Version 0.6 Fatal Error

Updated to 0.6 and got this error:

Fatal error: Call to undefined method CatList::get_categories_posts() in /[...]/wp-content/themes/eatingrules/list-category-posts/recipeindex.php on line 54

I’m using a lightly modified template – here’s line 54 and the next few after:

foreach ($this->catlist->get_categories_posts() as $single):
    //Start a List Item for each post:
    $lcp_display_output .= '<li onmouseover="this.style.background=\'#EEE\';" onmouseout="this.style.background=\'white\';">';

       //Post Thumbnail
    $lcp_display_output .= $this->get_thumbnail($single) ."<br>";

Reverted to 0.59.2 and problem disappeared.
