We review published rapidity gap results on diffractive W and dijet
production and discuss new results on diffractive b and J/psi production.  The
diffractive structure function of the proton obtained from Roman pot dijet
data is presented and compared with expectations based on the diffractive
parton densities extracted from DIS at HERA.  Also presented are results on
dijet production in double Pomeron exchange.  Finally, we review hard
double-diffractive results (rapidity gaps between jets) and present new
results on soft double diffraction.
