/ Abstract
Abstract We conclude our analysis of the Nt = 6 equation of state (EOS) for two flavor QCD, first described at last year's conference. We have obtained new runs at amq = 0.025 and improved runs and amq = 0.0125. The results are extrapolated to mq = 0, and we extract the speed of sound as well. We also present evidence for a restoration of the SU(2)×SU(2) chiral symmetry just above the crossover, but not of the axial U(1) chiral symmetry.
