+
+    *) Изменение: неверные строки заголовка, переданные клиентом, теперь 
+       игнорируется и записываются в error_log на уровне info.
+
+    *) Изменение: при записи ошибок в лог записывается так же имя хоста, 
+       при обращении к которому, произошла ошибка.
+
+    *) Добавление: модуль ngx_http_auth_basic_module и директивы auth_basic 
+       и auth_basic_user_file.
