0.4.0

• The serializer implementation has been separated from its API definition. This package now no longer ships with an implementation.

  The Symfony Serializer component integration has been moved to the separate php-xapi/symfony-serializer package.

  A default implementation of the SerializerRegistryInterface is still part of the php-xapi/serializer package though.

  This package ships with the following interfaces that must be implemented by packages that want to provide the xAPI serialization functionality:

  • ActorSerializerInterface
  • DocumentDataSerializerInterface
  • StatementResultSerializerInterface
  • StatementSerializerInterface
  • StatementFactoryInterface

  Implementors of the API provided by this package are advised to add the php-xapi/serializer-implementation package to the provide section of their composer.json file.

  The Tests subnamespace of this package contains a set of base abstract PHPUnit test classes integrators can use to make sure that their implementation adheres to the API specified by the php-xapi/serializer package.

• Added a SerializerFactoryInterface that abstracts the creation of serializer instances.

• The SerializerRegistry class is now final. If you need custom behavior inside the serializer registry, create your own implementation of the SerializerRegistryInterface.
