  Recent studies to finalize the systematic error estimates on the measurement
of the mass of the W boson at LEP2 are reviewed. Results including a new
preliminary value from Aleph are updated together with the world average which
is now 80.426 +- 0.034GeV/c2. The updated electroweak fit gives a 95% C.L.
upper limit on the mass of the Higgs boson of 211GeV/c2.
