 + The expression index feature. The expression index is also called the function-based index. When you create an index, the index fields do not have to be a specific column but can be an expression calculated from one or more columns. This feature is useful for quickly accessing the calculation-based tables. See [Expression index](/sql-statements/sql-statement-create-index.md) for details. (Introduced in v4.0)

 | [`tidb_enable_enhanced_security`](/system-variables.md#tidb_enable_enhanced_security) | Newly added | Indicates whether the TiDB server you are connected to has the Security Enhanced Mode (SEM) enabled. This variable setting cannot be changed without restarting the TiDB server. |
 | [`tidb_enforce_mpp`](/system-variables.md#tidb_enforce_mpp-new-in-v51) | Newly added | Controls whether to ignore the optimizer's cost estimation and to forcibly use the MPP mode for query execution. The data type of this variable is `BOOL` and the default value is `false`. |
-| [`tidb_partition_prune_mode`](/system-variables.md#tidb_partition_prune_mode-new-in-v51) | Newly added | Specifies whether to enable dynamic prune mode for partitioned tables. This feature is experimental. The default value of this variable is `static`, which means the dynamic mode for partitioned tables is disabled by default.  |
