Development
-----------


0.5.324
-------

* Add a ``GraphAPI`` utility lazily instantiated with the application token.
* Add an attribute ``object`` to ``ChangeNotification``event.
* ``OrderReceived`` being notified when receiving a real-time payment update
* Add :module:`~pyramid_facebook.tests.integration.test_payments` used in
:module:~pyramid_facebook.tests.functional.test_payments


Breaking Changes
````````````````

* Rename ``OrderCreated`` for :class:`~pyramid_facebook.events.OrderReceived

* Can be sent multiple times for the same order with same or different status

* Rename ``OrderCreationError`` for :class:`~pyramid_facebook.events.OrderProcessingError`


0.4.317
-------

* Added pfacebook-real-time command to update real time subscriptions.
* Breaking changes: namespace is now added by the framework in opengraph URLs.


0.2.246

use the generic OpenGraph view).

-------

* Move predicates from lib to predicates.

canvas.


0.1.127
