sabre/event 4 released

We just released sabre/event 4.0.0.

This release requires PHP 7, and has the following new features:

  • PHP 7 typehints where they make sense, strict_types used everywhere.
  • Support for a new WildcardEmitter this Emitter has the same interface as the regular Emitter, but it allows you to listen for events such as updated:*, which would get triggered for any event that starts with updated:.
  • EventEmitter, EventEmitterTrait and EventEmitterInterface are renamed to Emitter, EmitterTrait and EmitterInterface.
  • Promises now correctly handle PHP 7 Trowable.
  • Promises must now be rejected by an object implementing Trowable. In the past it was possible to reject a Promise with any value (like Javascript), but unlike Javascript, you can't throw a string in PHP. I felt that this made the Promise a bit more predictable.

PHP 5.5

sabre/event 3 will continue to be supported. I don't suspect new bugs will appear there though, as it's a fairly simple package.

To upgrade sabre/event, make sure your composer.json requires "^4.0" for sabre/event.
