Rob Allen has three new posts surrounding one these - tutorials for the Zend Framework. One is just an update to his getting started tutorial for the framework, another is the introduction of a new tutorial (covering Zend_Auth), and the final one answers some questions about his "getting started" tutorial people have been having.
The first two, related to his introductory tutorial, announce the release of the latest version (1.3.0, to correspond with the latest Zend Framework release) and questions people have had about it - two questions: "Why did you change the functionality of the BaseURL?" and "In the previous version the template files were called filename.tpl.php. Now they are called filename.phtml. Why did you do this?"
The third post introduces a handy new tutorial that walks you through the use of the Zend_Auth component for the Zend Framework. It gives the exampl eof setting up user information, the changes that need to be made to the bootstrapping file, and creating login/logout functionality (as well as how to protect pages).
