Last week I read in the wordpress development blog that wordpress is now GPL. What does this actually mean? I know I can refer to the GNU General Public License page but I just can't seems to understand. So I got a question here: What is the difference between now and before it became GPL? Thank you.
By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program. The GNU General Public License (GNU GPL or simply GPL) is a widely used free software license. Regards.
