The anomalies in rare B decays endure. We present results of an updated global analysis that takes into account the latest experimental input – in particular the recent results on RK and BR(Bs → μ+μ−) – and that qualitatively improves the treatment of theory uncertainties. Fit results are presented for the Wilson coefficients of four-fermion contact interactions. We find that muon specific Wilson coefficients C9 ≃ −0.73 or C9 = −C10 ≃ −0.39 continue to give an excellent description of the data. If only theoretically clean observables are considered, muon specific C10 ≃ 0.60 or C9 = −C10 ≃ −0.35 improve over the Standard Model by
