Release Note

The old planner of the Table & SQL API is deprecated and will be dropped in Flink 1.14. This means that both the BatchTableEnvironment and DataSet API interop are reaching end of life. Use the unified TableEnvironment for batch and stream processing with the new planner or the DataStream API in batch execution mode.
