This werk only affects maintainers of custom special agents: Previously, when an error occurred when executing a special agent, the first exception line was displayed in the service summary of the Check_MK service. Since the last line is usually the most recent message, e.g. when displaying traceback, this werk changes the summary to be the last line.
