The new PSR-14 standard for dispatching Events (that is: to extend a Framework without having to modify a frameworks' code) adds a EventDispatcher object that can dispatch Event objects to EventListeners. In PSR-14 every dispatched event is an object. It uses PHP class names as identifiers for events. Class hierarchies may be used to group events. A ListenerProvider object collects available listeners from an extension and allows to listen and/or modify data provided by the Event object. The current implementation relies on a custom TYPO3-specific ListenerProvider that is configured using Symfony's Dependency Injection tags. As an example the Mailer-postProcInitialization signal/slot is replaced by an Event. This first patch introduces the feature, and does not deprecate anything yet. The most important part is that new Events can use this API instead of Hooks in TYPO3 v10. Short-Term goal is to deprecate SignalSlot dispatcher in TYPO3 v10, and migrate all signals to the EventDispatcher.
