PUN Classic (v1), PUN 2 and Bolt are in maintenance mode. We will support Unity 2022 with PUN 2, but no new features will be added. Of course all your PUN & Bolt projects will continue to work and run with the known performance in the future. For any upcoming or new projects: please switch to Photon Fusion or Quantum.
