    "abstract": "The present status of soft hadron production in high energy heavy-ion\ncollisions is summarized. In spite of strong evidence for extensive dynamical\nevolution and collective expansion of the fireball before freeze-out I argue\nthat its chemical composition is hardly changed by hadronic final state\ninteractions. The measured hadron yields thus reflect the primordial conditions\nat hadronization. The observed production pattern is consistent with\nstatistical hadronization at the Hagedorn temperature from a state of\nuncorrelated, color deconfined quarks and antiquarks, but requires non-trivial\nchemical evolution of the fireball in a prehadronic (presumably QGP) stage\nbefore hadron formation.",
