> The Flink Kafka connector currently can't compile against Flink 1.20-SNAPSHOT. An example failure can be found at https://github.com/apache/flink-connector-kafka/actions/runs/8659822490/job/23746484721#step:15:169
> The {code:java} TypeSerializerUpgradeTestBase{code} has had issues before, see FLINK-32455. See also specifically the comment in https://issues.apache.org/jira/browse/FLINK-32455?focusedCommentId=17739785&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17739785
> Next to that, there's also FLINK-25509 which can only be supported with Flink 1.19 and higher. 
> So we should:
> * Drop support for 1.17 and 1.18
> * Refactor the Flink Kafka connector to use the new {code:java}MigrationTest{code}
> We will support the Flink Kafka connector for Flink 1.18 via the v3.1 branch; this change will be a new v4.0 version with support for Flink 1.19 and the upcoming Flink 1.20
