We present an updated and improved global fit analysis of current flavor and electroweak precision observables to derive bounds on unitarity deviations of the leptonic mixing matrix and on the mixing of heavy neutrinos with the active flavours, which is motivated by the latest experimental updates on key observables such as $V_{ud}$, the Z invisible width and the W mass.
