   Previously, this interface had a `connections` field, which represented the number of active connections on the current node that had not expired. This means that even if the MQTT connection has been disconnected, as long as the client has a persistent session, it would still be counted in the `connections` field. The newly added `live_connections` field specifically counts the number of clients with MQTT connections that have not been disconnected.
 
+- Added 3 random SQL functions to the rule engine [#11113](https://github.com/emqx/emqx/pull/11113).
+
+  - random(): Generates a random number between 0 and 1 (0.0 =< X < 1.0).
+  - uuid_v4(): Generates a random UUID (version 4) string.
+  - uuid_v4_no_hyphen(): Generates a random UUID (version 4) string without hyphens.
+
 ## Bug fixes
 
 - Fixed an issue where the rule engine was unable to access variables exported by `FOREACH` in the `DO` clause [#10620](https://github.com/emqx/emqx/pull/10620).

   此前该接口中有一个 `connections` 字段，它代表当前节点上会话未过期的连接数量。这意味着即使 MQTT 连接已经断开，只要客户端保持了会话，它仍然会被统计在 `connections` 中。新增的 `live_connections` 字段则仅仅统计 MQTT 连接未断开的客户端数量。
 
+- 规则引擎新增了三个随机函数 [#11113](https://github.com/emqx/emqx/pull/11113)。
+
+  - random()：生成 0 到 1 之间的随机数 (0.0 =< X < 1.0)。
+  - uuid_v4()：生成随机的 UUID (version4) 字符串。
+  - uuid_v4_no_hyphen()：生成随机的不带连词符的 UUID (version4) 字符串。
+
 ## 修复
 
 - 修复规则引擎无法在 `DO` 子句中访问 `FOREACH` 导出的变量的问题 [#10620](https://github.com/emqx/emqx/pull/10620)。
