+Polynomial Classes no longer derived from PolyBase
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+This may cause problems with folks who depended on the polynomial classes
+being derived from PolyBase. They are now all derived from the abstract
+base class ABCPolyBase. Strictly speaking, there should be a deprecation
+involved, but no external code making use of the old baseclass could be

+Polynomial Classes no longer template based
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The polynomial classes have been refactored to use an abstract base class
+rather than a template in order to implement a common interface. This makes
+importing the polynomial package faster as the classes do not need to be
+compiled on import.
