* Support for dematerializing has been dropped.
+* ``ilist_iterator<T>`` no longer has implicit conversions to and from ``T*``,
+ since ``ilist_iterator<T>`` may be pointing at the sentinel (which is usually
+ not of type ``T`` at all). To convert from an iterator ``I`` to a pointer,
+ use ``&*I``; to convert from a pointer ``P`` to an iterator, use
+ ``P->getIterator()``. Alternatively, explicit conversions via
+ ``static_cast<T>(U)`` are still available.
+
+* ``ilist_node<T>::getNextNode()`` and ``ilist_node<T>::getPrevNode()`` now
+ fail at compile time when the node cannot access its parent list.
+ Previously, when the sentinel was was an ``ilist_half_node<T>``, this API
+ could return the sentinal instead of ``nullptr``. Frustrated callers should
+ be updated to use ``iplist<T>::getNextNode(T*)`` instead. Alternatively, if
+ the node ``N`` is guaranteed not to be the last in the list, it is safe to
+ call ``&*++N->getIterator()`` directly.
