Phalcon 1.3.0 Response redirect not working the same?

            $this->response->redirect(array(
                'for' => 'show-board',
                'board' => $this->request->getPost("board")
            ));

this used to work for me in 1.2.6, however in 1.3.0 this redirects me to http://my-url.com/Array ???

I think the documentation says you can pass an array like that, but in practice I just pass it a string:

$this->response->redirect('show-board/'.$this->request->getPost("board"));
