########## docs/getting-started/upgrade.md: ########## @@ -49,7 +49,7 @@ type: docs * The `--max-partition-memory-bytes` option in `kafka-console-producer` is deprecated and will be removed in Kafka 5.0. Please use `--batch-size` instead. * Queues for Kafka ([KIP-932](https://cwiki.apache.org/confluence/x/4hA0Dw)) is production-ready in Apache Kafka 4.2. This feature introduces a new kind of group called share groups, as an alternative to consumer groups. Consumers in a share group cooperatively consume records from topics, without assigning each partition to just one consumer. Share groups also introduce per-record acknowledgement and counting of delivery attempts. Use share groups in cases where records are processed one at a time, rather than as part of an ordered stream. - * The Streams Rebalance Protocol ([KIP-1071](https://cwiki.apache.org/confluence/display/KAFKA/KIP-1071%3A+Streams+Rebalance+Protocol)) is now production-ready for its core feature set. This broker-driven rebalancing system designed specifically for Kafka Streams applications provides faster, more stable rebalances and better observability. For more information about the supported feature set, usage, and migration, please refer to the [Streams developer guide](/{version}/documentation/streams/developer-guide/streams-rebalance-protocol.html). + * The Streams Rebalance Protocol ([KIP-1071](https://cwiki.apache.org/confluence/display/KAFKA/KIP-1071%3A+Streams+Rebalance+Protocol)) is now production-ready for its core feature set.

For more information about the supported feature set, usage, and migration, please refer to the [Streams developer guide](/{version}/documentation/streams/developer-guide/streams-rebalance-protocol.html). Due to a critical bug in the offline migration code ([KAFKA-20254](https://issues.apache.org/jira/browse/KAFKA-20254)), we recommend against doing migrations from classic to streams groups in 4.2.0. Newly created streams groups are not impacted. Users planning to migrate should upgrade to a later release that includes the fix. Review Comment: I think we should clarify that's it's a broker side bug, and users need to upgrade their brokers, not KS clients to get the fix. -- This is an automated message from the Apache Git Service.
