We describe the Fortran code CPsuperH2.3, which incorporates the following updates compared with its predecessor CPsuperH2.0. It implements improved calculations of the Higgs-boson masses and mixing including stau contributions. It incorporates the LEP limits on the processes e+ e- to H_i Z, H_i H_j and the CMS limits on H_i to taubar tau obtained from 4.6/fb of data at a centre-of-mass energy of 7 TeV. It also includes the Schiff-moment contributions to the electric dipole moments of Mercury and Radium 225, with several calculational options for the case of Mercury. These additions make CPsuperH2.3 a suitable tool for analyzing possible CP-violating effects in the MSSM in the era of the LHC and a new generation of EDM experiments.
