The recent updates significantly enhance the RocketMQ broker with new rebalancing and dead-letter queue (DLQ) functionalities. A RebalanceLockManager was integrated into the BrokerRuntime for better message queue management. Several modules were restructured, including the introduction of the rebalance module and the modification of the SendMessageProcessor to handle retry and DLQ processing.

In the broker's heart, the messages fly,
With rebalancing locks, they touch the sky.
Retry and DLQ, now handled with grace,
In RocketMQ's embrace, they find their place.
