    Release Notes: A new model of gamma nuclear interactions using the Bertini cascade was added. The Bertini model for pi-, K-, and Sigma- for nuclear capture at rest was introduced, along with the WentzelVI model for multiple scattering of e+ and e- above 100 MeV in all physics lists for HEP applications. Shen and Ion/proton cross-sections for ions are used. The cross-section for light ions including deuteron was improved. The INCL cascade model can now handle heavy-ion collisions. A new electro-nuclear interaction model has been added. A combination of FTF and Precompound models is used for anti-proton and anti-Sigma+. There were other enhancements and bugfixes.
