I have a code that was working in silverstripe 3.0 to show rss. But the same doesn't work on silverstripe 3.1

The code was put in mysite/code/page.php, which is as follows

<?php
class Page extends SiteTree {
	private static $db = array(
	);
	private static $has_one = array(
	);
}

class Page_Controller extends ContentController {
	private static $allowed_actions = array (
	);
	public function init() {    
		RSSFeed::linkToFeed($this->Link() . "rss");
		parent::init();
	}
	public function rss() {
		$rss = new RSSFeed($this->LatestUpdates(), $this->Link(), "10 Most Recently Updated Pages", "Shows a list of the 10 most recently updated pages.");
		return $rss->outputToBrowser();
	}
	public function LatestUpdates() {
		return Page::get()->sort("LastEdited", "DESC")->limit(10);
	}
}

I was able to access the rss by using the following url

http://my-web-site-add/home/rss

The error that I get on silverstripe 3.1 when following the same process

Action 'rss' isn't allowed on class HomePage_Controller.

Do I need to change something to make this work in silverstripe 3.1

I Think you just need to add rss to static allowed actions
private static $allowed_actions = array (
'rss'
);

Thank you. This works perfectly.
