+Release 1.3.0
+-------------
+
+* Performance improvments for hierarchical clustering (at the cost of memory)
+* Cluster instances are now iterable.It will iterate over each element,
+  resulting in a flat list of items.
+* New option to specify a progress method. This method will be called on each
+  iteration for hierarchical clusters. It gives users a way to present to
+  progress on screen.
+* The library now also has a ``__version__`` member.
