 - Fixed MQTT bridge TLS connection could not verify wildcard certificate from peer [#10094](https://github.com/emqx/emqx/pull/10094).
 
 - Fixed the problem that EMQX could not timely clear the disconnected MQTT connection information due to a large number of retained messages [#10189](https://github.com/emqx/emqx/pull/10189).
-  Before this fix, the `emqx_retainer` plugin and the connection cleanup process of emqx shared the same process pool.
+  Before this fix, the `emqx_retainer` plugin and the connection cleanup process of EMQX shared the same process pool.
   Therefore, if the process pool was blocked by a large number of retain messages, many disconnected MQTT connections would not be cleaned up in time.
   For more details, see [#9409](https://github.com/emqx/emqx/issues/9409).
   In this fix, we created a separate process pool for the `emqx_retainer` plugin to avoid this problem.

   如果该进程池被大量的 retain 消息下发任务阻塞时，许多已经掉线的 MQTT 连接将得不到及时清理。
   问题详情见 [#9409](https://github.com/emqx/emqx/issues/9409)。
   在此修复中，我们给 `emqx_retainer` 插件创建了单独的进程池，从而避免了该问题。
