Release 3.0.13 19/09/09

Gzipped tarred [source 3.0.13 | RPC manual | RPV manual | documentation]:
Bug-fixed sfermion loop corrections. Small sub-percent level corrections to physical masses. Thanks to Akin Wingerter.
14/09/09 [source 3.0.12] Bug-fixed sup loop corrections. Small sub-percent level corrections to physical masses. Thanks to Akin Wingerter.
27/08/09 [source 3.0.11] Small bug fixes in charged Higgs mass and neutral Higgs mass loop correcions. Thanks to Akin Wingerter.
22/07/09 [source 3.0.10] A bug was introduced in 3.0.8, which meant that the SLHA2 with flavour or RPV would only output in SLHA1 format. If you haven't noticed, then it almost certainly hasn't affected your results.
10/07/09 [source 3.0.9] From 3.0 SOFTSUSY was not flagging regions of bad electroweak symmetry breaking correctly. This has now been fixed. Thanks to Akin Wingerter.
18/06/09 [source 3.0.8] Non-universal Higgs mass calls bug-fixed: in version 3.0, a bug was introduced which meant that the alternative SUSY-scale boundary conditions options wouldn't produce viable points. Thanks to Nazila Mahmoudi
21/05/09 [source 3.0.7] Small per mille errors in heavier higgs mass calculations: omission of some Goldstone diagrams in mA and factor of 2 missing in higgs contribution. Tadpoles used to calculate higgs masses now updated to latest iteration rather than the previous one. Thanks go to Pietro Slavich.
07/05/09 [source 3.0.6] Internal error labelling of mA and mH bug-fixed: will have a negligible effect unless the mA-mH splitting is large. Thanks to Pietro Slavich.
25/04/09 [source 3.0.5] There was a bug in SLHA2 when one used both flavour violation and specified EXTPARS. Fixed now - thanks to Pietro Slavich.
23/04/09 [source 3.0.4] Flavour violating boundary condition in SLHA2 fixed: previously was ignoring off-diagonal elements of MSU2IN, MSQ2IN etc offered by user. Thanks to Pietro Slavich.
21/04/09 [source 3.0.3] Switched flavour mixing in RPV case back on: thanks to Marja Hanussek.
18/03/09 [source 3.0.2]
Sneutrino VEVs were accidentally switched off in previous versions. This is fixed in 3.0.2: thanks to Marja Hanussek for noticing the bug. This will only affect results using lepton number violating couplings.
11/03/09 [source 3.0.1]
Inclusion of R-parity violation into SOFTSUSY. Inclusion of flavour violation interface to SLHA2 input/output format. Several minor bug fixes in loop corrections of chargino/neutralino masses. v3.0.1 has the flavour parts of SLHA2 fixed. Thanks to Pietro Slavich.

Release 2.0.18 21/05/08

BUG-fixes: Gzipped tarred [source 2.0.18 | manual | documentation]: bug-fixed Z radiative correction to neutralino mass. Per mille differences resulting. Thanks to R Ruiz.
05/03/08: [source 2.0.17] More bugs in form of charged Higgs loops introduced by recent "bug fixes" - it should all be fixed in this version.
03/03/08: [source 2.0.16] More bugs in sign of charged Higgs loops in Higgs masses introduced in 2.0.15: thanks to Roberto Ruiz. 2.0.15 could have Higgs masses out by 3-4 GeV for heavy points and other sfermions out by a percent or so.
11/02/08: [source 2.0.15] Bug-fixed sign of charged Higgs corrections, introduced in v2.0.1. Could change slepton masses by several percent in some regions of parameter space. Thanks to J Kersten and W Porod.
09/08/07: [source 2.0.14] Bug-fixed tan beta and Higgs VEV RGEs: added Feynman gauge dependent pieces. Numerically, this makes a negligible difference (smaller than 10^-5 fractional error in all masses/mixing angles in MSUGRA). Thanks to A Shelpnyakov
09/07/07 [source 2.0.13] now works with negative m0 values in msugra - request from A Pukhov
28/06/07 [source 2.0.12] minor bug-fix in slha output file - spaces added so that SUSYHIT can read it. Thanks to S Sekmen
13/02/07 [source 2.0.11] small bug-fix in higgs mass squared parameters in the EXTPAR option input of SLHA files. Thanks to Steve Martin.
23/01/07 [source 2.0.10] Bug-fixed D0 Passarino-Veltman function - special cases now handled correctly (these are very unlikely to affect your results). Thanks to Shandou Tetsuo.
15/01/07 [source 2.0.9] bug-fixed loop corrections to neutralino mass. Negligible change to neutralino_1 mass, but heavier neutralino masses change by a percent or so at SPS1a. Thanks to Steve Kom.
07/09/06 [source 2.0.8] Bug-fixed 1-loop threshold correction to sneutrino mass. Resulting pole mass changes very slightly. Thanks to J Kersten.

25/04/06 [source 2.0.6] at high masses, there were sometimes convergence problems associated with numerical rounding errors in the p=0 limit of Passarino-Veltman functions. This has now been fixed by adding more tolerance before going to p=0.
20/02/06 [source 2.0.5 ] small error in two-loop term of right-handed charged slepton mass squared RGE fixed. Thanks to R Ruiz.
17/01/06 [ source 2.0.4 ]: mistake introduced in 2.0.3 in charged Higgs loop corrections to neutral higgs masses fixed. Thanks to R Ruiz for flagging the error.
14/11/05 [ source 2.0.3 ]: sbottom/stop mass ordering debugged:
program would sometimes crash due to inconsistent mass ordering. No changes to calculation, except of fine-tuning. ht fine-tuning now not included by default.
27/10/05 [ source 2.0.2 ]: grid of Q-values now conforms to SLHA definition. No changes to calculation.

26/08/05 [ source 2.0 ]
Upgraded accuracy: full 2-loop MSSM RGEs default, full 1-loop MSSM threshold corrections.
Simpler user interface: massIn has been done away with. To change Standard Model inputs, use either a main program like main.cpp for a scan, or the SUSY les Houches Accord Input format. softpoint.x otherwise uses default Standard Model inputs. Deleted confusing general boundary conditions option in SOFTSUSY format - use the SLHA.
SUSY Les Houches Accord updated and corrected. Isajet7.64 interface debugged.
mgluino now calculated at Q=MSUSY
number of loops in scalar RGEs promoted to a changeable global variable
