Description	Symbiotic 7 brings improvements in all parts of the tool. In particular, we integrated the advanced shape analysis implemented in Predator to our instrumentation process for memory safety checking. Further, we extended our slicer to correctly handle non-terminating programs. This new slicing is applied in termination analysis, where we also added instrumentation for detection of simple cycles in the program state space. The witness generation process changed as well.
