We detect evolution in all three correlations between z>0.4 and the present epoch. In particular, in the Omega=0.3, Lambda=0.7 cosmology, the luminosity corresponding to a fixed temperature scales approximately as (1+z)**(1.5+-0.3); the gas mass for a fixed luminosity scales as (1+z)**(-1.8+-0.4); and the gas mass for a fixed temperature scales as (1+z)**(-0.5+-0.4) (all uncertainties are 90% confidence).
