Starting with OJS/OMP 3.2, the Public Knowledge Project (PKP) is moving from version 2 to version 3 of the GNU General Public License (GPL) for its software releases. The software license is a legal document that safeguards free and open source software to keep it free and available to the community that builds it. The GPL is one of the most common free software licenses.
