Over the weekend I have finally made the jump to 1.8. There, of course, are few changes in this new version, some of the most significant is the introduction of Zend_Application and Zend_Tool. Several blog posts helped me along the way, but I should be honest with you, it took me a good number of hours to assimilate the new â€œBootstrap.phpâ€ paradigm and move my project to the the new way of doing bootstrapping. If you are starting new project, take a look at this clean writeup . I, however, was not starting a new project and needed something that will accommodate a modular directory structure. A good start was this blog post . I hope this two links will help somebody to make the jump to the new Zend Framework version less painful.
