* The new config have been introduced: `remote.log.metadata.topic.min.isr` with 2 as default value. You can correct the min.insync.replicas for the existed __remote_log_metadata topic via kafka-configs.sh if needed. For further details, please refer to [KIP-1235](https://cwiki.apache.org/confluence/x/yommFw).
* The new config prefix `remote.log.metadata.admin.` has been introduced. It allows independent configuration of the admin client used by `TopicBasedRemoteLogMetadataManager`. For further details, please refer to [KIP-1208](https://cwiki.apache.org/confluence/x/vYqhFg).
* The `kafka-streams-scala` library is deprecated as of Kafka 4.3 and will be removed in Kafka 5.0. For further details, please refer to the [migration guide](/{version}/streams/developer-guide/scala-migration).
+ * Kafka Streams now supports opt-in headers-aware state stores for DSL operators via the new `dsl.store.format` config (`DEFAULT` or `HEADERS`) and the `DslStoreFormat` enum on `DslKeyValueParams`, `DslWindowParams`, and `DslSessionParams`. For further details, please refer to [KIP-1285](https://cwiki.apache.org/confluence/display/KAFKA/KIP-1285%3A+DSL+Opt-in+Support+for+Headers-Aware+State+Stores).
