Following updates in the compilation of $e^+e^-\rightarrow{\rm hadrons}$ data, this work presents re-evaluations of the hadronic vacuum polarisation contributions to the anomalous magnetic moment of the electron ($a_e$), muon ($a_\mu$) and tau lepton ($a_\tau$), to the ground-state hyperfine splitting of muonium and also updates the hadronic contributions to the running of the QED coupling at the mass scale of the $Z$ boson, $\alpha(M_Z^2)$. Combining the results for the hadronic vacuum…

This article reviews the status of lattice calculations of hadronic vacuum polarization and hadronic light-by-light scattering quantities, starting with the HVP, which has now reached sub-percent precision and requires a careful understanding of all sources of systematic errors.
