  I present an update on the electroweak radiative correction factor to
semileptonic tau decays, including a next-to-leading order resummation of large
logarithms. My result differs both qualitatively and quantitatively from the
one recently obtained by Davier et al. As two consequences, (i) the discrepancy
between the predictions for the muon g-2 based on tau decay data and
electron-positron annihilation data increases, and (ii) the g-2 prediction
based on tau decay data appears to be consistent (within about one standard
deviation) with the experimental result from BNL.
