Extension talk:NiceCategoryList2/2.2

could you add a version to the config?

$wgExtensionCredits['parserhook'][] = array(

 'name' =>        'NiceCategoryList',
 'author' =>      'Kichik, Johan the Ghost',
 'url' =>         'http://www.mediawiki.org/wiki/Extension:NiceCategoryList2',
 'description' => 'generate a category page showing all pages in a category, including subcategories',
 'version' =>     '2.2',

);
