* Add support for bytes as well as strings being passed to ``Event.attach_content`` * Allow ``ActivitiesClient.activities`` to be get and set/updated * Added ``Client.rbac_b64_token`` to allow getting and setting of the base64 encoded RBAC token string. It is also possible to set the token using a PyRBAC token instance (in the constructors or in the ``rbac_b64_token`` property setter).
