 **Version 5.0.0**
 * DEPRECATE ADD_CONCRETE_TYPE_REGISTRATION registration option. It basically does nothing anymore. See next point.
 * CHANGE adding registrations by super type always registers them by concrete type as well now. (Previously done with ADD_CONCRETE_TYPE_REGISTRATION). See DO_NOT_ADD_CONCRETE_TYPE_REGISTRATION for the reverse behaviour.
+* CHANGE RegistrationOptions enum name to RegistrationOption
+* DEPRECATE Usage of RegistrationOptions, please use RegistrationOption instead.
 
 **Version 4.0.0**
 * REMOVE deprecated module "dependency.d"
