Master: 
Zend Framework 2.2.0dev
This is the second minor (feature) release for the version 2 series.
DD MMM YYYY
-
Addition of many more plugin managers and abstract service factories. In order to simplify usage of the
ServiceManageras an Inversion of Control container, as well as to provide more flexibility in and consistency in how various framework components are consumed, a number of plugin managers and service factories were created and enabled.Among the various plugin managers created are Translator loader manager, a Hydrator plugin manager (allowing named hydrator instances), and an InputFilter manager.
New factories include a Translator service factory, and factories for both the Session configuration and SessionManager.
New abstract factories include one for the DB component (allowing you to manage multiple named adapters), Loggers (for having multiple Logger instances), Cache storage (for managing multiple cache backends), and Forms (which makes use of the existing FormElementsPluginManager, as well as the new Hydrator and InputFilter plugin managers).
-
Data Definition Language (DDL) support in Zend\Db. DDL provides the ability to create, alter, and drop tables in a relational database system. Zend\Db now offers abstraction around DDL, and specifically MySQL and ANSI SQL-92; we will gradually add this capability for the other database vendors we support.
-
Addition of Zend\Stdlib\Hydrator\Aggregate. The AggregateHydrator provides an event-driven way to hydrate/extract hierarchical structures, as well as for mapping entities to hydrators for general purpose use.
-
Simplification of dependencies in Zend\Feed. We either removed or made optional several dependencies in Zend\Feed, making it easier to use standalone and/or with third-party components. We plan a larger story around this for 2.3.0.
-
Authentication: The DB adapter now supports non-RDBMS credential validation.
-
Cache: New storage backend: Redis.
-
Code: The ClassGenerator now has a removeMethod() method.
-
Console: Incremental improvements to layout and colorization of banners and usage messages; fixes for how literal and non-literal matches are returned.
-
DB: New DDL support (noted earlier); many incremental improvements.
-
Di: Improvements around the handling of Aware interfaces to prevent attempts to instantiate interfaces when preferences have not been provided.
-
Filter: New DateTimeFormatter filter.
-
Form: Many incremental improvements to selected elements; new FormAbstractServiceFactory for defining form services; minor improvements to make the form component work with the DI service factory.
-
InputFilter: new CollectionInputFilter for working with form Collections; new InputFilterPluginManager providing integration and services for the ServiceManager.
-
I18n: We removed ext/intl as a hard requirement, and made it only a suggested requirement; the Translator has an optional dependency on the EventManager, providing the ability to tie into "missing message" and "missing translations" events; new country-specific PhoneNumber validator.
-
ModuleManager: Now allows passing actual Module instances (not just names).
-
Navigation: Incremental improvements, particularly to URL generation.
-
MVC: You can now configure the initial set of MVC event listeners in the configuration file; the MVC stack now detects generic HTTP responses when detecting event short circuiting; the default ExceptionStrategy now allows returning JSON; opt-in translatable segment routing; many incremental improvements to the AbstractRestfulController to make it more configurable and extensible; the Forward plugin was refactored to no longer require a ServiceLocatorAware controller, and instead receive the ControllerManager via its factory.
-
Paginator: Support for TableGateway objects.
-
ServiceManager: Incremental improvements; performance optimizations; delegate factories, which provide a way to write factories for objects that replace a service with a decorator; "lazy" factories, allowing the ability to delay factory creation invocation until the moment of first use.
-
Stdlib: Addition of a HydratorAwareInterface; creation of a HydratorPluginManager.
-
SOAP: Major refactor of WSDL generation to make it more maintainable.
-
Validator: New Brazilian IBAN format for IBAN validator; validators now only return unique error messages; improved Maestro detection in CreditCard validator.
-
Version: use the ZF website API for finding the latest version, instead of GitHub.
-
View: Many incremental improvements, primarily to helpers; deprecation of the Placeholder Registry and removal of it from the implemented placeholder system; new explicit factory classes for helpers that have collaborators (making them easier to override/replace).
Please see CHANGELOG.md.
Zend Framework 2 requires PHP 5.3.3 or later; we recommend using the latest PHP version whenever possible.
