Upgrade Notes

For Table API: 1.15.0 and 1.15.1 generated non-deterministic UIDs for operators that make it difficult/impossible to restore state or upgrade to next patch version. A new table.exec.uid.generation config option (with correct default behavior) disables setting a UID for new pipelines from non-compiled plans. Existing pipelines can set table.exec.uid.generation=ALWAYS if the 1.15.0/1 behavior was acceptable due to a stable environment. See FLINK-28861 for more information.
