 * New ``take`` option to the :func:`.binariseCategorical` processing function,
   which allows the generated columns to contain values from another column,
   instead of containing binary labels.
+* New ``fillval`` option to the :func:`.binariseCategorical` processing
+  function, which can be used in conjunction with ``take``, to specify the
+  fill value for missing rows.
+* Argument **broadcasting** for processing functions - when a process is
+  applied independently to more than one variable, the input arguments to the
+  process may need to be different for each variable. This can be accomplished
+  by using a _broadcast_ argument - simply prefix the argument name with
+  ``'broadcast_'``, and then specify a list containing the argument.
+* Processing functions can now be passed lists of values.
