7+
* The `Role` and `SwitchUserRole` classes are deprecated and will be removed in 5.0. Use strings for roles
8+
instead.
9+
* The `RoleHierarchyInterface` is deprecated and will be removed in 5.0.
10+
* The `getReachableRoles()` method of the `RoleHierarchy` class is deprecated and will be removed in 5.0.
11+
Use the `getReachableRoleNames()` method instead.
12+
* The `getRoles()` method of the `TokenInterface` is deprecated. Tokens must implement the `getRoleNames()`
13+
method instead and return roles as strings.
714
* Made the `serialize()` and `unserialize()` methods of `AbstractToken` and
815
`AuthenticationException` final, use `getState()`/`setState()` instead
