query_posts change in 2.3?

I have upgraded to 2.3. Until this, I used the following syntax for query_posts, that worked out of the box, ordering posts from one category, within the current month.
Is there any change in WP 2.3 code related to query_posts, or there is another way to achieve above mentioned query string?

URL : http://fge.org.ro

Code used

<?php $current_month = date('m'); ?>
<?php $current_year = date('Y'); ?>

<?php query_posts("cat=1&year=$current_year&monthnum=$current_month&order=DESC"); ?>

    <?php if (have_posts()) : ?>
		<?php while (have_posts()) : the_post(); ?>

etc.

Thanks,
Alex
