All customized login code + functionality are gone after update

We use custom login codes in our functions.php, like this:

function custom_login_headerlink(){
	$url = bloginfo('url');
	echo $url;
}

add_filter('login_headerurl','custom_login_headerlink');

function custom_login_logo() {
	echo '<style type="text/css">

xxxxxsome css stylesxxxxxxxxx

	</style>';
}
add_action('login_head', 'custom_login_logo');

After the latest update, none of that works!
This is terrible, we have an ugly wordpress logo there that points to www.ads-software.com instead of our company logo + link.
