Please read these notes carefully if you are +planning to upgrade your Flink version to 1.18. + + +### Build System + +#### Support Java 17 (LTS) + +##### [FLINK-15736](https://issues.apache.org/jira/browse/FLINK-15736) +Apache Flink was made ready to compile and run with Java 17 (LTS). This feature is still in beta mode. +Issues should be reported in Flink's bug tracker. + + +### Table API & SQL + +#### Unified the max display column width for SqlClient and Table APi in both Streaming and Batch execMode + +##### [FLINK-30025](https://issues.apache.org/jira/browse/FLINK-30025) +Introduction of the new ConfigOption DISPLAY_MAX_COLUMN_WIDTH (table.display.max-column-width) +in the TableConfigOptions class is now in place. +This option is utilized when displaying table results through the Table API and sqlClient. +As sqlClient relies on the Table API underneath, and both sqlClient and the Table API serve distinct +and isolated scenarios, it is a rational choice to maintain a centralized configuration. +This approach also simplifies matters for users, as they only need to manage one configOption for display control. + +During the migration phase, while sql-client.display.max-column-width is deprecated, +any changes made to sql-client.display.max-column-width will be automatically transferred to table.display.max-column-width. +Caution is advised when using the CLI, as it is not recommended to switch back and forth between these two options. + +#### Introduce Flink Jdbc Driver For Sql Gateway +##### [FLINK-31496](https://issues.apache.org/jira/browse/FLINK-31496) +Apache Flink now supports JDBC driver to access sql-gateway, you can use the driver in any cases that +support standard JDBC extension to connect to Flink cluster. + +#### Extend watermark-related features for SQL +##### [FLINK-31535](https://issues.apache.org/jira/browse/FLINK-31535) +Flink now enables user config watermark emit strategy/watermark alignment/watermark idle-timeout +in Flink sql job with dynamic table options and 'Options' hint.
