**Support for polymorphic serialization**
This release adds the Polymorphic and PolymorphicTypes annotations that
can be used on types. Serializers for polymorphic types are not
selected based on the compile-time types of configuration elements, but
instead are chosen at runtime based on the actual types of their values.
This enables adding instances of subclasses / implementations of a
polymorphic type to collections.
**Add SerializeWith annotation**
This annotation enforces the use of the specified serializer for a
configuration element or type. It can be applied to configuration
elements (i.e. class fields and record components), to types, and to
other annotations.
**Add SerializerContext interface**
Instances of this interface contain information about the context in which
a serializer was selected. They are passed to the constructors of custom
serializers if the serializers are instantiated by this library, or can
alternatively be accessed through the new `addSerializerFactory` method
of `ConfigurationProperties` objects.
