Serena v2 will return the application to the GPL

The maintainers of Serena, an open-source coding agent, announced that starting with v2 the application will return to the GNU General Public License while the underlying SolidLSP language-server library stays MIT. They say Serena began GPL-licensed, moved to MIT after community requests, and that in retrospect that was the wrong call for the application: copyleft keeps distributed derivatives free, while MIT suits a reusable library meant for broad integration. The change is not retroactive, existing MIT releases and commits remain available under MIT, and the repository will document the commit where the application transitions.
