Does this plugin work with WooCommerce 2.0? What about 2.1?

My client has been using this PayHub plugin and when updated to woocommerce 2.1 it broke this plugin.

I fixed this plugin to work with Woocommerce 2.1 using the below code edit:

I replaced this code:

return array(
					'result' 	=> 'success',
					'redirect'	=> add_query_arg('key', $order->order_key, add_query_arg('order', $order_id, get_permalink(get_option('woocommerce_thanks_page_id'))))
					);

With this code:

$result = array(
				'result' => 'success',
				'redirect' => $this->get_return_url($this->order)
				);
				return $result;
