+  - unmade ``CommentedSeq`` a subclass of ``list``. It is now
+    indirectly a subclass of the standard
+    ``collections.abc.MutableSequence`` (without .abc if you are
+    still on Python2.7). If you do ``isinstance(yaml.load('[1, 2]'),
+    list)``) anywhere in your code replace ``list`` with
+    ``MutableSequence``.  Directly, ``CommentedSeq`` is a subclass of
+    the abstract baseclass ``ruamel.yaml.compat.MutableScliceableSequence``,
+    with the result that *(extended) slicing is supported on 
+    ``CommentedSeq``*.
