  We discuss the parameter spaces of supersymmetry (SUSY) scenarios taking into
account the improved Higgs-mass prediction provided by FeynHiggs 2.14.1. Among
other improvements, this prediction incorporates three-loop
renormalization-group effects and two-loop threshold corrections, and can
accommodate three separate mass scales: m_{\tilde q} (for squarks), m_{\tilde
g} (for gluinos) and m_{\tilde\chi} (for electroweakinos). Furthermore, it
contains an improved treatment of the DRbar scalar top parameters avoiding
problems with the conversion to on-shell parameters, that yields more accurate
results for large SUSY-breaking scales. We first consider the CMSSM, in which
the soft SUSY-breaking parameters m_0 and m_{1/2} are universal at the GUT
scale, and then sub-GUT models in which universality is imposed at some lower
scale. In both cases, we consider the constraints from the Higgs-boson mass M_h
in the bulk of the (m_0, m_{1/2}) plane and also along stop coannihilation
strips where sparticle masses may extend into the multi-TeV range. We then
consider the minimal anomaly-mediated SUSY-breaking (mAMSB) scenario, in which
large sparticle masses are generic. In all these scenarios the substantial
improvements between the calculations of M_h in FeynHiggs 2.14.1 and FeynHiggs
2.10.0, which was used in an earlier study, change significantly the preferred
portions of the models' parameter spaces. Finally, we consider the pMSSM11, in
which sparticle masses may be significantly smaller and we find only small
changes in the preferred regions of parameter space.
