Symfony\Component\Security\Core\User\UserInterface::equals() has moved to Symfony\Component\Security\Core\User\EquatableInterface::isEqualTo().

• Symfony\Component\Security\Core\User\UserInterface::equals() has moved to Symfony\Component\Security\Core\User\EquatableInterface::isEqualTo().

  You must rename the equals() method in your implementation of the User class to isEqualTo() and implement EquatableInterface. Apart from that, no other changes are required.

  Alternatively, you may use the default implementation provided by AbstractToken::hasUserChanged() if you have no need of custom comparison logic. In this case, do not implement EquatableInterface and remove your comparison method.

  Before:

  class User implements UserInterface
  {
    // ...
    public function equals(UserInterface $user) { /* ... */ }
    // ...
  }

  After:

  class User implements UserInterface, EquatableInterface
  {
    // ...
    public function isEqualTo(UserInterface $user) { /* ... */ }
    // ...
  }

UserEquatableInterfaceFixer - fixes occurance of method in classes directly extending UserInterface.

We should support here case when UserInterface is aliased in a use statement. Worth of thinking is approach to instantiate a class and check implementing of interface via instanceof.
