February 2026 — potiuk/airflow. Focused on correctness and stability in DAG run handling. Delivered a targeted bug fix for TaskInstance.get_dagrun edge-case where a dag_run marked as loaded but stored as None could cause an incorrect result. The fix ensures get_dagrun returns the actual DagRun object, with a regression test added to guard against similar regressions. This change reduces runtime errors in task scheduling and improves overall DAG reliability.
