UPGRADE FROM 2.6 to 2.7
=======================
Router
------
* Route conditions now support container parameters which
can be injected into condition using `%parameter%` notation.
Due to the fact that it works by replacing all parameters
with their corresponding values before passing condition
expression for compilation there can be BC breaks where you
could already have used percentage symbols. Single percentage symbol
usage is not affected in any way. Conflicts may occur where
you might have used `%` as a modulo operator, here's an example:
`foo%bar%2` which would be compiled to `$foo % $bar % 2` in 2.6
but in 2.7 you would get an error if `bar` parameter
doesn't exist or unexpected result otherwise.
Form
----
* In form types and extension overriding the "setDefaultOptions" of the
AbstractType or AbstractExtensionType has been deprecated in favor of
overriding the new "configureOptions" method.
The method "setDefaultOptions(OptionsResolverInterface $resolver)" will
be renamed in Symfony 3.0 to "configureOptions(OptionsResolver $resolver)".
Before:
```php
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class TaskType extends AbstractType
{
// ...
public function setDefaultOptions(OptionsResolverInterface $resolver)
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Task',
));
}
```
After:
use Symfony\Component\OptionsResolver\OptionsResolver;
public function configureOptions(OptionsResolver $resolver)
