- max_instances renamed to max_running - consider_args parameter: if True, $max_running of this function with the same arguments can be running, else: $max_running of this function, no matter the arguments, can be running - discard_if_max_running: if True and there are already the maximum possible number of running functions running, cancel this task (previous default behavior), else: Wait for a spot to be free before running
