0.4.0

The XApiClientBuilder class now makes use of the SerializerFactoryInterface introduced in release 0.4.0 of the php-xapi/serializer package. By default, it will fall back to the SerializerFactory implemented provided by the php-xapi/symfony-serializer to maintain backwards-compatibility with the previous release. However, you are now able to inject arbitrary implementations of the SerializerFactoryInterface into the constructor of the XApiClientBuilder to use whatever alternative implementation (packages providing such an implementation should provide the virtual php-xapi/serializer-implementation package).
