News and Releases

• PHP 7.3.4
• PHP 7.2.17
• PHP 7.1.28
• Packagist.org moves to AWS
• PhpStorm 2019.1 - Debug Twig and Blade templates, search for dead code, improved auto-completion and much more.
• Adopted PSR-14 Event Dispatcher - The new standard governs the work with events in the application. The document defines three interfaces EventDispatcherInterface, StoppableEventInterfaceand ListenerProviderInterface, and also describes the characteristics that must comply with all the elements and recommendations for implementation. You can read more in a series of posts from one of the members of the working group of the Larry Garfield standard.
  It is noteworthy that the new dispatcher in Symfony 4.3 , in fact, is compatible with the standard, but at least because of the use of the typehinta object, which is available only in PHP 7.2+, it is not yet possible to use the standard directly in Symfony.
  Another example implementation of the yiisoft / event-dispatcher standardlikely to be used in Yii 3.
