Zend Framework 2.0 (2.0.0dev1)

Yesterday, the Zend Framework team tagged the first development milestone of Zend Framework 2.0 (2.0.0dev1). It is immediately downloadable from the Zend Framework servers:

* Zip package:

http://framework.zend.com/releases/ZendFramework-2.0.0dev1/ZendFramework-2.0.0dev1.zip

* tar.gz package:

http://framework.zend.com/releases/ZendFramework-2.0.0dev1/ZendFramework-2.0.0dev1.tar.gz

NOTE! This release is not considered of production quality, and is released solely to provide a development snapshot for purposes of testing and research. Use at your own risk.

This release is the culmination of several months of work, and incorporates the following features:

* Removal of all require_once statements.

* Migration to namespaces.

* Refactoring of the test suite, including:

* Removal of all “AllTests.php” files.

* Removal of unreferenced test classes.

* Limited refactoring to move helper classes into their own files.

* Refactoring of conditional tests.

* Rewrite of Zend\Session from the ground up. This required creation of a new component, Zend\SignalSlot, for handling observers and creating filter chains.

* Addition of a new Zend\Stdlib namespace for interfaces and utility classes; in particular, we added extensions to SplQueue, SplStack, and  SplPriorityQueue to create serializable versions of these classes.

We have done some “real-world” testing of the release by building the Quick Start application, as well as migrating an existing demo application to ZF2. We were able to achieve both goals, demonstrating that while the release is certainly pre-alpha, it is definitely functional.

There is much work yet to be done. Today, we published a rough roadmap of milestones we will be working towards (1). This roadmap only addresses components with cross-cutting concerns, but serves as a guide for development in the coming months. If you are interested in contributing, be sure to sign our Contributors License Agreement (CLA), and read the “README-DEV.txt” file in the release. We also suggest you join the zf-contributors mailing list (2), and join in discussions on the #zftalk.dev IRC channel on Freenode.
