  I present a status report of the hadronic vacuum polarization effects for the
muon $g-2$, to be considered as an update of [1]. The update concerns recent
new inclusive $R$ measurements from KEDR in the energy range 1.84 to 3.72 GeV.
For the leading order contributions I find $a_\mu^{\mathrm{had}(1)}=(688.07\pm
4.14)[688.77\pm3.38]\times 10^{-10}$ based on $e^+e^-$data [incl. $\tau$ data],
$a_\mu^{\mathrm{had}(2)}= (-9.93\pm 0.07) \times 10^{-10}$ (NLO) and
$a_\mu^{\mathrm{had}(3)}= (1.22\pm 0.01) \times 10^{-10}$ (NNLO). Collecting
recent progress in the hadronic light-by-light scattering I adopt
$\pi^0,\eta,\eta'$ [$95 \pm 12$] + axial--vector [$8 \pm ~3$] + scalar [$-6\pm
~1$] + $\pi,K$ loops [$-20\pm 5$] + quark loops [$22\pm ~4$] + tensor [$1\pm
~0$] + NLO [$3\pm ~2$] which yields $
a^{(6)}_\mu(\mathrm{lbl},\mathrm{had})=(103 \pm 29) \times 10^{-11}.$ With
these updates I find $a_\mu^{\rm exp}-a_\mu^{\rm the}=(31.3\pm 7.7)\times
10^{-10}$ a 4.1 $\sigma$ deviation. Recent lattice QCD results and future
prospects to improve hadronic contributions are discussed.
