Welcome to the Zend Framework 2.0 Release!

Master: Build Status Develop: Build Status

RELEASE INFORMATION

Zend Framework 2.0.4dev

This is the fourth maintenance release for the 2.0 series.

XX YYY 2012

UPDATES IN 2.0.4

Security Changes

By default, the JsonStrategy and FeedStrategy were selecting their associated renderers based on two criteria: if a ViewModel of appropriate type was present, OR if the Accept header matched certain criteria. It was pointed out that this latter is undesirable when the strategies are enabled globally, as any matching route could be forced to return JSON or a feed -- and potentially expose information not meant for that particular format, or raise exceptions due to containing content not compatible with the format.

In this release, we removed the Accept header detection. To mitigate this, however, a new controller plugin, AcceptableViewModelSelector, was added. This plugin may be invoked from a controller, and based on criteria passed to it, return an appropriate view model type based on matching the Accept header. As an example:

class SomeController extends AbstractActionController
{
    protected $acceptCriteria = array(
        'Zend\View\Model\JsonModel' => array(
            'application/json',
        ),
        'Zend\View\Model\FeedModel' => array(
            'application/rss+xml',
        ),
    );

    public function apiAction()
    {
        $viewModel = $this->acceptableViewModelSelector($this->acceptCriteria);

        // Potentially vary execution based on model returned
        if ($viewModel instanceof JsonModel) {
            // ...
        }
    }
}

You will still enable the JsonStrategy or FeedStrategy at the global level, but they will only be selected now if an appropriate view model is returned by the controller; the above plugin can help you select the appropriate view model based on Accept header on an as-needed basis.

For more changes, please see CHANGELOG.md.
