No it’s the opposite. Specifically, from Section 14 of GPLv3: If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. In Guix we encode this as ‘gpl3+’. So the rule is: always put ‘+’ unless the source code headers or some other prominent file restricts to a specific version of the license. Ludo’.
