  We analyze the impact of the recent Feynman-diagrammatic (FD) two-loop
results for the mass of the lightest CP-even Higgs boson in the MSSM on the
theoretical upper bound for mh as a function of tan(beta). The results are
compared with previous results obtained by renormalization group (RG) methods.
The incorporation of dominant FD two-loop corrections into the decay width
\Gamma(h -> f \bar f) is also discussed.
