I'm trying to reuse some old source code in what is going to be a commercial web application. This old code was made using jQuery 1.2.1, which is dual licensed under the MIT and GPL licenses.
I've seen that recently, jQuery has got rid of the GPL licence and now it's only MIT. I rather not use newer versions since I'd have to test the code again to make sure no bugs were added.
So, Does this change of licence affect old versions of jQuery? I mean, if jQuery 1.12 is MIT only, does that remove GPL from jQuery 1.2.1?
Most importantly, does this put my code under GPL? Do I have to update old jQuery Libraries to prevent my source code from being GPL?
Thanks in advance.
