Thanks to the changes in #9190, Prefect now uses default values for any required keys missing from your project’s configuration. ‏‏‎ ‎ 🕑 Streamlined cancellation for scheduled flow runs In response to challenges cancelling scheduled flow runs, #8414 introduces a new flow orchestration rule. This rule ensures scheduled flow runs that haven’t started and lack an infrastructure PID skip the
