New data on pion-photoproduction off the proton have been included in thepartial wave analyses Bonn-Gatchina and SAID and in the dynamicalcoupled-channel approach J\"ulich-Bonn. All reproduce the recent new data well:the double polarization data for E, G, H, P and T in $\gamma p \to \pi^0 p$from ELSA, the beam asymmetry $\Sigma$ for $\gamma p \to \pi^0 p$ and $\pi^+ n$from Jefferson Laboratory, and the precise new differential cross section andbeam asymmetry data $\Sigma$ for $\gamma p \to \pi^0 p$ from MAMI. The new fitresults for the multipoles are compared with predictions not taking intoaccount the new data. The mutual agreement is improved considerably but stillfar from being perfect.
