+Airflow 2.9.3 (2024-07-02)
+--------------------------
+
+Significant Changes
+^^^^^^^^^^^^^^^^^^^
+
+Time unit for ``scheduled_duration`` and ``queued_duration`` changed.
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+``scheduled_duration`` and ``queued_duration`` metrics are now emitted in milliseconds instead of seconds.
+
+By convention all statsd metrics should be emitted in milliseconds, this is later expected in e.g. prometheus' statsd-exporter. (#37936)
