We present the three-loop evolution kernel entering the evolution equation of non-singlet leading twist operators. We give an approximate expression for the evolution kernel of non-local operators. We show how to transform the evolution equation from the light-cone representation into the language of local operators. We present the exact anomalous dimension matrix at NNLO for a certain set of local operators, motivated by the conformal expansion of distribution amplitudes.
