+ChangeLog
+=========
+5.0.3 (2018-05-03)
+------------------
+
+* Dropped remaining hhvm leftovers.
+* #55: Fixed typo in WildcardEmitterTrait (@SamMousa)
+* #54: export-ignore examples & tests in distribution (@staabm)
+
+5.0.2 (2017-04-29)
+------------------
+
+* #50: Fixed Promise\all to resolve immediately for empty arrays (@MadHed)
+* #48, #49: Performance optimisations for EmitterTrait and WildcardEmitterTrait (@lunixyacht).
+
+5.0.1 (2016-10-29)
+------------------
+
+* #45: Fixed `Emitter` class to use the correct interface. (@felixfbecker).
+
+
+5.0.0 (2016-10-23)
+------------------
+
+* #42: The `coroutine` function now supports `return` in the passed generator
+  function. This allows you to more generally return a value. This is a BC
+  break as this is a feature that was only made possible with PHP 7, and
+  before the coroutine function would only ever return the last thing that
+  was yielded. If you depended on that feature, replace your last `yield` with
+  a `return`.
+
+
+4.0.0 (2016-09-19)
+------------------
+
+* sabre/event now requires PHP 7. If you need PHP 5.5 support, just keep
+  using 3.0.0.
+* PHP 7 type hints are now used everywhere. We're also using strict_types.
+* Support for a new `WildcardEmitter` which allows you to listen for events
+  using the `*` wildcard.
+* Removed deprecated functions `Promise::error` and `Promise::all`. Instead,
+  use `Promise::otherwise` and `Promise\all()`.
+* `EventEmitter`, `EventEmitterTrait` and `EventEmitterInterface` are now just
+  called `Emitter`, `EmitterTrait`, and `EmitterInterface`.
+* When rejecting Promises, it's now _required_ to use an `Exception` or
+  `Throwable`. This makes the typical case simpler and reduces special cases.
+
+3.0.0 (2015-11-05)
+------------------
+
+* Now requires PHP 5.5!
+* `Promise::all()` is moved to `Promise\all()`.
+* Aside from the `Promise\all()` function, there's now also `Promise\race()`.
+* `Promise\reject()` and `Promise\resolve()` have also been added.
+* Now 100% compatible with the Ecmascript 6 Promise.
+
+
+3.0.0-alpha1 (2015-10-23)
+-------------------------
+
+* This package now requires PHP 5.5.
+* #26: Added an event loop implementation. Also knows as the Reactor Pattern.
+* Renamed `Promise::error` to `Promise::otherwise` to be consistent with
+  ReactPHP and Guzzle. The `error` method is kept for BC but will be removed
+  in a future version.
+* #27: Support for Promise-based coroutines via the `Sabre\Event\coroutine`
+  function.
+* BC Break: Promises now use the EventLoop to run "then"-events in a separate
+  execution context. In practise that means you need to run the event loop to
+  wait for any `then`/`otherwise` callbacks to trigger.
+* Promises now have a `wait()` method. Allowing you to make a promise
+  synchronous and simply wait for a result (or exception) to happen.
+
+
+2.0.2 (2015-05-19)
+------------------
+
+* This release has no functional changes. It's just been brought up to date
+  with the latest coding standards.
+
+
+2.0.1 (2014-10-06)
+------------------
+
+* Fixed: `$priority` was ignored in `EventEmitter::once` method.
+* Fixed: Breaking the event chain was not possible in `EventEmitter::once`.
+
+
+2.0.0 (2014-06-21)
+------------------
+
+* Added: When calling emit, it's now possible to specify a callback that will be
+  triggered after each method handled. This is dubbed the 'continueCallback' and
+  can be used to implement strategy patterns.
+* Added: Promise object!
+* Changed: EventEmitter::listeners now returns just the callbacks for an event,
+  and no longer returns the list by reference. The list is now automatically
+  sorted by priority.
+* Update: Speed improvements.
+* Updated: It's now possible to remove all listeners for every event.
+* Changed: Now uses psr-4 autoloading.
+
+
+1.0.1 (2014-06-12)
+------------------
+
+* hhvm compatible!
+* Fixed: Issue #4. Compatiblitiy for PHP < 5.4.14.
+
+
+1.0.0 (2013-07-19)
+------------------
+
+* Added: removeListener, removeAllListeners
+* Added: once, to only listen to an event emitting once.
+* Added README.md.
+
+
+0.0.1-alpha (2013-06-29)
+------------------------
+
+* First version!
