+New class methods
+-----------------
+
+In case you had extended the classes of the library and added methods to the subclasses, you might find that your
+implementation clashes with the new one if you implemented:
+
+
+| Class | Method | Notes |
+| --------- | ------------ | --------------------------------------- |
+| xmlrpcval | count | implements interface: Countable |
+| xmlrpcval | getIterator | implements interface: IteratorAggregate |
+| xmlrpcval | offsetExists | implements interface: ArrayAccess |
+| xmlrpcval | offsetGet | implements interface: ArrayAccess |
+| xmlrpcval | offsetSet | implements interface: ArrayAccess |
+| xmlrpcval | offsetUnset | implements interface: ArrayAccess |
