- 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.
  + A bug related to CS subtraction with Comix has been fixed.
    This will eliminate possible large weights in events
    containing extremely soft gluons.
  + A bug related to the QED corrections on the hard interaction
    accidentally being switched off has been fixed.
  + A bug related to the contents of the HepMC::PdfInfo? object
    in MC@NLO event generation has been fixed.
  + A bug in the underlying event simulation, presenting as a final
    state particle asymmetry, has been fixed. An update of the
    underlying event parameters was necessary, invalidating MPI
    grids generated with previous versions.
  + The Python interface to access Sherpa's matrix elements has
    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:
  + Introduced SQLite as the preferred storage manager
  + Spin correlated decay chains (Comix only), includes all 1->2
    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
- Packaging changes:
  + Disable rivet bindings until SHERPA-MC builds with latest
    Rivet >= 2.1.2
  + BuildRequires on sqlite3-devel introduced since version 2.1.0
  + Package new binaries init_nlo.sh, make2scons, plot_graphs.sh.
