* In Symfony 2.7 a small BC break was introduced with the new choices_as_values
option. In order to have the choice values populated to the html value attribute
you had to define the choice_value option. This is now not any more needed.
Before:
```php
$form->add('status', 'choice', array(
'choices' => array(
'Enabled' => Status::ENABLED,
'Disabled' => Status::DISABLED,
'Ignored' => Status::IGNORED,
),
'choices_as_values' => true,
// important if you rely on your option value attribute (e.g. for JavaScript)
// this will keep the same functionality as before
'choice_value' => function ($choice) {
return $choice;
},
));
```
After (Symfony 2.8+):
```php
$form->add('status', ChoiceType::class, array(
'choices' => array(
'Enabled' => Status::ENABLED,
'Disabled' => Status::DISABLED,
'Ignored' => Status::IGNORED,
),
'choices_as_values' => true
));
```
* Returning type instances from `FormTypeInterface::getParent()` is deprecated
and will not be supported anymore in Symfony 3.0. Return the fully-qualified
class name of the parent type class instead.

* The `request` service was removed. You must inject the `request_stack`
service instead.
