Abstract We report on recent measurements of B meson decays to hadronic final states using electron-positron collisions at the Υ(4S) resonance collected from 2019 to 2022 by the Belle~II experiment and corresponding to an integrated luminosity of 362 fb1. We present new results to determine the quark-mixing parameter γ, performed combining Belle~II data with the full Belle data set, and analyses of two-body decays relevant for the determination of α. We also present recent results on branching ratios and direct {\it CP}-violating asymmetries of several B decays, which result in a competitive standard-model test based on the Kπ isospin sum rule and first observations of three new BD()KKS0 decays.
