How to make buttons instead of a keyboard?

As I understand it, the API has been updated and now inline buttons are as follows:

Code for creating an array of buttons:

$inline_keyboard = array('inline_keyboard' => 
        array(
          array(
            array(
              'text' => 'Русский', 'callback_data' => '/set_language ru'
              ),
            array(
              'text' => 'English', 'callback_data' => '/set_language en'
              ), 
            array(
              'text' => $button_cancel, 'callback_data' => '/cancel'
              ), 
            ),
        ),
      );

And if now there are no other ways, how then can you specify that each button be on a new line when issued? And after 1 click, these buttons disappeared?
