We discuss the parameter spaces of supersymmetry (SUSY) scenarios taking intoaccount the improved Higgs-mass prediction provided by FeynHiggs 2.14.1. Amongother improvements, this prediction incorporates three-looprenormalization-group effects and two-loop threshold corrections, and canaccommodate three separate mass scales: m_{\tilde q} (for squarks), m_{\tildeg} (for gluinos) and m_{\tilde\chi} (for electroweakinos). Furthermore, itcontains an improved treatment of the DRbar scalar top parameters avoidingproblems with the conversion to on-shell parameters, that yields more accurateresults for large SUSY-breaking scales. We first consider the CMSSM, in whichthe soft SUSY-breaking parameters m_0 and m_{1/2} are universal at the GUTscale, and then sub-GUT models in which universality is imposed at some lowerscale. In both cases, we consider the constraints from the Higgs-boson mass M_hin the bulk of the (m_0, m_{1/2}) plane and also along stop coannihilationstrips where sparticle masses may extend into the multi-TeV range. We thenconsider the minimal anomaly-mediated SUSY-breaking (mAMSB) scenario, in whichlarge sparticle masses are generic. In all these scenarios the substantialimprovements between the calculations of M_h in FeynHiggs 2.14.1 and FeynHiggs2.10.0, which was used in an earlier study, change significantly the preferredportions of the models' parameter spaces. Finally, we consider the pMSSM11, inwhich sparticle masses may be significantly smaller and we find only smallchanges in the preferred regions of parameter space.
