wp_count_posts – specific category

I have got a full post count using the wp_count_posts method (see below). But I want to display post count for a specific category. Does wp_count_posts support this yet?

wp_count_posts in Codex

<?php
$count_posts = wp_count_posts();
$published_posts = $count_posts->publish;
echo 'Total published items: '.$published_posts;
?>

edit: version 2.5.1 used.
