5.0.0.20 (Apr 7, 2013)

Juno 5.0.0.20 is a major update.

##### Core API changes

- New Jena-based {@link oaj.jena.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 {@link oaj.jena.RdfParser} for parsing RDF/XML, RDF/XML-ABBREV, N3, Turtle, and N-Triple back into POJOs.
- `XmlSerializerContext.XML_autoDetectNamespaces` default 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 {@link oajr.annotation.RestResource @RestResource} annotation.
  Serializers, parsers, filters, properties , guards, and converters definitions are automatically inherited from parent classes and interfaces.
- Enhancements to {@link oajr.annotation.RestMethod @RestMethod} annotation:
  - 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 `DefaultJenaProvider` JAX-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 {@link oajr.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.
