Roy said in comments of a blog post that Magento would be using the latest version of the Zend Framework which *should* be 1.0.1 and not 0.9beta as it seems is included in the current download.
Just curious, why the change? Did the ViewRenderer in 1.0.0 mess up Magento? And will Magento ever use the latest version of Zend Framework?
Hmm… you probably saw the Zend.php file. It wasn’t recently updated because it’s somewhat deprecated. But Zend/ folder itself is svn external which means it’s the latest update.
