Context. Cluster properties do not seem to be changing significantly during their mature evolution phase; for example, they do not seem to show any strong dynamical evolution at least up to z ~ 0.5, their galaxy red sequence is already in place at least up to z ~ 1.2, and their diffuse light content remains stable up to z ~ 0.8. The question is now to know if cluster properties can evolve more significantly at redshifts that are notably higher than 1.
