It finally happened on Friday: version 0.6 of the Zend Framework was released.
Most of the changes were to Zend_Controller. It was adapted to meet the community's needs.
New to the framework is the Zend_GData package. It makes it easy to use the Google API from within the framework.
Zend_Http_Client is now stable too. However, the component's syntax has been adjusted slightly.
A total of 120 bug fixes went into version 0.6.
A brief overview of the components and a description of what's new can be found on Andy Gutmans' blog in the article Zend Framework 0.6 Posted!.
