appreciate all your feedback about this matter.
Thank you!

PS: In case, someone believes that I made the change of the license of KTooN from GPL v2 to v3 without asking to Monica
Ortiz (Toonka Films CEO in that time), here I found the "official account" of KTooN at Twitter. I created it at the time I was
working with Monica and I wrote every one of the tweets that you'll find here:

https://twitter.com/ktoon_net

The one I want to hightlight is this:

https://twitter.com/ktoon_net/status/14052613828

Why? Because all that I posted from that account was under the supervision/approval of Monica.
