3.1.1
A bug with a possible circular spring bean dependency was resolved in this release.
BeanMapper bean creation depended on the existence of an AuthenticationManager bean, this check resulted in a circular dependency because this spring-security bean will only be created untill WebMvcAutoConfiguration has been completed. And MergedFormConfig will be created during this step because it's a WebMvcConfigurer. To complete the cycle, MergedFormConfig depends on a BeanMapper bean.
