On the Zend Framework blog they've posted an announcement about the release of the latest version of their framework, the Zend Framework v3.
After 17 months of effort, hundreds of releases, tens of thousands of commits by hundreds of contributors, and millions of installs, we're pleased to announce the immediate availability of Zend Framework 3.
[...] For Zend Framework 2 MVC users, the differences are subtle. [...] Migration from version 2 to version 3 was at the top of our minds, and we have provided a number of forwards compatibility features over the course of ZF3 development, and written migration guides to help you navigate the changes.
They also mention updates to the skeleton application for this latest release including the work they've done to make the framework and its components more isolated and have fewer dependencies.
