BETSE 0.8.4 (Kindlier Kaufmann) released. Significant changes include: * Default time step for the cutting event reverted to 0.0 s (i.e., the initial time step). While this and prior releases technically permit the cutting event to occur at subsequent time steps, doing so currently results in fatal exceptions during the "betse plot sim" phase and hence is highly discouraged. This issue will be permanently resolved in the next stable release of BETSE - to be released shortly.
