 ## 更新日志
 
+### 1.3.0
+
+- 更新并适配`dynamic-datasource-spring-boot-starter`至`3.4.1`版本；
+- 更新并适配`spring-boot-starter-web`至`2.1.1.RELEASE`版本；
+- 新增`SaaSDataSourceClassResolver`来解析注解标记的类，原因是`dynamic-datasource-spring-boot-starter`在`3.1.1`版本后删除了本工具之前使用的对应API，所以只能本工具自己再实现一个；
+- 支持`SPI`，开发者可以省略`driverClassName`配置了。
+
 ### 1.2.0
 
-- 更新并适配`dynamic-datasource-spring-boot-starter`至3.1.1版本；
+- 更新并适配`dynamic-datasource-spring-boot-starter`至`3.1.1`版本；
 - 优化了`SaaSDataSource`，底层改为使用`ArrayDeque`来实现栈；
 - 增加`SaaSDataSource.removeAll`方法，可强制移除所有数据源，包含DynamicDataSource上下文中的数据源。如果你不确定业务流程完成后是否还有残留数据，可在最后（比如拦截器的`afterCompletion`中）调用此方法来确保移除。
