Abstract
The analysis of the newest data on the leptonic Z-decays and mW appears to reveal the first manifestations of electroweak radiative corrections. In fact, these data differ, at the level of 2σ, from their electroweak Born values, while they agree, to within 1σ, with the theoretical values which take the electroweak radiative corrections into account. Previous data were within 1σ in agreement with both sets of values.
