New data on pion-photoproduction off the proton have been included in the partial-wave analyses Bonn-Gatchina and SAID and in the dynamical coupled-channel approach Julich-Bonn. All reproduce the recent new data well: the double-polarization data for E, G, H, P and T in gamma p -> pi(0)p from ELSA, the beam asymmetry Sigma for gamma p -> pi(0)p and pi(+)n from Jefferson Laboratory, and the precise new differential cross section and beam asymmetry data Sigma for gamma p -> pi(0)p from MAMI. The new fit results for the multipoles are compared with predictions not taking into account the new data. The mutual agreement is improved considerably but still far from being perfect.
