000004239 520__ $$aThe Belle II experiment has collected a 424 fb^-1 data set of e+e-  collisions produced by the asymmetric-energy SuperKEKB collider. Three-quarters of the data have a centre-of-mass energy equal to the mass of the \Upsilon(4S) resonance, which decays to B-meson pairs, allowing measurements of rare B decays, CP violation, and searches for lepton universality violation. Highlights include the first observation of B \to K \nu \bar{\nu} and measurements of lepton-universality in semitauonic B decays. We have also recorded a dedicated 19.2 fb^-1 data set away from the \Upsilon(4S), where we have made measurements related to the properties of the \Upsilon(10753), to probe its potentially exotic nature. Our first results related to charm hadron decays, which use the full data sample, are also presented.
