 At this point, as a spin-off the [http://th.physik.uni-frankfurt.de/~brat/hsd.html HSD project] was established, focusing on High Energy Heavy-Ion Collisions. This project is maintained by W.Cassing and E.Bratkovskaya totally detached from following development.

He also did the first high-energy calculations with photons where shadowing becomes important. In the following years

 ion collisions in the SIS energy region and above; as a major topic, he studied the influence of

 Later, also A. Larionov and K. Gallmeister joined the initiative. A. Larionov took care of the implementation of strangeness production and improved the baryon-baryon cross sections. Furthermore, he included a relativistic mean field in the propagation, which can now be used alternatively to the Skyrme mean field. In a joined effort, O.Buss and K.Gallmeister implemented the local ensemble

+the new code. Gaitanos and Larionov implemented another, relativistic version of the mean field and joined the code with a statistical method to describe fragment formation and decay. 
 
-In April 2008, the first source code release was published on this website under the GPL license.
+On the physics side O. Buss showed that the observed in-medium changes of the 2 pi strength could be well explained by a state-of-the-art treatment of final state interactions as they were possible now with the GiBUU code. He also published very detailed results on pion-nucleus interactions. Kai Gallmeister, on the high-energy side, went on to extract prehadronic interactions from a detailed comparison with the EMC and HERMES experiments and Tina Leitner obtained the first reliable results on neutrino-nucleus reactions, both for inclusive and exclusive reactions. Recently, '''Olga Lalakulich''' (Russia) joined this neutrino activity, concentrating on a good treatment of background terms in the pion-production channel. At the same time, '''Murat Kaskulov''' (Russia) worked with the code on an analysis of nuclear transparency measured at JLAB, with an eye on color transparency.
