+ Kafka Streams now provides rebalance listener metrics for "streams" groups to monitor the latency of rebalance callbacks.
+ The following metrics are available at the thread level: tasks-revoked-latency-avg, tasks-revoked-latency-max,
+ tasks-assigned-latency-avg, tasks-assigned-latency-max, tasks-lost-latency-avg, and tasks-lost-latency-max.
+ Note that these metrics are only populated when the Streams Rebalance Protocol (KIP-1071) is enabled.
+ Users migrating from the consumer rebalance listener metrics should update their monitoring dashboards and alerts to use these new streams-specific metrics.
+ More details can be found in KIP-1216.

Note: Kafka Streams 4.1.0 contains a critical memory leak bug (KAFKA-19748) that affects users of range scans and certain DSL operators (session windows, sliding windows, stream-stream joins, foreign-key joins). Users running Kafka Streams should consider upgrading directly to 4.1.1 when available.
