Improved predictions for of the muon and

Abstract: We update the Standard Model predictions of the anomalous magnetic moment of the muon, , and the value of the QED coupling at the Z-boson mass, incorporating the new data obtained by CMD-2 and KLOE, as well as the corrected SND data, and other improvements. The prediction for is about lower than before, and has a smaller uncertainty, which corresponds to a 3.4σ deviation from the measured value. The prediction for the QED coupling is .
