Zend Framework 1.0.0 production release: „
I am very proud to announce availability of the first production release of Zend Framework. Many thanks to the scores of PHP developers who have worked for many months to make this product milestone possible. Zend Framework has followed a mission to provide classes that are extremely simple, yet powerful and extensible. Zend Framework is now the best class library available for PHP 5 web application development.“
