  3. Supported platforms • CLHEP-1.8 has been successfully compiled under the following platform-compiler combinations: • Linux RedHat 6.1 egcs 1.1.2, gcc 2.95.2 • Linux RedHat 7.2, 7.3 gcc 2.95.2, gcc 3.2 • Sun Solaris 7 CC 5.2 • Sun Solaris 8 CC 5.3, CC 5.4 • OSF 4.0 cxx 6.1 • Multiple platforms KCC 4.0 • MacOS-X/Darwin gcc 2.95.2 • Windows 2000 VC++ 6.0

  4. Changes in the repository Evaluator: - fixed memory leak Geometry: - added isNear() method; Matrix: - bug fix: trace() used to return the sum of the elements in the first column, rather than the sum of the diagonal elements

  5. Changes in the repository GenericFunctions: - added Psi2Hydrogen and Abs classes - Variable class is up to date with the FNAL repository - got rid of the MetaProxy scheme: all the code that calls GSL has been put into *.icc files. StdHep, HepMC, HepPDT: - StdHep/printVersion.cc: problem fix - <string> has been replace with <string.h>; - HepPDT/TableBuilderT.hh: problem fix - map::remove() has been replaced with map::erase(); - HepMC::GenVertex and HepMC::GenParticle: added numChildren(), numParents(), hasChildren(), and hasParents() methods; - Updated documentation
