Following updates in the compilation of e^+ e^- –> hadrons data, I will talk about re-evaluations of the hadronic vacuum polarization contributions to the anomalous magnetic moment of the muon (a_¥mu). Combining the results for the hadronic vacuum polarization contributions with recent updates for the hadronic light-by-light corrections, the electromagnetic and the weak contributions, the deviation between the measured value of a_¥mu and its Standard Model prediction amounts to ¥Delta a_¥mu = (28.02 +/- 7.37) x 10^{-10}, corresponding to a muon g-2 discrepancy of 3.8 ¥sigma.
