Here are the latest docs for Flink and the Apache Kafka connector. Looks like the version number aligns with the version of Flink for the connector: https://nightlies.apache.org/flink/flink-docs-release-1.17/docs/connectors/datastream/kafka/ Flink: 1.17.1 Kafka Connector: 1.17.1 Kafka: 3.5.0? Does the above combo of Flink and connector align with the latest stable version of Kafka, i.e., 3.5.0?

The Flink Kafka connector 1.17.1 has been tested against Kafka 3.2.3, see https://github.com/apache/flink/blob/release-1.17.1/flink-connectors/flink-connector-kafka/pom.xml#L38 However, since the Flink Kafka connector is in the process of being externalized, there's also Flink Kafka Connector 3.0.0 (which is compatible with Flink 1.17.1, That specific version does contain a couple of bugfixes that are not the 1.17.1 release, see https://lists.apache.org/thread/mff76c2hzcb1mk8fm5m2h4z0j73qz2vk
