-RELEASE NOTES
---------------------------------------------------------------------------------
- * Prior to JSON-GLib 0.10, a JsonSerializable implementation could
-   automatically fall back to the default serialization code by simply
-   returning NULL from an overridden JsonSerializable::serialize-property
-   virtual function. Since JSON-GLib 0.10 this is not possible any more. A
-   JsonSerializable is always expected to serialize and deserialize all
-   properties. JSON-GLib provides public API for the default implementation
-   in case the serialization code wants to fall back to that.
