<h3 id="v25-2-0-alpha-1-sql-language-changes">SQL language changes</h3>

- The `plan_cache_mode` session setting now defaults to `auto`, enabling generic query plans for some queries. [#135668][#135668]
- `SHOW JOBS` is now based on a new mechanism for storing information about the progress and status of running jobs. [#138104][#138104]
- `SHOW VIRTUAL CLUSTER WITH REPLICATION STATUS` now displays the `ingestion_job_id` column after the `name` column. [#138967][#138967]
- Since v23.2 table statistics histograms have been collected for non-indexed JSON columns. Histograms are no longer collected for these columns. This reduces memory usage during table statistics collection, for both automatic and manual collection via `ANALYZE` and `CREATE STATISTICS`. This can be reverted by setting the cluster setting `sql.stats.non_indexed_json_histograms.enabled` to `true`. [#139766][#139766]
