Release Note

`FlinkKafkaConsumer` has been deprecated in favor of `KafkaSource`. To upgrade to the new version, please store the offsets in Kafka with `setCommitOffsetsOnCheckpoints` in the old `FlinkKafkaConsumer` and then stop with a savepoint. When resuming from the savepoint, please use `setStartingOffsets(OffsetsInitializer.committedOffsets())` in the new `KafkaSourceBuilder` to transfer the offsets to the new source.
