The implications of precise new Z- and W-mass and weak-neutral-current data for the top-quark and Higgs-boson masses are analyzed. It is found that (a) sin2W=0.2260.005 for arbitrary mt and for all MH<1 TeV; (b) mt<210 GeV at 90% C.L.; (c) mt>40 GeV at 90% C.L., even if the direct lower limit mt>78 GeV does not apply; and (d) there is no constraint on the Higgs-boson mass.
