Release Notes: Zend_Loader::registerAutoload() now proxies to Zend_Loader_Autoloader, and marks the instance as a fallback autoloader. This will ensure equivalent functionality, and reduces the number of deprecation notices emitted to one. Many bugfixes and improvements were made in Zend_Application. Module generation capabilities were added to Zend_Tool. Strong object typing capabilities were added to Zend_Amf. Many more manual translations were included.
