+##### [FLINK-32548](https://issues.apache.org/jira/browse/FLINK-32548)
+The watermark alignment is ready for production since Flink-1.18, which completed a series of bug fixes and improvements related to watermark alignment.

+Release notes - Flink 1.18
+
+These release notes discuss important aspects, such as configuration, behavior or dependencies,
+that changed between Flink 1.17 and Flink 1.18. Please read these notes carefully if you are
+planning to upgrade your Flink version to 1.18.
+

+Clusters & Deployment
+
+
+
+
+Table API & SQL
+
+Unified the max display column width for SqlClient and Table APi in both Streaming and Batch execMode
+
+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.

+
+"FLINK-32610"	"JSON format supports projection push down"	"The JSON format introduced JsonParser as a new default way to deserialize JSON data. JsonParser is a Jackson JSON streaming API to read JSON data which is much faster and consumes less memory compared to the previous JsonNode approach. This should be a compatible change, if you encounter any issues after upgrading, you can fallback to the previous JsonNode approach by setting `json.decode.json-parser.enabled` to `false`. "

+
+
+"FLINK-32486"	"FLIP-324: Introduce Runtime Filter for Flink Batch Jobs"	"We introduced a runtime filter for batch jobs in 1.18, which is designed to improve join performance. It will dynamically generate filter conditions for certain Join queries at runtime to reduce the amount of scanned or shuffled data, avoid unnecessary I/O and network transmission, and speed up the query. Its working principle is building a filter(e.g. bloom filter) based on the data on the small table side(build side) first, then passing this filter to the large table side(probe side) to filter the irrelevant data on it, this can reduce the data reaching the join and improve performance. \r\n"
