 # 升级指南
+
 ## 从 0.3.0 升级至 0.4.0
+
 版本`0.4.0`提供了支持多商户号的[定时更新平台证书功能](README.md#定时更新平台证书功能)，不兼容版本`0.3.0`。推荐升级方式如下：
+
 - 若你使用了`ScheduledUpdateCertificatesVerifier`，请使用`CertificatesManager`替换：
+
 ```diff
 -verifier = new ScheduledUpdateCertificatesVerifier(
 -                new WechatPay2Credentials(merchantId, new PrivateKeySigner(merchantSerialNumber, merchantPrivateKey)),
 -                apiV3Key.getBytes(StandardCharsets.UTF_8));
 +// 获取证书管理器实例

 +// 向证书管理器增加需要自动更新平台证书的商户信息

 +// 从证书管理器中获取verifier
-+verifier = certificatesManager.getVerifier(mchId);
++verifier = certificatesManager.getVerifier(merchantId);
 ```
+
 - 若你使用了`getLatestCertificate`方法，请使用`getValidCertificate`方法替换。
