When upgrading from a previous release to Zend Framework 0.8 or higher you should note the following migration notes.
Per previous changes, the most basic usage of the MVC components remains the same:
However, the directory structure underwent an overhaul, several components were removed, and several others either renamed or added. Changes include:
Zend_Controller_Router was removed in favor of
the rewrite router.
Zend_Controller_RewriteRouter was renamed to
Zend_Controller_Router_Rewrite, and promoted to
the standard router shipped with the framework;
Zend_Controller_Front will use it by default if
no other router is supplied.
A new route class for use with the rewrite router was
Zend_Controller_Router_Route_Module; it covers
the default route used by the MVC, and has support for controller
Zend_Controller_Router_StaticRoute was renamed
Zend_Controller_Dispatcher was renamed
Zend_Controller_Action::_forward()'s arguments have changed. The signature is now:
final protected function _forward($action, $controller = null, $module = null, array $params = null);
$action is always required; if no controller is specified, an action in the current controller is assumed. $module is always ignored unless $controller is specified. Finally, any $params provided will be appended to the request object. If you do not require the controller or module, but still need to pass parameters, simply specify NULL for those values.
