Abstract：
We describe some recent results on isospin breaking corrections which are of relevance for predictions of the leading order hadronic contribution to the muon
anomalous magnetic moment a_μ^hadLO when using τ lepton data. When these corrections are applied to the new combined data on the π^±π⁰ spectral function, the prediction for a_μ^hadLO based on τ lepton data gets closer to the one obtained using e⁺e^－ data.
