An updated version is presented of the Fortran code FeynHiggs for theevaluation of the neutral CP-even Higgs sector masses and mixing angles. Itdiffers from the previous version by a modification of the renormalizationscheme concerning the treatment of subleading terms at the one-loop level; thetwo-loop corrections, for which the leading contributions of O(alpha_t alphas)and O(alpha_t^2) are implemented, are not affected by the modifiedrenormalization prescription. Besides stabilizing the Higgs mass calculationsand avoiding unphysically large threshold effects, the mass of the lightestMSSM Higgs boson, m_h, is increased by 1-2 GeV for most parts of the MSSMparameter space.
