+Dag Versioning
+~~~~~~~~~~~~~~
+
+In Airflow 3, Dags are versioned automatically when their definition changes.
+A new Dag version is created whenever the DAG structure is modified, for example when tasks or dependencies are added, removed, or updated.
+
+Each Dag run is associated with the version of the Dag that existed at the time
+the run was scheduled. Changes made to a Dag after a run has been scheduled do not affect already running or completed DAG runs.
