 - Adds a new feature to enable partial certificate chain validation for TLS listeners[#10553](https://github.com/emqx/emqx/pull/10553).
-  If partial_chain is set to 'true', the last certificate in cacertfile is treated as the terminal of the certificate trust-chain. That is, the TLS handshake does not require full trust-chain, and EMQX will not try to validate the chain all the way up to the root CA.
 
 - Adds a new feature to enable client certificate extended key usage validation for TLS listeners[#10669](https://github.com/emqx/emqx/pull/10669).

-- 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 partial_chain 设置为“true”，cacertfile 中的最后一个证书将被视为证书信任链的顶端证书。 也就是说，TLS 握手不需要完整的链，并且 EMQX 不会尝试一直验证链直到根 CA。
