+Changed
+^^^^^^^
+
+
+* Modified the :func:`.binariseCategorical` function so that it parallelises
+  tasks internally, instead of being called in parallel for different
+  variables. This should give superior performance.
+* Revisited the :meth:`.DataTable.merge` to optimise performance in all
+  scenarios.
