Need help with lastposts, please

Hi everybody,

previous versions I was using the following code to retreive last post on my index page, and now it shows not the latest post, but first.

<?php
require('./private/wp-blog-header.php');
?>
<?php get_header(); ?>
<div id="content">

<?php $lastposts = get_posts('numberposts=1');
	foreach($lastposts as $post) :
 	setup_postdata($post); ?>

	<h1 id="post-<?php the_ID(); ?>"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h1>
	<?php the_excerpt(); ?>
	<p class="postmeta"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">Read the complete article</a> | <a href="<?php bloginfo('url'); ?>/index.php" rel="bookmark" title="Go to blog">Go to Blog</a> <?php edit_post_link('#',' | ',''); ?></p>
<?php endforeach; ?>
