  The experimental measurements of flavor-changing neutral-current B-meson
decays governed by b --> s + (gamma, l^+ l^-) transitions have entered a new
level of precision. Recent results by Belle, CDF, Babar, and LHCb on B -->K^(*)
l^+ l^- and B_s --> mu^+ mu^- decays are used in model-(in)dependent analyses
to test the Standard Model predictions and to derive stronger constraints on
nonstandard contributions. While in agreement with the Standard Model, they
still leave sizable room for new physics.
