We present an update on total and partial branching fractions and on CP asymmetries in the semi-inclusive decay B → X_sℓ⁺ℓ^-. Further, we summarize our results on branching fractions and CP asymmetries for semi-inclusive and fully-inclusive B → X_sγ decays. We present the first result on the CP asymmetry difference of charged and neutral B → X_sγ decays yielding the first constraint on the ratio of Wilson coefficients Im(C₈^eff/C₇^eff).
