  "abstract": "We report on two recent calculations on the inclusive radiative decay $\\bar B\\to X_s γ$, notably multi-parton contributions at NLO and the $Q_{1,2}-Q_7$ interference at NNLO for the physical value of the charm-quark mass. The former calculation formally completes $\\bar{B} \\rightarrow X_s γ$ at NLO in QCD at leading power, the latter removes a long-standing $\\pm 3\\%$ uncertainty arising from interpolation in $m_c$. The updated Standard-Model prediction for the CP- and isospin-averaged branching ratio reads ${\\mathcal B}_{s γ}^{\\rm SM} = (3.54 \\pm 0.14)\\times 10^{-4}$ for photon energies $E_γ> 1.6\\,{\\rm GeV}$ in the $B$-meson rest frame. This value is in good agreement with the current experimental average ${\\mathcal B}_{s γ}^{\\rm exp} = (3.49 \\pm 0.19)\\times 10^{-4}$.",
