Oolite Bulletins

While reading the "License change redux" thread in the Announcements,
I'd noticed that Oolite 1.6.5 could be considered as dual-licensed, i.e. distributed under either GPL or CC-by-nc-sa-2.

While investigating source code, downloaded from svn as described at the "Running Oolite-Mac" wiki page, I'd found "License.txt" file with states what Oolite is under "Creative Commons
Attribution-NonCommercial-ShareAlike License".
Also, all the source files reference same license.

Which statement is more correct?
(sorry, forum prohibits me to post URLs)

Welcome to the boards. I can't answer your question (although I think the former is correct) - but to let you know you should be able to post urls after your next post or two (it's a limited anti-spam protection measure).

The statement in the License Change Redux thread is correct:

The current official release, 1.65, … may be distributed under its current license … or the GPL.

The 1.65 source code release (there is no 1.6.5) has not been updated because, well, 1.65 has not been updated.
