I pay particular attention to studies of the equation of state and the light they throw on conformal symmetry and the large N_c limit, and to the structure of the phase diagram for N_f=2+1.Plenary talk at Quark Matter 2008, Jaipur, India (8 pages, 5 figures)Nuclear TheoryHigh Energy Physics - LatticeHigh Energy Physics - PhenomenologyNuclear ExperimentPhases and properties of quark mattertext
