Supported by a strong community (the Free Software Foundation - FSF). Copy, modification and distribution authorised. Changes/dates must be traced in source files. Any derivative must also be made available under one or more of these GPL versions. GPL-2.0-or-later Compatibility / interoperability are known sources of tension when a project combines the covered code with non-GPL sources from other stakeholders, because according to the FSF linking other software to GPLed works extends the GPL coverage to these other programs. Licensing under ‘GPL-2.0 or later’ may be recommended since it is compatible with all GPL versions (2 and 3). At the contrary, licensing under ‘GPL-2.0-only’ is not compatible with GPL-3.0.
