Spring Security 5.5 was made available with breaking changes such as: renaming the DelegatingAuthorizationManager class to RequestMatcherDelegatingAuthorizationManager; and the ResourceKeyConverterAdapter class having been inlined. With the latter, there was no longer a need to simplify the configuration using the ConversionService interface in Spring Boot applications.
