  We update the upper bound on the lightest CP even Higgs mass in the NMSSM,
which is given as a function of tan(beta) and lambda. We include the available
one and two loop corrections to the NMSSM Higgs masses, and constraints from
the absence of Landau singularities below the GUT scale as well as from the
stability of the NMSSM Higgs potential. For m_top varying between 171.4 and 178
GeV, squark masses of 1 TeV and maximal mixing the upper bound is assumed near
tan(beta) ~ 2 and varies between 139.9 and 141.4 GeV.
