Today the Free Software Foundation (FSF) is releasing the first major update to the GPL license (General Public License) at a meeting in Boston. FSF.org will stream the announcement on their website today (starting around noon EDT).
So why should you upgrade your license to Version 3? It’s actually not a simple answer, and you don’t have to upgrade to the new version if you don’t want to. The FSF is offering a ‘Why Upgrade’ article on their site, explaining why they feel you should.
If you prefer to decide on your own, instead of being told why you should upgrade, you might want to read through the Frequently Asked Questions about GPLv3.
I don’t think the GPLv3 is as good a license as v2
you know that people are going to stop and read it more carefully. You might want to do the same and decide for yourself.
