CHANGELOG
=========

4.3.0
-----

 * Added `PhpSerializer` which uses PHP's native `serialize()` and
   `unserialize()` to serialize messages to a transport

4.2.0
-----

 * Added `HandleTrait` leveraging a message bus instance to return a single 
   synchronous message handling result
 * Added `HandledStamp` & `SentStamp` stamps
 * All the changes below are BC BREAKS
 * Senders and handlers subscribing to parent interfaces now receive *all* matching messages, wildcard included
 * `MessageBusInterface::dispatch()`, `MiddlewareInterface::handle()` and `SenderInterface::send()` return `Envelope`
 * `MiddlewareInterface::handle()` now require an `Envelope` as first argument and a `StackInterface` as second
 * `EnvelopeAwareInterface` has been removed
 * The signature of `Amqp*` classes changed to take a `Connection` as a first argument and an optional
   `Serializer` as a second argument.

   needs to be an associative array or the method name.
 * `StampInterface` replaces `EnvelopeItemInterface` and doesn't extend `Serializable` anymore
 * The `ConsumeMessagesCommand` class now takes an instance of `Psr\Container\ContainerInterface`
