  • 2017-02-27: FlexibleSUSY 1.7.3 has been released. This version fixes a bug in the CMSSMCPV model file and implements missing limits of the threshold correction functions for HSSUSY [arXiv:1407.4081].
  • 2016-12-15: FlexibleSUSY 1.7.2 has been released. This version fixes a bug in the 2-loop and 3-loop SM-QCD contributions to the top pole mass and top Yukawa coupling in non-SUSY models.
  • 2016-10-15: FlexibleSUSY 1.7.1 has been released. This version includes GM2Calc 1.3.0 and simplifies the configuration options for FlexibleEFTHiggs.
  • 2016-09-19: FlexibleSUSY 1.7.0 has been released. This version includes FlexibleEFTHiggs and a Mathematica interface for the spectrum generators generated with FlexibleSUSY.
  • 2016-09-03: Standalone FlexibleEFTHiggs spectrum generators for the MSSM, NMSSM, E6SSM and NMSSM have been released.
