+Task Attributes
+^^^^^^^^^^^^^^^
+
+The older ``param_dict`` attribute is now replaced with a method ``as_dict()`` to return a task's all attributes as a dictionary (JSON).
+
+First-level attributes of Task are accessible with ``.`` annotation as the following:
+
+.. code-block :: python
+
+    task.status                   # same as task.as_dict()["status"]
+    task.params["geometries"]     # same as task.as_dict()["params"]["geometries"]
+    task.response["annotations"]  # same as task.as_dict()["response"]["annotations"]
+
+
+Accessing ``task.params`` child objects directly at task level is **deprecated**. Instead of ``task.attribute``, you should use ``task.params["attribute"]`` for accessing objects under `params`.
+
+.. code-block :: python
+
+    task.params["geometries"]   # task.geometries is DEPRECATED
+    task.params["attachment"]   # task.attachment is DEPRECATED
