 * Fixed a possible StackOverflow exception if an FMU returns a discard or error status code
 * Fixed a possible stall of the SIL Kit component if the FMU component terminates unexpectedly
 * FMU Importer erroneously started SIL Kit lifecycle even if the initialization of the FMU or Importer failed
+* Fixed a crash that occured if the FMU had array variables of Binary type.
