As far as EW aspects are concerned, I think not much changed in the last 
years. Some parameters could be updated, and it should be done if a new 
input is assembled anyhow. There are some aspects to remember in the 
context of the W/Z widths:

* There is a difference between providing the best prediction for 
Gamma_W/Z + confronting it with an exp. result and using Gamma_W/Z in 
cross-section predictions.

* In cross-section predictions for processes that include W/Z decays, 
such as in Higgs-strahlung or W/Z production processes, the total W/Z 
widths used in the resonance propagators should be calculated exactly to 
the same level of accuracy as used in the matrix-element calculation of 
the process. Only in this way, the "effective branching ratios" from the 
W/Z decays come out in the considered accuracy level consistently. These 
effective BRs result from the total width in the propagator and the 
effective partial width in the numerator that results from integrating 
out the decay kinematics. Using, e.g., "best" predictions for total 
Gamma_W/Z or even measured values, would result in some mismatch.

* The issue is of particular importance if several or even all decay 
channels can be analysed, because the effective branching ratios should 
add up to 1, reflecting unitarity.
