releases/release-5.4.0.md

@@ -79,6 +79,12 @@ In v5.4, the key new features or improvements are as follows:
 - Since v5.4.0, if you create a SQL binding for an execution plan that has been cached via Plan Cache, the binding invalidates the plan already cached for the corresponding query. The new binding does not affect execution plans cached before v5.4.0.
 - In v5.3 and earlier versions, [TiDB Data Migration (DM)](https://docs.pingcap.com/tidb-data-migration/v5.3/) documentation is independent of TiDB documentation. Since v5.4, DM documentation is integrated into TiDB documentation with the same version. You can directly read [DM documentation](/dm/dm-overview.md) without accessing the DM documentation site.
 - Remove the experimental feature of Point-in-time recovery (PITR) along with cdclog. Since v5.4.0, cdclog-based PITR and cdclog are no longer supported.

-    - Add a new system variable [`tidb_enable_paging`](/system-variables.md#tidb_enable_paging-new-in-v540) to determine whether to use paging to send Coprocessor requests. Enabling this feature can reduce the amount of data to process and to reduce latency and resource consumption [#30578](https://github.com/pingcap/tidb/issues/30578)
     - Support the `ADMIN {SESSION | INSTANCE | GLOBAL} PLAN_CACHE` syntax to clear the cached query plan [#30370](https://github.com/pingcap/tidb/pull/30370)
