Version Feed

Development

Feed actions

Creating functions called changes or allchanges on any of your page types or controllers will cause confusion with the extensions defined on the extension.

Default RSS action

Templates can offer a "Subscribe" link with a link to the most relevant RSS feed. This will default to the changes feed for the current page. You can override this behaviour by defining the getDefaultRSSLink function in your page type and returning the URL of your desired RSS feed:

:::php
class MyPage extends Page {
	function getDefaultRSSLink() {
		return $this->Link('myrssfeed');
	}
}

This can be used in templates as $DefaultRSSLink.
