   The parameters of certain actions support using placeholder syntax to dynamically fill in the content of strings. The format of the placeholder syntax is `${key}`.
   Prior to the improvement, the `key` in `${key}` could only contain letters, numbers, and underscores. Now the `key` supports any UTF8 character after the improvement.
 
+- Adds a new feature to enable partial certificate chain validation for TLS listeners[#10553](https://github.com/emqx/emqx/pull/10553).
+  If TLS listener has `partial_chain` set to `cacert_from_cacertfile`,
+  the certificate in the `cacertfile` will be used as the `cacert` for chain path validation. If the `cacertfile` has a chain of certificates, the cert at the end of the file will be used as the `cacert` for path validation.

   某些动作的参数支持使用占位符语法，来动态的填充字符串的内容，占位符语法的格式为 `${key}`。
   改进前，`${key}` 中的 `key` 只能包含字母、数字和下划线。改进后 `key` 支持任意的 UTF8 字符了。
 
+- 增加了一个新的功能，为TLS监听器启用部分证书链验证[#10553](https://github.com/emqx/emqx/pull/10553)。
+  如果TLS监听器的 `partial_chain` 设置为 `cacert_from_cacertfile`,
+  `cacertfile` 中的证书将被用作链式路径验证的 `cacert` 。如果 `cacertfile` 文件有一连串的证书，文件末尾的证书将被用作路径验证的 `cacert`。
