  I review recent lattice QCD results on a few selected topics which are
relevant to the heavy ion physics community. Special emphasis is put on the QCD
equation of state at vanishing and nonzero baryon chemical potential, the onset
of deconfinement of open strange and charmed hadrons, the contribution from
experimentally not yet observed hadrons to the thermodynamics of the hadronic
gas and their influence on freeze-out conditions of strange and light-quark
hadrons.
