                  Geant4 9.5-beta-01 Release Notes
                  --------------------------------

                                                            30 June 2011

                            Migration Notes
                            --------------- 

  o The CMake system for installation has been now extended to cover all
    features. The old Configure script is still kept for this Beta release
    but will be removed in the final release of December.
    A startup guide with basic instructions for installing Geant4 with CMake
    can be found in geant4.9.5.b01/cmake/INSTALL.g4cmake
    You're therefore encouraged to try it out and provide feedback!
  o Geant4 now comes with an embedded CLHEP module (currently based on
    version 2.1.0.1 of CLHEP), which includes a subset of the CLHEP library
    classes relevant for Geant4. It is therefore possible to choose not to
    install CLHEP as external library and use directly the embedded module.
    Use/installation of the embedded CLHEP module is triggered if no
    CLHEP_BASE_DIR variable is being set (or if using the default settings
    through CMake).
  o An additional package, 'expat', required by the new hadronic 'lend'
    module is embedded in 'externals' and is automatically built on Windows.
    On Linux or Mac, the 'expat' library available in the system is used
    instead.

        Option to use system CLHEP is automatically set to ON if the user
        has supplied a CLHEP_ROOT_DIR argument.
      o Added script UseGeant4.cmake providing a simple CMake module which
        users can include to setup the build of a basic Geant4 application.
        It sets definitions, include directories and compiler flags.
      o Added support for generation of DLL libraries on WIN32 platform.
      o Abilitated built-in dylib symbols on Mac for shared libraries;
        it is now no longer necessary to specify paths in DYLD_LIBRARY_PATH.
      o Automatically use GDML if user supplies XERCESC_ROOT_DIR argument
        as path to XercesC installation.
      o Providing full setup of environment from build and install trees,
        allowing developers to build applications directly using the build
        tree.
      o Fix for Unix platforms in setting the output directory for libraries.
        Partially addressing problem report #1200.
      o Added universal shell script skeleton for generating backward

        cascade, not after de-excitation.
      o G4NucleiModel: Added trailing effect. Added optional argument to
        reset() with list of collision points, for copying cascade state when

        is below the threshold.
      o New class G4AntiNuclElastic for simulation of elastic anti-A - A
        scattering.

        including Oxygen-18.

        corresponding class: G4ComponentCHIPShadronNuclearXS.
      o G4QGSParticipants: reduced energy of participant nucleons by binding
        energy. This increases excitation energy, as calculated by
        initial-final. Without this, excitation E often is close to 0, or

        Added corresponding commands in G4RadiactiveDecaymessenger.
        Set process subtype (fRadioactiveDecay = 210).
