Welcome to the Zend Framework 2.0.0 Release!

Master: Build Status


Zend Framework 2.0.0beta5

6 July 2012


This is the fifth and last in a series of planned beta releases. The beta release cycle has followed the "gmail" style of betas, whereby new features have been added in each new release, and BC has not been guaranteed.

Following this release, we plan to perform some repository cleanup, a standards audit, and documentation migration. Once these tasks are complete, we will prepare our first Release Candidate (RC).


PLEASE NOTE: this beta includes a number of breaks from the previous beta. Please read the notes below prefixed with "BC BREAK" for specific breakages. The ZendSkeletonApplication typically reflects any BC changes that have been made, and is a good resource.

  • Escaper component (Padraic Brady)
    • Provides context-specific escaping mechanisms for HTML content, HTML attributes, URLs, CSS, and JavaScript.
    • BC BREAK: The escape() view helper was removed, and replaced with escapeHtml(), escapeHtmlAttr(), escapeJs(), escapeCss(), and escapeUrl() implementations.
  • New I18n component (Ben Scholzen, Chris Martin, Dennis Portnov, Matthew Weier O'Phinney)
    • New component leveraging PHP's ext/intl extension to provide internationalization (i18n) and localization (L10n) features and capabilities to applications.
      • DateTime, DateTimezone, IntlDateFormatter
      • Locale
      • NumberFormatter
    • BC BREAK: REMOVES the following components:
      • Zend\Currency
      • Zend\Date
      • Zend\Locale
      • Zend\Measure
      • Zend\Translator
      • All filters, validators, and view helpers that relied on the above.
      • Zend\I18n\Translator, including support for gettext and PHP-array-based translations (more are planned).
      • Zend\I18n\Filter, containing localized filtering capabilites for Alnum (alphanumeric), Alpha (alphabetic), and NumberFormat (numerical strings).
      • Zend\I18n\Validator, containing localized validation capabilities for Alnum (alphanumeric), Alpha (alphabetic), Iban (international bank account number standard), Int (integer), and PostCode (localized postal codes).
      • Zend\I18n\View, containing localized view helpers for CurrencyFormat, DateFormat, NumberFormat, Translate, and TranslatePlural.
  • Db layer additions (Ralph Schindler, Rob Allen, Guillaume Metayer, Sascha Howe, Chris Testroet, Evan Coury, Ben Youngblood)
    • Metadata support
    • Postgresql adapter/driver
    • New HydratingResultSet, allowing the ability to specify a custom hydrator (from Zend\Stdlib\Hydrator) for hydrating row objects.
    • Many bugfixes and stabilizations
  • Form additions (Matthew Weier O'Phinney, Michaël Gallego, Yanick Rochon)
    • Annotations support: Ability to use annotations with a domain object in order to define a form, fieldsets, elements, inputs and input filters, and more.
    • Hydration of fieldsets; fieldsets may compose their own hydrators if desired.
    • Collection support; allows multiple instances of the same fieldset. As an example, you might have an interface that allows adding a set of form elements via an XHR call; on the backend, these would be defined as a collection, allowing arbitrary numbers of these fieldsets to be submitted.
    • New view helpers covering most HTML5-specific element types, most XHTML-specific element types. Additionally, a number of the HTML5-specific element types now have Element implementations to create turn-key solutions that include validation and filtering.
    • BC BREAK: Options support. Many attributes were being used not as HTML attributes but to define behavior. The ElementInterface now has an accessor and mutator for options. Examples of options include labels for non-radio/checkbox/select elements, the CAPTCHA adapter for CAPTCHA elements, CSRF tokens, etc. If you were defining labels in your forms, please move the label and label attributes definitions from the "attributes" to the "options" of the element, fieldset, or form.
    • BC BREAK: new interface, ElementPrepareAwareInterface, defining the method "prepareElement(Form $form)". The FieldsetInterface, and, by extension, FormInterface, extend this new interface. It is used to allow preparing elements prior to creating a representation.
  • MVC additions (Kyle Spraggs, Evan Coury, Matthew Weier O'Phinney)
    • New "Params" controller plugin. Allows retrieving query, post, cookie, header, and route parameters. Usage is $this->params()->fromQuery($name, $default).
    • New listener, Zend\Mvc\ModuleRouteListener. When enabled, if a route match contains a "__NAMESPACE__" key, that namespace value will be prepended to the value of the "controller" key. This should typically be used in the root route for a given module, to ensure controller names do not clash.
    • Bootstrap simplification. A new "init()" method was created that accepts the path to a configuration file, and then creates and bootstraps the application; this eliminates all common boilerplate for the bootstrap scripts.
  • Hydrator changes (Adam Lundrigan)
    • BC BREAK: the ClassMethods hydrator now assumes by default that it should convert between underscore_separated names and camelCase.
  • BC BREAK: Doctrine Annotations Parser (Matthew Weier O'Phinney, Marco Pivetta, Guilherme Blanco)
    • Zend\Code\Annotation now has a dependency on Doctrine\Common for its annotation parser.
    • Annotations now conform to Doctrine's standards by default, but the AnnotationManager in ZF2 allows attaching alternate parsers for specific annotation types.
  • BC BREAK: Removal of Plugin Broker usage (Matthew Weier O'Phinney, Evan Coury)
    • All uses of the Plugin Broker / Plugin Class Locator combination were removed. A new class, Zend\ServiceManager\AbstractPluginManager, was created and used to replace all previous usages of the plugin broker. This provides more flexibility in creation of plugins, as well as reduces the number of APIs developers need to learn.
    • Configuration of plugin managers is now done at the top-level. All plugin manager configuration follows the format utilized by Zend\ServiceManager\ServiceConfiguration, and Zend\ModuleManager\Listener\ServiceListener has been updated to allow informing it of plugin manager instances it should manage, as well as the configuration key to utilize.
  • BC BREAK: Coding Standards (Maks3w, Sascha Prolic, Rob Allen)
    • Renamed most abstract classes to prefix them with the term "Abstract". In particular, ActionController and RestfulController are now AbstractActionController and AbstractRestfulController.
    • Renamed getters in HTTP, EventManager, and Mail components. These components were using accessors such as "events()", "query()", "headers()", etc. All such accessors were renamed to prepend "get", and, in the case of "events()", renamed to indicate the actual object retrieved ("getEventManager()").
  • SECURITY FIX: XmlRpc (Matthew Weier O'Phinney)

Over 400 pull requests for a variety of features and bugfixes were handled since beta4!
