We summarize recently completed studies of the equation of state for Q
CD with two flavors of Kogut-Susskind quarks on lattices with six time
slices, and of the high temperature crossover for two flavors of Wils
on quarks with a Symanzik improved gauge action and the clover quark a
ction. In addition, we give a progress report on extensions of the Kog
ut-Susskind calculations at N-t = 4 to smaller masses in an effort to
clarify the scaling behavior near the transition.
