5.0.0.20 (Apr 7, 2013)

Juno 5.0.0.20 is a major update.

##### Core API changes

- New Jena-based RdfSerializer for serializing POJOs to RDF/XML, RDF/XML-ABBREV, N-Triple, Turtle, and N3.
  Serializes ANY POJOs to RDF, even simple objects and primitives.
- New Jena-based RdfParser for parsing RDF/XML, RDF/XML-ABBREV, N3, Turtle, and N-Triple back into POJOs.
- XmlSerializerContext.XML_autoDetectNamespacesdefault changed to true.
  The old default value would cause XML with unmapped namespaces if you didn't manually specify them via the XmlSerializerContext.XML_namespaces annotation.
  While setting the default to true is somewhat slower (since the serializer must crawl the POJO tree to find namespaces), the benefits of having it work out-of-the-box outweighs the performance concerns.
  For developers concerned about performance, they can always change it back to false and specify the namespaces themselves.

##### REST server API changes

- Allow inheritance of @RestResource annotation.
  Serializers, parsers, filters, properties , guards, and converters definitions are automatically inherited from parent classes and interfaces.
- Enhancements to RestMethod @RestMethodannotation:
  - New RestMethod.filters() annotation for defining POJO filters at the method level.
  - New RestMethod.serializersInherit()and RestMethod.parsersInherit() annotations for controlling how serializers and parsers (and associated filters and properties) are inherited from the class.
    This replaces the previous addSerializers and addParsers annotations.
- New RestServletJenaDefault servlet that includes serialization/parsing support for all Jena-based serializers and parsers.
- New DefaultJenaProviderJAX-RS provider that includes serialization/parsing support for all Jena-based serializers and parsers.
- Eliminated RestServletChild class.
  It's redundant with the introduction of inheritable annotations.
- New methods on RestServlet:
  - RestServlet.createConfigFactory()
  - RestServlet.createSerializers()
  - RestServlet.createParsers()
  These augment the existing getBeanContext() / getSerializers() / getParsers() methods.

##### REST client API changes

- New RestCall.setDateHeader(String,Object) method for setting ISO8601 datetime headers.
