+The fairness_id metric label is now capped at 1000 distinct values; additional fairness IDs are reported under the `other` label value. Flow control metric series for a fairness ID are removed when its flow is garbage collected. This bounds EPP memory and metrics-pipeline load, which were previously unbounded because the label derives from a client-controlled header.
