  Recent developments in the public code $\texttt{FeynHiggs}$ for the
prediction of the Standard Model-like Higgs mass in the Minimal Supersymmetric
Standard Model are presented. Improvements in the prediction based on an
effective-field theory concern the cases of multi-scale hierarchies where the
gluino is much heavier than the sfermions or where the additional Higgs bosons
have masses between the electroweak and supersymmetry scales. The fixed-order
part is improved by a re-implementation and extension of the two-loop
corrections, now containing the contributions of orders
$\big(\alpha_t+\alpha_b\big)\cdot\big(\alpha_t+\alpha_b+\alpha_s\big)$ in the
limit of vanishing electroweak gauge couplings for all implemented
renormalization schemes. The updated version has a significantly improved
numerical stability and thus an enhanced range of applicability for scenarios
with heavy supersymmetric particles. All updates will be included in the
upcoming version $\texttt{FeynHiggs-2.19.0}$.
