Welcome to the Zend Framework 2.0.0 Release!

Master: Build Status


Zend Framework 2.0.0

This is the first stable release of the new version 2 release branch.

04 September 2012


New and/or refactored components include:

  • EventManager - provides subject/observer, pubsub, aspect-oriented programming, signal slots, and event systems for your applications.
  • ServiceManager - provides an Inversion of Control (IoC) container for managing object life-cycles and dependencies via a configurable and programmable interface.
  • DI - provides a Dependency Injection Container, another form of IoC.
  • MVC - a newly written MVC layer for ZF2, using controllers as services, and wiring everything together using events.
  • ModuleManager - a solution for providing plug-and-play functionality for either MVC applications or any application requiring pluggable 3rd party code. Within ZF2, the ModuleManager provides the MVC with services, and assists in wiring events.
  • Loader - provides new options for autoloading, including standard, performant PSR-0 loading and class-map-based autoloading.
  • Code - provides support for code reflection, static code scanning, and annotation parsing.
  • Config - more performant and more flexible configuration parsing and creation.
  • Escaper - a new component for providing context-specific escaping solutions for HTML, HTML attributes, CSS, JavaScript, and combinations of contexts as well.
  • HTTP - rewritten to provide better header, request, and response abstraction.
  • I18n - a brand new internationalization and localization layer built on top of PHP's ext/intl extension.
  • InputFilter - a new component for providing normalization and validation of sets of data.
  • Form - rewritten from the ground up to properly separate validation, domain modeling, and presentation concerns. Allows binding objects to forms, defining forms and input filters via annotations, and more.
  • Log - rewritten to be more flexible and provide better capabilities surrounding message formats and filtering.
  • Mail - rewritten to separate concerns more cleanly between messages and transports.
  • Session - rewritten to make testing easier, as well as to make it more configurable for end users.
  • Uri - rewritten to provide a cleaner, more object oriented interface.

Many components have been ported from Zend Framework 1, and operate in practically identical manners to their 1.X equivalent. Others, such as the service components, have been moved to their own repositories to ensure that as APIs change, they do not need to wait on the framework to release new versions.

Welcome to a new generation of Zend Framework!


Zend Framework 2 requires PHP 5.3.3 or later; we recommend using the latest PHP version whenever possible.
