- NMSSM specific radiative corrections to CP-odd and charged Higgs masses from chargino/neutralino loops have been added for "Higgs precision = 0".
- Chargino/neutralino 1-loop corrections to the CP-even Higgs masses use parameters at the scale QSTSB (resumming some large logarithms), and some NMSSM specific large logarithms have been added for "Higgs precision = 0".

Hence a first compilation of the code and a calculation of the relic density takes longer than before. In relden.F, virtual decays can be switched off setting setVVdecay(0) instead of the default setVVdecay(1).

- The experimental constraint on dark matter relic density is now 0.1187 ± 0.0017 (arXiv:1303.5076), but one has to allow for theoretical errors which are difficult to estimate. The default window in init.f is 0.1187 ± 0.0085, but can be modified by the user.
- New interface between NMSSMTools and micrOMEGAs 3.0 using the full Higgs effective lagrangian with parameters computed at the same precision level as for Higgs masses and couplings. These parameters can be found in the BLOCK EFFECTIVE_COUPLINGS at the end of the output file *spectr*.
- With "Higgs precision = 1 or 2", the relic density and the direct detection cross sections are computed by micrOMEGAs with the correct Higgs masses (previously micrOMEGAs used always the Higgs masses as computed with "Higgs precision = 0").
- The diagonal chargino loop contributions to H/A → Zγ are included, with thanks to Peiwen Wu for discussions.
30.01.2013: version 3.2.4

- Improvement of the numerical integration of the Boltzmann equations inside micrOMEGAs.
- CP-odd Higgs mixing corrected (for PFLAG > 0 only).
- The fine-tuning with respect to the input parameters is computed following arXiv:1107.2472 (the command "CALL FTPAR(PAR,...)" in MAIN is commented for scans).
7.10.2011: version 3.0.2
- In NMSDECAY: a warning appears on the screen if QCD corrections to colored sparticle decay widths are negative and larger than the tree level widths. Then the relative corrections "corr", leading to a negative width when added according to (1+corr), are replaced by 1/(1-corr).
- The measured (not computed) W and Z widths are added to the output of NMSDECAY.
- The BLOCKs for parameters at the GUT scale in the SLHA output of NMHDECAY and NMSPEC are renamed.

With special thanks to Margarete Muhlleitner, Abdelhak Djouadi and Yann Mambrini.
- Default compiler for LINUX is set to gfortran (f77 is no longer recommended due to potential problems with complex functions in NMSDECAY).
17.5.2011: version 2.3.7
- Charged Higgs mass with complete 1-loop and Yukawa induced 2-loop corrections (if improved corrections to Higgs masses are switched on), with thanks to Khiem Hong Phan and Pietro Slavich.

13.05.2008: version 2.0.0
- The architecture of the code has been modified: From the version 2.0.0 onwards, the task to be performed by an input file is independent from its name. However, the task to be performed by an input file must be specified in the BLOCK MODSEL at the beginning, see the new description README.
- The routines NMGMSB have been added, which allow for boundary conditions specified by gauge mediated supersymmetry breaking.
- SM error bars for the muon anomalous magnetic moment have been updated. The SM hadronic contribution to (g-2)μ is estimated from e+e- data only, data from τ decays is ignored; consequently the experimental BNL result differs from the SM by ~3σ. If the line "CALL MAGNMU(PAR,PROB)" is present in the main routines, it is checked whether a point in parameter space differs by at most by 2σ from the experimental result. Hence, points in parameter space for which the SUSY contribution is too small (or vanishing or of the wrong sign) generate warnings and are considered as phenomenologically excluded. If this constraint is considered as too strong by the user it is enough to comment the line "CALL MAGNMU(PAR,PROB)" in the main program.
- Experimental constraints from the Tevatron on sbottoms updated.
17.03.2008: version 1.3.0
- The muon anomalous magnetic moment is computed (to two loops) according to arXiv:0710.3714. A warning is issued if the SUSY contribution including theoretical errors is less than ~10-9 or larger than ~5x10-9.
- The input of the soft parameters of the first two generations is simplified for the versions NMHDECAY.
- The versions NMSPEC_GRID and _RAND allow to scan over non-universal soft parameters at the GUT scale.
- A script "run" is added which allows to run user-defined input files.

- Corrected 2 loop RGE for Aμ.
20.02.2008: version 1.2.4

- The smuon masses (and the trilinear coupling Aμ) are treated separately from the selectron masses.
- Small bug in the error management (if PROB(I) < 0) corrected.
08.02.2008: version 1.2.3

12.07.2007: version 1.1.1
- Improved convergence of NMSPEC near focus point regions.

11.06.2007
- Bug in the large tan(β) corrections to the branching ratios (in decay.f) corrected, with thanks to Iris Rottlaender (no change of version number).
30.03.2007
- Bug in the error management in NMHDECAY in case of negative Higgs masses squared corrected (no change of version number).
27.03.2007: version 1.1.0
- The MSSM-like parameter MA at MSUSY can be used as input instead of Aλ (within NMHDECAY, NMHDECAY_SCAN or NMHDECAY_GRID).
- Improved diagonalisation of Higgs mass matrices (avoids problems in cases with huge mass differences).
- Bug in the calculation of the Higgs wave function renormalisation constants Z in the case MA ≫ MSUSY corrected.
- If soft Higgs masses - as computed internally in NMHDECAY - are much larger than the SUSY scale, a warning is indicated.
- The micrOMEGAs version included in the NMSSMTools package has been updated:
- Bugs in the calculation of the Higgs widths in micrOMEGAs corrected.
- If the Higgs widths computed by micrOMEGAs are still unreliable (which could affect the relic density if the LSP annihilates through a Higgs resonance) a warning is indicated in the output file.
31.01.2007: version 1.0.2
- Bug in the Higgs loop corrections to MHiggs corrected.
08.01.2007: version 1.0.1
