Hi, I've read the changelog for the new Liveuser release 0.16.7 Could somebody please explain me in more detail what the changes are in the singleton() method ? I noticed $lu = Liveuser::singleton($conf) does not return an instance anymore, but it's not clear to me (from the changelog or the API docs) how I would now create a new instance. Jeroen

Okay so a simple $lu = Liveuser::singleton($conf, 'somename'); will do the trick. The API docs however state that the signature be an array. This should be changed to string. Also, I think it would be nice if a simple call to $lu = Liveuser::singleton($conf) would still work. I think you could do this by changing the method slightly:

    function &singleton(&$conf, $signature = null)
    {
        static $instances;
        if (!isset($instances)) {
            $instances = array();
        }

        if (is_null($signature)) {
            if (empty($instances)) {
                $signature = uniqid();
            } else {
            	$signature = key($instances);
        	}

} elseif (!array_key_exists($signature, $instances)) {

            $instances[$signature] =& LiveUser::factory($conf);
        }

        return $instances[$signature];
    }

This would create a default signature and I think BC could be preserved this way. Jeroen
