I'm celebrating [the death of PHP4] with the second release candidate of Zend Framework 1.6.0, which should drop today. There are a ton of new features available that I'm really excited about. I'm not going to go into implementation details here, but instead catalogue some of the larger and more interesting changes that are part of the release.
He mentions the Dojo integration, updates to the unit testing infrastructure, captcha support in the Zend_Form component, Firebug support and included pagination functionality. You can grab this preview release from the downloads page on the Zend Framework website.
