UPGRADE FROM 4.1 to 4.2
=======================
Security
--------
* Using the `has_role()` function in security expressions is deprecated, use the `is_granted()` function instead.
* Passing custom class names to the
`Symfony\Component\Security\Core\Authentication\AuthenticationTrustResolver` to define
custom anonymous and remember me token classes is deprecated. To
use custom tokens, extend the existing `Symfony\Component\Security\Core\Authentication\Token\AnonymousToken`
or `Symfony\Component\Security\Core\Authentication\Token\RememberMeToken`.
SecurityBundle
--------------
* Using the `security.authentication.trust_resolver.anonymous_class` and
`security.authentication.trust_resolver.rememberme_class` parameters to define
the token classes is deprecated. To use
custom tokens extend the existing AnonymousToken and RememberMeToken.
