Hi Fred, one reason why this hasn't been updated is that Flink needs to ensure backwards compatibility. Hence, if the newer Kryo library serializes objects differently, then Flink would need to migrate old savepoints having been stored via the old Kryo serializer to the new format. This is currently not supported and afaik blocks upgrading this library.
