Update of g-2 of the muon and △α

摘要：

We update our Standard Model predictions for g-2 of the muon and for the hadronic contributions to the running of the QED coupling,△α(5)had(M2Z).Particular emphasis is put on recent changes in the hadronic contributions from new data in the 2π channel and from the energy region just below 2 GeV.
