* Method `equals` of `Symfony\Component\Security\Core\User\UserInterface` has

moved to `Symfony\Component\Security\Core\User\EquatableInterface`.

You have to change the name of the `equals` function in your implementation

of the `User` class to `isEqualTo` and implement `EquatableInterface`.

Apart from that, no other changes are required to make it behave as before.

Alternatively, you can use the default implementation provided

by `AbstractToken:hasUserChanged` if you do not need any custom comparison logic.

In this case do not implement the interface and remove your comparison function.

Before:

class User implements UserInterface

{

// ...

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

// ...

}

After:

class User implements UserInterface, EquatableInterface

{

// ...

public function isEqualTo(UserInterface $user) { /* ... */ }

// ...

}
