 ### Added
 
+- In order to create tasks in Pipecat it is now recommended to use
+  `utils.asyncio.create_task()`. It takes care of uncaught exceptions, task
+  cancellation handling and task management. To cancel or wait for a task there
+  is `utils.asyncio.cancel_task()` and `utils.asyncio.wait_for_task()`. All of
+  Pipecat processors have been updated accordingly. Also, when a pipeline runner
+  finishes, a warning about dangling tasks might appear, which indicates if any
+  of the created tasks was never cancelled or awaited for (using these new
+  functions).
+
 - It is now possible to specify the period of the `PipelineTask` heartbeat
   frames with `heartbeats_period_secs`.
