has wpmu_new_user been replaced

Hi,

I’m using a plugin that makes use of that hook to give new WPMU registrations a permission in bbpress. This had been working on a WP 3.0 MU install of about two weeks ago. After updating yesterday it’s not working. Is there any chance that wpmu_new_user has been changed to something else?

Here’s the full code of the plugin which is installed in mu-plugins:

<?php
/*
Plugin Name: WPMU Enable bbPress Capabilities
Version: 0.1
Plugin URI: https://www.michaeleagan.com/plugins/wpmu-enable-bbpress-capabilities/
Author: Michael Eagan
Author URI: https://www.michaeleagan.com/
Description: Enables bbPress member capabilities when a user is created within WPMU. This allows immediate login as a 'member' after a user is created in WPMU.
*/

function enable_bbpress_forum_capabilities( $user_id )  {
	update_usermeta($user_id, 'bb_capabilities', array('member' => true));
	return;
}
add_action('wpmu_new_user', 'enable_bbpress_forum_capabilities');

?>
