   through the pipeline without the need to inject processors in the

+  debuggers among other things. The example
+  `examples/foundational/30-observer.py` shows how to add an observer to a

 - Introduced heartbeat frames. The pipeline task can now push periodic
   heartbeats down the pipeline when `enable_heartbeats=True`. Heartbeats are
   system frames that are supposed to make it all the way to the end of the
-  pipeline. When a heartbeat frame is received the traversing time (i.e. the time
-  it took to go through the whole pipeline) will be displayed (with TRACE
