For the past thirteen years, I've been either consuming Zend Framework or directly contributing to it. Since 2009, I've operated as project lead, and, since then, shepherded the version 2 and 3 releases, added Apigility to the ZF ecosystem, and helped bring middleware paradigms to the mainstream by assisting with the creation of Stratigility and coordination of the Expressive project. As I write this, the various ZF packages have been downloaded over 300 MILLION times, with 200 million of those being in the past 18 months!
One aspect of Zend Framework 3, we paid particular focus on was leveraging the Composer ecosystem. We now provide a number of Composer plugins for handling things such as initial project installation, registering installed modules with the application, and more. It's the "more" I particularly want to talk about.
