-    Before v7.4.0, when you use parallel multi schema change to commit multiple `ADD INDEX` operations in a single SQL statement, the performance is the same as using multiple independent SQL statements for `ADD INDEX` operations. However, after optimization in v7.4.0, the performance of adding multiple indexes in a single SQL statement has been greatly improved.

 * Support caching execution plans for non-prepared statements (GA) [#36598](https://github.com/pingcap/tidb/issues/36598) @[qw4990](https://github.com/qw4990)
 
     TiDB v7.0.0 introduces non-prepared plan cache as an experimental feature to improve the load capacity of concurrent OLTP. In v7.4.0, this feature becomes GA. The execution plan cache will be applied to more scenarios, thereby improving the concurrent processing capacity of TiDB.
