Loading additional classes has become more streamlined in CakePHP. In previous versions there were different functions for loading a needed class based on the type of class you wanted to load. These functions have been deprecated, all class and library loading should be done through App::import() now. App::import() ensures that a class is only loaded once, that the appropriate parent class has been loaded, and resolves paths automatically in most cases.
