 - Fix `ssl.existingName` option of  helm chart not working [#9307](https://github.com/emqx/emqx/issues/9307).

+- Fix incorrect topic authorize checking of delayed messages [#9290](https://github.com/emqx/emqx/pull/9290).
+  Now will determine the actual topic of the delayed messages, e.g. `$delayed/1/t/foo` will be treated as `t/foo` in authorize checks.
+
+- Add property `code` to error response for `/authentication/sources/:type` [9299](https://github.com/emqx/emqx/pull/9299).
+
+- Align documentation for `/authentication/sources` with what we actually send [9299](https://github.com/emqx/emqx/pull/9299).
+
+- Fix query string parameter 'node' to `/configs` resource being ignored, return 404 if node does not exist [#9310](https://github.com/emqx/emqx/pull/9310/).

 - 修复 HTTP API `/gateways` 的返回状态码，未知 Gateway 名字应返回 `404` 而不是 `400` [#9268](https://github.com/emqx/emqx/pull/9268)。
 
+
 - 修复 helm chart 的 `ssl.existingName` 选项不起作用 [#9307](https://github.com/emqx/emqx/issues/9307)。

+- 修复延迟消息的主题授权判断不正确的问题 [#9290](https://github.com/emqx/emqx/pull/9290)。
+  现在将会对延迟消息中的真实主题进行授权判断，比如，`$delayed/1/t/foo` 会被当作 `t/foo` 进行判断。

+- 为 API `/authentication/sources/:type` 的返回值增加 `code` 字段 [9299](https://github.com/emqx/emqx/pull/9299)。
