Hi!

My pull request #1945 [1] was merged yesterday, that's great! 

Since the changes may break backwards compatibility I suggest something like the following is added to the release notes regarding the Spring Security adapter:

The AdapterDeploymentContextBean has been replaced with AdapterDeploymentContextFactoryBean which is a Spring BeanFactory implementation for AdapterDeploymentContext. The constructor accepts either a Resource to specify where the keycloak.json resides (as before), or a KeycloakConfigResolver which will then resolve the configuration at runtime.
