Chiral extrapolations will be essential for many years if one is to connect modern lattice QCD calculations with experiment. Given the enormous efforts made to ensure that the lattice QCD simulations are a rigorous implementation of nonperturbative QCD, it is essential that the chiral extrapolation procedure should also be consistent with all known constraints of QCD. We review the enormous progress made on this problem over the past three or four years.
