1.4.0

• #9 and #10: PHP-DI now resolves middlewares, route variable converters, error handlers and view handlers (instead of being limited to Closures by Silex). This is achieved by overriding the CallbackResolver.

In other words, this brings the resolution logic of enhanced controllers as services to all callbacks in Silex.

Example of a middleware resolved by PHP-DI:

class AuthMiddleware
{
    public function beforeRoute(Request $request, Application $app)
    {
        // ...
    }
}

$app->before([AuthMiddleware::class, 'beforeRoute']);
