这对于特定的用户登录非常有效：

 global $user_login;
   get_currentuserinfo();
   if ($user_login !== "admin") { // change admin to the username that gets the updates
    add_action( \'init\', create_function( \'$a\', "remove_action( \'init\', \'wp_version_check\' );" ), 2 );
    add_filter( \'pre_option_update_core\', create_function( \'$a\', "return null;" ) );
   }

global $user_ID;
   get_currentuserinfo();
   if ($user_ID !== 1) { // change 1 to the id number that gets the updates
    add_action( \'init\', create_function( \'$a\', "remove_action( \'init\', \'wp_version_check\' );" ), 2 );
    add_filter( \'pre_option_update_core\', create_function( \'$a\', "return null;" ) );
   }

这似乎对我有用：

add_action(\'admin_head\', function() {
    if(!current_user_can(\'manage_options\')){
        remove_action( \'admin_notices\', \'update_nag\',      3  );
        remove_action( \'admin_notices\', \'maintenance_nag\', 10 );
    }
});
