- Update to 2.2.5:
* Interface changes
- Add preliminary support for HepMC3 (this interface is still
being tested)
* New features
- Improve decay showering off top quarks
- Improve single-top support and add examples and documentation
for its production channels
- Improve hadronisation and hadron decays for heavy flavour
production
- Introduce a user hook framework which allows users to easily
implement
event generation afterburners, see Examples/Userhook
- Add settings to output ME-only on-the-fly variations (along with
the full ones):
HEPMC_INCLUDE_ME_ONLY_VARIATIONS=1 (HepMC interface)
- New cut-off for parton-shower reweighting:
CSS_REWEIGHT_SCALE_CUTOFF=<pt_min>, default: 5 GeV2
this is more generally applicable than using a cut-off on the
number of reweighted emissions
- Improve support for on-the-fly variations of clustering steps
(reweight each step locally instead of doing it globally)
* Bugfixes
- Fix issue with the overweight treatment for negative weights
- Add missing shower weight in some event outputs, e.g. when using
`OUTPUT HepMC...[]`
- Fix issue with the overweight threshold for on-the-fly variations
- Fix issue with non-trivial beam spectra handling
- Fix possible issues with electron-"PDF" initialization
- Fix issue with the ISR-channel threshold for leptonic collider
- Fix X/Y functions in METOOLS (this is relevant for hadron decays)
- Fix crash in decay-channel sorting
- Fix crash when using EVENT_TYPE=HadronDecay
- Fix issue with CSS strong coupling values when using non-trivial
scale factors
- Fix issue with QSF variations for real emission calculations with
COMIX
- Fix crash when doing on-the-fly variations and invalid dipole
kinematics occur
- Fix issue in the interplay of the flux and the BIWeight for 1 -> n
processes
- Fix issue when using vertices with a vanishing coupling
- Fix rare "invalid amplitude" crashes
- Fix issues when adding limits for the number of t-channel propagators
in matrix elements
- Fix issue with checking PDF availability when enforcing jet vetoes
- Fix several compilation issues
- Add patch to fix ARM (and PPC) builds:
* SHERPA-MC-fix_arm_build.patch
- Refresh partially upstreamed patch:
* SHERPA-MC-no-return-in-non-void-function.patch
* Fri Sep 08 2017 badshah400@gmail.com
- Upstream released a new 2.2.4 tarball, so refresh sources.
* Sat Sep 02 2017 badshah400@gmail.com
- Update to version 2.2.4:
* Interface Changes:
- New default parameters for hadronisation model to improve
heavy flavour production fractions and meson/baryon ratios.
- Updates to Recola interface with some new parameter (names),
please refer to the manual.
- Make STRICT_METS the default scale setter to guarantee full
scale setting accuracy for unweighted events.
* New features
- Availability of DIRE NLO parton shower (cf.
arXiv:1705.00742). This is not (yet) the default shower, in
particular not in NLO-merged configurations.
- Higher numerical stability in parton shower kinematics
(re)construction.
- Add OVERWEIGHT_THRESHOLD allowing user to cap maximal weight
during event generation (cf. manual).
- Avoid spuriously large weights in NLO-merged samples due to
instable PDF ratios.
- Add interface for hadron-level selectors.
- Add Max_N_TChannels option in Amegic.
- Add possibility to identify partons which originate in the
hard decay handler.
- Restructure gzip support such that it can be switched off at
runtime (USE_GZIP).
- Enable on-the-fly reweighting for calculations with the
Higgs (Interference) add-on for HIGGS_INTERERENCE_MODE 1, 2,
3 or 4.
* Bugfixes
- Bugfix in NLO-matched parton shower emission for non-trivial
colour structures like in V+2j@NLO. This fixes an eta
asymmetry which was visible at the ~2% level in such
samples.
- BSM models through UFO: fix running coupling behaviour and
treatment of exotic color octets.
- Bugfix in random generator for Poisson distributions with
large mean values.
- Bugfixes for segfaults and compiler warnings with gcc 7.1.
- Bugfix for colour assignment in clustering for loop-induced
merged processes.
- Bugfix for decay showering in conjunction with NLO+PS
matching.
- Change BuildRequires HepMC-devel to HepMC2-devel: not compatible
with HepMC >= 3.0.
- Rename libSHERPA-MC-config to libSHERPA-MC0-config that follows
the shared lib versioning. In addition the ld.so.conf.d file is
also renamed to follow the shared lib version to make it
possible to install multiple versions of the shared lib.
- Rebase SHERPA-MC-no-return-in-non-void-function.patch and add
fixes for one more function showing the same issue in version
2.2.4.
- GCC >= 6.0 required, build fails with older GCC for openSUSE <=
1320.
* Fri Apr 28 2017 badshah400@gmail.com
- Update to version 2.2.3:
* Support for the Recola one-loop generator for QCD corrections.

non-void (bool) function that was not returning any data to
return "true".
* Mon Feb 13 2017 jengelh@inai.de
- Shared library package must only contain time-unique names;
split off libSHERPA-MC-config.
* Thu Feb 02 2017 adam.majer@suse.de

- Update to version 2.1.1 (Bug-fix release):
+ A bug related to MC@NLO has been fixed. This will affect the
total cross section in heavy quark production at the level of
few permille.
+ A bug related to parton showering in associated Higgs boson
production has been fixed.
+ A problem related to SQLite database locking on IBM BG/Q
systems has been solved.

containing extremely soft gluons.

accidentally being switched off has been fixed.

in MC@NLO event generation has been fixed.

state particle asymmetry, has been fixed. An update of the
underlying event parameters was necessary, invalidating MPI
grids generated with previous versions.

been updated and supplemented with a C++ interface.
+ A bug in the CS subtraction in DRED has been fixed.
- Changes from version 2.1.0:

and 1->3 decays allowed by the model, iterated to arbitrary
decay chain length, all decay steps are dressed with QCD
parton showers and QED corrections
+ MC@NLO H events with Comix, speeds up initialisation and
runtime
